Blueberry Pediatrics | Full-stack Senior or Staff Engineer | REMOTE (US only)

American healthcare is seldom affordable, accessible, or high-quality. We are fixing this for pediatrics. Blueberry is the most affordable option amongst our competitors. We practice the highest quality pediatric telemedicine, as evidenced by our exclusive hiring of board-certified pediatricians and the usage of at-home medical kits. And, we’re accessible 24 hours a day.

Our success is shown in the lives we save, the costs we save our insurers, and our exploding B2B and D2C business.

As you can imagine, pulling off affordable high-quality healthcare is a challenge. It requires a lot of engineering ingenuity, a C-suite aligned with positive patient outcomes above short-term profits, and a great product team.

We use Django, Hotwire Turbo (an HTMX-like framework), Pytorch, Sklearn, and Flutter. Experience in these technologies helps, but what’s more important is general full-stack knowledge, curiosity, and a strong work ethic.

What do y'all think about the latency/quality tradeoff with LLMs?

Human voices don't take 30 seconds to think, retrieve, research, and summarize a high quality answer. Humans are calibrated in their knowledge, they know what they understand and what they don't. They can converse in real time without bullshitting.

Frontier real time-ish LLM generated voice systems are still plagued by 2024 era LLM nonsense, like the inability to count Rs in strawberry. [1]

I'd personally love a voice interface that, constrained by the technology of today, takes the latency hit to deliver quality.

[1] https://www.instagram.com/reel/DTYBpa7AHSJ/?igsh=MzRlODBiNWF...

Not affiliated with Sesame, but this is what the realtime models are trying to solve. If you look at NVIDIA’s PersonaPlex release [0], it uses a duplex architecture. It’s based on Moshi [1], which aims to address this problem by allowing the model to listen and generate audio at the same time.

SkySafe (https://skysafe.io) | Wireless Engineer (SDR) | San Diego, CA | ONSITE (Hybrid)

At SkySafe we build drone detection and tracking at scale.

I am looking for a Wireless Communications Engineer with SDR expertise to join my team - I'm the hiring manager.

I need someone with a very strong background in signal theory and experience building software wireless modems. You will spend time learning about new systems from our reverse engineers (no RE experience required!), implementing both open and recovered specifications, and refactoring existing modems code to improve it in both theory (ie - what is the algorithmic state of the art for demodulating xyz thing) and practice (ie - how much memory bandwidth and CPU are you using where). As such, I'm looking for someone with true software modem experience; while DSP, FGPA, and generated code experience are useful and relevant, you'll need to be able to read and write C++ directly.

I need someone who can come into the office in San Diego as needed to work with hardware, so this is a hybrid on-site role. This position requires access to technology which is controlled by US Export laws, so you also need to be an eligible US Person.

What we have to offer: $145-200k. Fun, small team dynamic. Work with experts in adjacent fields. Startup environment with good work-life balance and limited red tape. Rapid iteration and feedback in the wild. Good equipment at the office.

Apply: brian@ for a direct line, https://jobs.lever.co/skysafe for the formal route (we have some other roles I'm not the HM for listed there, too, if you're interested in the company!)

Zed Industries | North America, South America, Europe REMOTE | https://zed.dev/ Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career.

We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

Deep Systems | Senior DevOps Engineer | Remote EMEA, APAC, and Americas | Full-time

I am building a DevOps team at a capital markets tech company most people haven't heard of — but some of the world's biggest financial institutions run on our platform. 300B+ messages/day. 99.99% uptime. Mostly on-prem, Linux, purpose-built hardware.

You'd be working on systems support, tooling, and helping build a custom observability platform in Python — because off-the-shelf monitoring doesn't cut it at this scale.

The vibe: small global team (US/APAC/EMEA), fully async, deeply technical. Leadership still codes. No hand-holding, no fluff.

Mainly focused on US and EMEA hires (we currently have people clustered in Belfast and North Macedonia); for APAC, we have solid leads. We don't have salary expectations to publish. We are open to different engagements given regional and your personal factors, including contract, W-2, contract-to-hire, etc.

Senior IC role, report to me directly.

Osaurus | Full-Time | Remote | Protocol Engineer

Osaurus is a native macOS AI platform. The core idea: inference is a commodity — everything else (context, memory, tools) should be owned by you, locally. Think of it as the runtime layer for AI on Mac that works with any provider (OpenAI, Anthropic, xAI, local models via MLX).

