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
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.

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...

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.

exe.dev | Full time | SF Bay Area | multiple roles
Support Engineer - If you want to use Claude or Codex (or Shelley!) to trawl through our code base, augmented with (carefully scoped) API keys to make our customers lives better, we are hiring.
Designer - If you want to use Claude or Codex (or Shelley!) to make our product functional and beautiful, we are hiring. You do not ship mocks or assets to other teams. There is no other team. You ship by pushing to production. Don't worry, we've got your back.
Software Engineer - If you see a pattern here, we are hiring. Expect to design, build, and run entire subsystems. What matters is attention to product detail and overall architecture, we have agents for writing code.
With significant industry experience, pay will be over $200,000 with meaningful equity.
We are a small team and going to stay one. The focus is building a high-trust environment. Success for us is if you say "I'm going to fix the load balancer" we all sigh with relief, because you are on it and we can rely on you to take on and solve large projects.
Empire Flippers | Remote (no office), all timezones | Full-time | https://empireflippers.com
Empire Flippers is a true global-remote company with travel in our DNA and employees scattered across 5 continents and all sorts of countries. Since