3.7K+ GitHub stars and 54K+ downloads with zero marketing spend. Open source, local-first, provider-agnostic.

Softmax | softmax.com | San Francisco (onsite) | Full-time

THE MOST IMPORTANT UNSOLVED PROBLEM IN AI IS THE MOST POWERFUL OF ALL CAPABILITIES: ALIGNMENT.

Hi, I'm Emmett. You may know me as the founder of Twitch (YC S05), and as the (extremely) interim CEO of OpenAI.

I believe the question of how AI systems learn to understand themselves and others is one of the most consequential technical problems of our time. If we get it right, the agents we build today will become our friends and collaborators tomorrow. And the infrastructure required to train agents that are good at working in teams and societies will be extraordinarily valuable.

Softmax is building large-scale multi-agent, multi-policy environments that will benchmark AI agents – both our own and others – on their capacity for theory of mind, adaptive goal setting, and teamwork. We’re looking for the engineers who will make that possible.

The work is unusually hard. The problems are ambiguous and challenging. High autonomy, high expectations. You'll work directly with me and the rest of our small but mighty team.

If this sounds exciting, I’m looking forward to meeting you. E

Lead Full-Stack Engineer Marker Learning | Remote (U.S. only) | Full-time | Engineering | 185-250k

I have dyslexia. I was one of the lucky ones. Diagnosed at eight, I got accommodations and support before things spiraled.

Most kids aren't so lucky. The path from initial concern to diagnosis can take years and cost families upward of $5,000. For many, it never comes at all. In one study, 50% of prisoners were found to be dyslexic, with 80% functionally illiterate. Behind every missed diagnosis is a kid who gets told they're lazy, when the reality is no one ever gave them the right test.

Marker Learning is building an AI-enhanced assessment platform that makes identifying learning differences faster, cheaper, and more equitable, especially for multilingual students who are routinely misidentified or overlooked. Imagine if every kid could be screened for learning differences as easily as they're screened for vision. That's what we're building.

This isn't a chatbot or a homework helper. We're a Series B company backed by Reach Capital, Andreessen Horowitz, and Primary, running a multi-million-dollar longitudinal study spanning K–12 and developing the psychometric engine behind it. We need engineers who are excited by that.

We're hiring a hands-on full-stack engineer (React, Node.js, TypeScript) to help build and scale the platform: adaptive testing infrastructure, AI-powered scoring scoring and data pipelines, and the systems that maintain clinical rigor at scale. High autonomy, lightweight process, fast-paced. 8–10+ years, ideally with 0-to-1 or early-stage experience. You'll work directly with psychometrics, product, and data science, and the engineering decisions you make now will define the platform for years.

Reach out directly with your resume and why you want this position to lucie@markerlearning.com. Make the subject "Lead Engineer Application (I am not a bot)".

Fractional AI | Senior/Staff Software Engineer | SF, NY, NC, Dubai | Onsite

We’re a team of experienced generalist SWEs and AI enthusiasts who are building custom AI agents for enterprise clients. You’ll work on 3-4 different projects a year and play a central role on each one. No AI experience required: we are actively trying to be the best place in the world to learn applied AI.

I’m Frank, an engineer here. This is the first services-style company I’ve worked at, so for those of you in a similar boat, this is what I’ve really liked so far:

* The learning rate is super fast. 3-4 client projects a year, each with different tech stacks, products, industries, and architectures.

* Our projects are typically high priority and sponsored by prominent executives. The path here for projects to have real impact on usage or bottom line is much shorter.

* We’re “selling pickaxes during the gold rush”. When AI finds its next killer app, we’ll hopefully be the first to know about it.

We’re hiring SWEs onsite with offices in San Francisco, New York, Durham NC, and Dubai. Feel free to reach out to me directly (frank@fractional.ai) or take a look at the full job posting:

Tether - https://tether.io/ - we are hiring for multiple roles 100% remote.

Fullstack Developers

You'll work across the JavaScript and TypeScript layer of our local AI stack. Depending on the project, you might build user-facing applications (mobile or desktop) or contribute to the platform layer that bridges our C++ inference engines with the app ecosystem. Either path puts you at the heart of making local AI usable: whether you're crafting polished product experiences or building the SDK and bindings that other developers rely on. This role suits engineers who thrive in a full-stack JS environment and want to be part of a system where AI runs privately, locally, and fast.

Apply at: https://tether.recruitee.com/o/middleware-engineer-fullstack...

You will be working on developing cutting edge mobile applications integrating crypto wallets and defi features.

You will also contribute to backend components when needed to support mobile features and unblock mobile delivery.

Apply at: https://tether.recruitee.com/o/lead-software-engineer-mobile...

Product Engineer:

You'll own the vision and execution of local AI products, from roadmap to release. Half your time goes into code, the other half into alignment: defining what to build, why it matters, and how to ship it well. You'll lead a pod of engineers across the stack, ensuring that the power of on-device AI translates into products people actually want to use.

This role is for builders who care deeply about the end result: making local, private, and powerful AI accessible through thoughtfully designed products.

Neoteny AI | Founding Researcher | REMOTE (US East Coast/Europe) / ONSITE (London, NYC)

Neoteny AI is building the sovereign intelligence layer for code. We are a team of builders from Meta, AWS, and NYU who believe that the future of coding intelligence is not a generalist chatbot in the cloud, but a specialized, repository-aware model that lives inside the enterprise perimeter.

We are looking for a founding researcher to lead our core research agenda. You will work at the intersection of representation learning, program synthesis, and efficient inference.

You will figure out how to teach models the latent physics of a codebase, the implicit architectural rules, dependency patterns, and style constraints that generalist models miss. Your work will range from designing new data engines to experimenting with novel architectures that break the memory wall of current transformers.

We are looking for someone with deep ML expertise (PhD or equivalent) who is code-fluent and comfortable writing kernels, not just training scripts.

Apex Dental Partners | Full-Stack Developer | Dallas, TX (Remote US or Hybrid) | apexdp.com

We're a Dental Support Organization running 59 practices across TX/OK/CO/MO/IA/NE/TN/AZ. The unsexy industry description hides what's actually an interesting technical role: a small dev team with real ownership, pushing hard on automation and AI to make dental operations actually work well.

Stack is primarily Rails 7.1 (Hotwire+Stimulus.js), with some React/Electron, C# .NET (OpenDental), and Go — all on AWS.

You'd be joining a tight team where developers own problems end-to-end: from understanding why a billing workflow breaks down, to designing the fix, to shipping it. The domain is surprisingly broad — patient communication, PMS integration, payroll, clinical workflows — and there's no shortage of genuinely novel problems once you learn the business.

Good fit if you like: stable company, small team, broad latitude, and work that visibly matters to the people using it. Not a fit if you need a large eng org — but there's plenty of greenfield work as we're still actively building new features, not just maintaining legacy code.

Comper | Software Engineer #2 (Frontend focus) | €80-110k + equity | Utrecht, The Netherlands | ONSITE | https://comper.io

We make software landscapes understandable and explorable. Our canvas is zoom-to-code, and shows data on overlays from all of the git repos in your company. LLMs go through the codebase and extract the architecture.

We provide clarity when it's most needed: re-orgs, onboarding, explaining the tech stack at board meetings. Or just being stuck in your IDE and want to ask your team mate a question. We'd like to do to large org codebases what Figma did to design.

Comper needs someone that can build revolutionary UIs and go where no man has gone before. Our UI is the core of our product: a zoomable canvas that has all your code, documentation and diagrams on it. We have a long way ahead and need serious thinking to make sure we explain the software stack as simple as can be.

I'm the founder & CTO. We just raised a pre-seed and are now with 6 people. Find the vacancies on our site and send us an email.

You'd build things like: computer vision pipelines for colony picking, interfaces for lab automation workcells, integrations between lab instruments and Benchling. Python, APIs, databases, some frontend.

No PhD or biotech background needed. You'll pick up the biology. We care about solid engineering skills and curiosity about working at the intersection of software and hardware.

Constellation Finance | Multiple Engineering Roles | New York, NY | Hybrid | Full Time

At Constellation, we are building a future where technology is the lethal advantage in credit investing.

Credit documents govern everything from how much debt a company can incur, or pay in dividends, to what they can do with proceeds from selling assets. Hidden debt capacity, loosely drafted provisions, or ambiguous definitions can materially alter recovery, making precise covenant interpretation essential to investing outcomes.

Constellation makes it easy to read credit documents, calculate covenant capacity, and plan liability-management transactions, reducing the mechanical bottlenecks to analyzing credits and generating alpha.

Our team is comprised of subject matter experts who have spent a decade in credit (Goldman Sachs/Citadel), AI/ML researchers, and full-stack engineers who are dedicated to solving frontier problems in their application to the world's largest asset class.

Strobe | Senior Infrastructure & Data Integration Engineer | Brooklyn, NYC | ONSITE | Full-time

Strobe is building the world's largest power plant — not a single site, but a distributed fleet of buildings, batteries, EVs, and generators buying and selling power in real time across wholesale energy markets.

We need a senior engineer to own our data integration and cloud infrastructure layer — the connective tissue between utilities, grid operators, OEM hardware, weather services, and our optimization engine.

What you'd own:

– Wholesale market integrations (NYISO, CAISO, ERCOT) — real-time pricing, capacity markets, demand response signals

– OEM hardware integrations — API and data bridges to building equipment manufacturers for monitoring, control, and telemetry

– Green Button Connect pipelines — ingesting interval consumption, billing, and meter data from utilities (ConEd, PG&E, SCE, etc.) via OAuth2 + ESPI

– Weather and solar forecast data pipelines

– Utility bill reproduction engine — modeling site economics before and after Strobe to forecast financial impact across dozens of rate structures. This simulation infrastructure is core to how we sell and deliver value.

– Event-driven AWS infrastructure (Lambda, API Gateway, AppSync/GraphQL, EventBridge, IoT Core, TimeStream, Amplify, CloudWatch)

– Terraform IaC — real module design, remote state, multi-workspace patterns

– Observability and alerting on systems where downtime means missed market events and real dollars

Strong fit if you have:

– Deep AWS experience (IAM, Lambda, API Gateway, AppSync, EventBridge, TimeStream or similar TSDB)

– Production Terraform (modules, remote state, multi-workspace patterns)

– Extensive Python (pydantic for models, click for CLIs, boto3 for AWS, async pipelines)

– Experience integrating messy third-party APIs at scale (utilities, government, energy, OEMs)

– Comfort with on-call for systems that control physical hardware and move real money

Stack: Python / TypeScript / Rust / Terraform / AWS / GraphQL (AppSync) / MQTT / Grafana — AI-agent-optimized monorepo with deep investment in agent-enabled engineering efficiency.

Small team, high ownership, no layers. 5 days/week onsite at Newlab, Brooklyn Navy Yard.

Gen-Alpha Transistor | Member of Technical Staff (SW Generalist) | Full-Time | Onsite (San Francisco) | https://generation-alpha-transistor.com/

Generation Alpha Transistor (Gen-Alpha) is a San Francisco based start-up, building AI tools for chip designers. It's a space that’s gaining enormous momentum as demand for AI silicon keeps growing.

We’re looking for talented software engineers and language-agnostic developers to join our rapidly growing team, collaborating in-office with the founding engineers. We are a small, all-technical team with PhD grads from Berkeley, MIT, and Carnegie Mellon with extensive tenure in companies like Apple, Amazon, Synopsys, and Cadence. This role will also have direct exposure with customers who are some of the world’s biggest and highest-impact semiconductor designers and fabs.

If you are interested, please send your resume along with you some upcoming availability to henry@gen-alpha.io. If there is a potential fit, I can help get a call set up with you and one of our founding engineers to talk more about the opportunity!

focal | Head of Technology & Applied AI | Remote/Onsite/Hybrid (US)

focal is an institutionally-backed, next-generation venture firm. Currently investing out of fund II (2025 vintage), we lead at the start, often pre-incorporation, with up to $1M. The next great venture firm won't just use AI. It will be AI-native from the ground up - seeing sooner, deciding faster, and building systems that compound across every founder, deal, and outcome. That's how a 5-person team beats a 50-person firm. We're building that firm. You'll own how it gets built.

This is a long-term, high-impact founding role with meaningful financial upside (carry in funds) and ownership over how the firm is built. You'll join as our 5th team member and partner closely with our GPs in a flat structure.

Your core responsibility: Build and own the AI-native operating system that becomes our structural edge.

Why this might be interesting to you: you get carry in our funds, full ownership over architecture and roadmap, and a problem space that's genuinely unsolved. Venture firms haven't been technically reimagined in decades.

Who you are: A founder-type. A builder: Highly technical, deeply curious, high-output, high-agency. You move from idea → architecture → shipped - fast. You want real ownership over process and outcome, not a seat at someone else's table. You've built things from scratch that worked, and you can point to them.

Comp: carry in our funds (your upside is tied to fund returns), competitive cash, 100% healthcare, 401(k), 6 weeks PTO, 3 months parental leave, budget for compute/tools.

We're not asking for a resume. Send us your LinkedIn (and X if you have it) along with your favorite thing that you've built and tell us why you're proud of it. GitHub, side projects, demos, whatever.

SpruceID (YC W21) | REMOTE (US-Based Preferred) | Full-Time | spruceid.com

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.

The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs and credentials. Our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.

We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.

We are hiring skilled engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and have high regard for public servants. We have a strong engineering and customer-oriented culture, and are not simply a SaaS product or AI wrapper. Our roles are not for the faint of heart: you will be expected to work hard and learn a lot in this role.

Our engineers are ambitious to get outcomes for our customers and their constituents. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, figure out stablecoin payments, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.

We are interested in candidates who want to be proud of the meaningful impact they make for society, even if it takes time to get right. This is not the right job for someone who wants to "join a cool new AI startup" that implodes or exits in under a year.

See our roles here: https://jobs.lever.co/sprucesystems/

Docker Inc, Remote (62 positions available) We are rapidly expanding to help developers securely use agentic AI to increase their productivity. We are hiring engineers, data scientist, program manager, product managers, solutions engineers, solutions architects, account executives

Transfyr | Full Stack Software Engineer | Cambridge, MA | Full-time | ONSITE

Transfyr is building physical AI for science.

Why is it that a professional athlete has dramatically more information about every play they make than a scientist has about the cause of any experimental failure? At Transfyr, we are building the infrastructure to make real-world scientific work legible, transferable, and reproducible.

Modern science is capable of extraordinary outcomes, but much of the most important insights never become explicit: how experiments are actually executed, protocols drift, how experts make gametime decisions on the fly, why experiments fail on Tuesdays. This tacit knowledge is rarely captured, making it difficult to reliably reproduce results, much less hand off protocols to new team members or collaborators. We believe our systematic failure to capture tacit knowledge is holding back the entire industry.

We’re building systems that operate directly in real laboratory environments to elucidate, capture, and interpret this missing information. Our platform records and analyzes multimodal data about how scientific work is performed and turns it into durable, operational knowledge. In doing so, we are also building the world’s largest commercial dataset on real-world scientific execution.

This foundation is critical not only for driving elite human performance today, but for enabling meaningful automation tomorrow. Physical AI systems cannot learn from outcomes alone; they require rich, grounded records of how work is actually done in the real world.

Key domains of expertise we’re looking for (hiring from entry level to senior leadership):

- Computer Vision: take messy real-world images and video and make sense of them

- AI / ML Research & Engineering: build the best digital brains to support the best physical brains on the planet

- Full Stack Engineering: integrate our AI and data into tools that solve real customer problems.

A change from when I posted here previously: we are now focused on on-site in-person roles, at our lab/office in Cambridge, MA. And, we are particularly interested in DevOps/backend experience for the full stack role.

If you're interested, apply here! https://transfyr.ai/join-us

Prior Labs | Berlin / Freiburg / NYC | ONSITE & REMOTE (EU) | Full-time

Tables power every clinical trial, financial model, and scientific experiment, but deep learning has mostly ignored them. No natural sequence, no spatial structure, no shared vocabulary across datasets. LLM architectures don't transfer. We built TabPFN, the first foundation model that actually understands tabular data (published in Nature, 3M+ downloads, new SOTA for tabular ML). The hardest problems are still open.

The model is half the product. The other half - training infrastructure, real-time serving, developer platform, reliability - is what turns a research breakthrough into something enterprises trust in production. We're hiring across both.

ML Engineer, Cloud Platform — Design and scale the core infrastructure for serving and finetuning foundation models in production. Early enough that you're making the architecture decisions, not inheriting them.

ML Engineer, Training Infrastructure — Own GPU infrastructure, distributed training performance, and the developer productivity layer (CI, experiment tracking, model registry) that keeps research moving fast.

Full Stack Engineer, ML Platform — Build the product that puts tabular foundation models in users' hands, from data upload through inference and results. You'll work across frontend, backend, and directly with the research team to turn new model capabilities into production features.

Research Engineer, Foundation Model — Design experiments, run ablations, build training infrastructure, contribute to papers. Research engineers here aren't supporting scientists — they are the science team.

Also hiring: Research Scientist, Applied Scientist, Forward Deployed ML Engineer, Developer Relations Engineer, AE, BDR.

20-person team selected from thousands applicants. Backgrounds from Jane Street, Google, CERN, G-Research. Led by Frank Hutter, advised by Yann LeCun and Bernhard Schölkopf. With backing from Balderton, XTX Ventures and leaders at Hugging Face, DeepMind, and Black Forest Labs. Comp competitive with top AI labs, meaningful equity.

Project Healthy Minds | Principal Engineer | NYC (Onsite) | $225-250K

We're a mental health 501(c)(3) nonprofit building a care navigation platform – think "find the right therapist" but across every type of mental health treatment – with insurance awareness and consumer-aligned privacy baked in. Small team, startup pace, mission that matters.

We're an AI-native team – actively experimenting with the best ways to leverage AI in how we build, not just what we build. LLM-powered data enrichment workflows, agent coding teams, the works. You'd own a significant chunk of the architecture and ship across the full stack: NestJS backend, Next.js frontend, data pipelines for provider and condition data. You'll shape eng culture and hiring as we grow.

What we're looking for: someone who's startup tested and ready to be the first FT eng hire in the office. Comfortable making architecture calls and still writing code daily. Experience with data-heavy consumer products (search, marketplaces, health tech) is a strong plus. https://jobs.lever.co/project-healthy-minds/514c5d68-8e18-45...

HomeVision | SF (2-3 days/week) | Full-Time

*Who we are*

We're reimagining what mortgage underwriting looks in a world where engineers and operators gain leverage through the use of modern agentic AI. We're at the forefront of using AI tools to hack our own workflow, but also to build automation and tools for our clients.

We currently work with 8 of the top 20 mortgage lenders in the country. NewRez lending, a publicly-traded, top-5 lender recently selected us to be a cornerstone of their AI underwriting strategy, calling this out on their last quarterly earnings call.

https://www.newrez.com/press-news/strategic-ai-investment-in...

*Who You Are*

While we have a number of roles, we're primarily looking for a specific attitude: talented, motivated individuals who tolerate ambiguity and can bridge the gap between business uses cases and engineered solutions. We believe that modern AI tools bring a great deal of leverage to engineers and we're motivated

We're looking specifically for engineers who can work directly with me (CTO/Co-Founder) and a small group of of SF-based engineers/PMs. In particular looking for a strong Frontend/Design engineer, along with a backend engineer.

We've hired from HN in the past and are excited to keep going.

Private | Senior Reverse-Engineer | Remote (Global) | Part Time (per project)

I'm and old time programmer, almost retired now, want to stay anonymous here. Will do supervising and project management for this job.

Looking for X86 reverse engineer with good experience of C decompilation, knowning modern tools like Reko, Ghidra, BNinja and such, maybe with AI.

Have a few projects to do, quite esoteric. Can support your own projects for old games or other software. Salary is negotiable per project and agreed KPI, like 50K-100K USDT for around a month-long project.

Weekly progress towards agreed goals is expected, with payments due after results reviews. Mostly async communications. Please mail your free form introduction to mcm10000@gmail.com with words "decompile job" in subject.

Gee, with the odd way you speak, like "quite esoteric" and the way you refuse to identify yourself, there's no way you're CCP/DPRK-affiliated and trying to dupe people into doing your dirty work with no intent to ever pay as agreed. No way, no how.

"that's just, like, uh, your opinion, man"

Chestnut | Product Engineers (Backend / Full-Stack) | SF + Seattle (Hybrid) | https://jobs.ashbyhq.com/Chestnut

Chestnut builds the systems insurance carriers actually run their distribution business on. We replace spreadsheets, legacy vendor systems, and manual processes with real-time data, deterministic workflows, and AI-assisted tooling.

This is end-to-end product engineering.

You won’t just write APIs. You’ll design schemas, build backend logic, ship UI, deploy to production, and handle the sharp edges that show up with real customers. The problems are messy and state-heavy: payouts that must reconcile with finance, onboarding flows with regulatory constraints, dynamic hierarchies, retries, chargebacks, partial failures.

We care a lot about correctness. These systems move real money and cannot drift.

Stack: Go, TypeScript/React, Postgres, Temporal, Kubernetes, AWS

We use AI heavily in our workflow — for drafting, refactoring, test generation, and exploring solutions. We expect engineers to use it aggressively. We also expect you to understand what it’s doing, spot when it’s wrong, and maintain strong fundamentals. Taste matters.

You’ll likely thrive here if you: - Have 3–6 years building real product systems - Are strong in at least one typed language and comfortable picking up others - Enjoy owning features end-to-end - Think in terms of invariants, edge cases, and failure modes - Like shipping quickly but cleanly - Want to build systems that operate in production, not demos

We’re a small, high-agency team. You’ll have meaningful ownership and direct impact on customers.

Hybrid in SF and Seattle.

Flux.ai | Sr. Platform, Sr. Front End, Sr. SWE (Agentic Products), Sr. DevOps, | San Francisco, CA | ONSITE | Full-time

Flux developed the first AI Hardware Engineer integrated into a browser-based EDA, where hardware engineers can collaborate live and design hardware together from around the world. Our goal is to democratize the ability to create bleeding edge hardware, and revolutionize how electronics are designed and built.

Our agent isn’t an AI “assistant” bolted onto a legacy CAD tool. It’s built deeply into the system: you give it a job, it proposes a plan, explains decisions, and executes real workflows inside the editor: selecting parts, generating schematics, placing and routing with awareness of constraints, and running checks along the way. It works transparently, seeks feedback, and gets better over time by learning its user’s standards and preferences.

Tech Stack: [TypeScript, React, Node.js, Rust]

-- SENIOR PLATFORM ENGINEER -- Build and maintain user-facing platform features, write TypeScript/Node backend services and React frontend components, and more. Requirements: experienced in shipping production full-stack web apps, integrating and maintaining 3rd party APIs, debugging, cloud hosting [...]

-- SENIOR PRODUCT ENGINEER, FRONT END -- Define and evolve the frontend architecture of a large-scale, real-time browser-based engineering tool, and more. Requirements: React/TypeScript, shipping and iterating on complex interactive web applications, passion for UX [...]

-- SENIOR SOFTWARE ENGINEER, AGENTIC PRODUCTS -- Develop agentic reasoning capabilities, Integrate AI behaviors, perform Instrument telemetry and logging, and more. Requirements: [e.g., experienced with Generative-AI or agentic systems, integrating LLM-based systems, and you have built asynchronous distributed systems in production [...]

-- SENIOR DEVOPS ENGINEER -- You will improve the reliability, availability, and operational health of production systems, and more. Requirements: [e.g., operating and scaling production systems with uptime and latency goals, using observability stacks, defining SLOs/SLIs [...]

Benefits include comprehensive Medical, Dental, Vision, 401(k), and Stock Options so you have true ownership in what we build.

Bubblehouse | Fully REMOTE | Full-Time | $200–250k | Principal Engineer

Bubblehouse is a fast-growing custom loyalty platform, tripling the revenue each year. Headquartered in NYC, the entire team is fully remote and spread across the globe. We power loyalty programs for brands like American Girl and Old Spice.

We’re expanding our lean team of extremely experienced developers. Companies are switching from other platforms thanks to the customizations and flexibility that we offer, enabled by our pace and technical excellence, which we intend to keep for years to come.

We run on Golang and use custom data storage on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap’ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.

Zero lines of React, almost zero third-party dependencies (carefully vetted), every line of JavaScript manually written with respect and understanding of the web platform. We render HTML server-side like it’s 2005.

Looking for:

1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.

2. Thinking and problem solving outside the box. (We don’t _always_ go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)

3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)

4. Broad experience across multiple programming paradigms, platforms and software stacks.

5. Demonstrated care for the software craftsmanship (which can take many forms).

6. Great spoken English, and ability to communicate 9am to noon in New York time zone.

We give you a literally fast-paced environment (with features delivered in days) where you need to solve very challenging problems with practical advanced technology, take on entrenched market leaders, and help entrepreneurs across small and large businesses delight their fans.

Send a plain text cover letter to andrey+hiring@bubblehouse.com. Help us see how you stand out. Summarize your experience. Link to 1–5 impressive things you’ve built and proud of, link to where we can see some of your code, include your portfolio/CV, describe the platforms and stacks you’re an expert in. How did you start programming? What are you most passionate about in technology? What are the most interesting or weird things you’ve done? What are your strongest held professional opinions? Please make your email easy to read, we’ll appreciate that.

(If you have applied before, no need to re-apply, we’ll reach out.)

Nectar Social (https://www.nectarsocial.com) | Software Engineer, Product Designer, Product Manager | Palo Alto, CA | Onsite | Full-time

Hi HN. I am an Engineering Manager at Nectar Social, and we're hiring across product, design and engineering.

The traditional playbook of buying ads on social media platforms no longer works for most brands. Buyers make purchasing decisions from organic conversations on social media platforms like Instagram, Reddit, X, and LinkedIn. Nectar listens to conversations in real time, surfaces actionable insights, attributes engagement to revenue, and drives conversions.

We came out of stealth last year and we are on a fast growth trajectory working with brands like OLIPOP, Hatch, K18, and Little Spoon. The company is ~30 FTEs and has many interesting challenges:

1. We ingest data from major social media which brings scaling and performance problems

2. We run AI agents on the content which requires us to control cost and optimize quality

3. We need to present lots of information about social conversations in an understandable way which requires good design.

4. We need to build resilient systems that can work within the constraints of our third party dependencies.

Our tech stack is React, Typescript, AWS, Pulumi, Postgres, Clickhouse and Turbopuffer. We use AI tools thoughtfully to optimize our daily work - Cursor, Claude Code, Graphite, v0 / Replit, and Granola.

The roles we are hiring for:

- Staff Backend Engineer - https://jobs.ashbyhq.com/nectar-social/e5797dfd-275e-4a7a-b9...

- Staff Product Engineer - https://jobs.ashbyhq.com/nectar-social/2f942c62-bc21-41a2-ae...

- Founding Mobile Engineer (React Native) - https://jobs.ashbyhq.com/nectar-social/192caa1d-8f36-472f-b9...

- Senior Product Designer - https://jobs.ashbyhq.com/nectar-social/673bbd54-9a3b-4478-84...

- Senior Product Manager - https://jobs.ashbyhq.com/nectar-social/b63c6254-df3d-406e-83...

Please email careers@nectarsocial.com with "HN" in the subject line if you're interested.

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security. We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome. We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team. Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git.

We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

-- Junior Software Engineer - Remote (Global), Full-Time

We're looking for remote junior engineers that have 0-3 years of professional experience in software, and 5+ years of curiosity exploring computers, programming, and technical hobby projects. This is an open-ended entry role with mentorship and diverse opportunities to work on all areas of our product: databases, distributed systems, infrastructure and tooling, data analysis, machine learning, frontend/backend web development, APIs, data mining, data modeling, and more. To stand out, please highlight what makes you unique: passion for computing, curiosity and side projects, work ethic, niche research, etc.

Ideally you've already graduated, but if you still have one or more years left of school, please feel free to apply anyway, and if you're the right fit for the team we'll figure out a way to accommodate your schedule. https://www.ycombinator.com/companies/mixrank/jobs/Fnwsojk-j... --

Software Engineer - Remote (Global), Full-Time

We're hiring generalist software engineers to work on web applications, data mining, machine learning/data science, data transformation/ETL, data modeling, database scaling, infrastructure, devops, and more. We'll cater the role to whatever subset of these areas match your interests.

Beneficial experience includes PostgreSQL, Python, Rust, Linux, TypeScript, Nix, frontend/backend web development, and data mining.

Kinelo | kinelo.com | Full-Stack Engineer (AI + Backend) | San Francisco | Onsite

Kinelo manages the new type of hybrid team that will emerge in the future: humans+AI working shoulder-to-“shoulder”.

Our first product helps human software engineering teams deliver more efficiently and more reliably by assisting in coordination and engineering management. But it’s built on a foundational layer that ingests data, knowledge, and process across communications and systems, exposing that to humans and AI alike.

Eventually, Kinelo will become a proper human+AI orchestration layer, managing entire companies, and our goal is to have Kinelo run Kinelo (we already dogfood it today).

We’re looking for high ownership individuals to join our small team and shape its direction. We also just opened a new SF office and new hires will have the ability to help shape company culture, engineering practices, architecture, and roadmap.

We’re well-funded (just raised another round), founded by a serial founder, anti-bureaucratic, and highly technical.

We’re looking for:

- Those who want to go 0 to 1 with high ownership: moving features and products from idea on a napkin, to prototype, to engineering UI, to shipped and polished product

- ~8 years professional experience, including the pre-LLM days with strong CS fundamentals

- A balance of wisdom from experience and optimism about the future

- Strong TypeScript and Postgres (or other RDBMS) experience at scale and with high reliability (SaaS apps, APIs, etc)

- Experience with a variety of technologies, including containerization, distributed systems, and at least one strongly typed programming language (Go, C++, Java, etc)

- Ideally experience with ML and AI systems (though expertise in ML, data science, etc is not needed for this role)

We can’t sponsor visas but relocation assistance to SF is possible.
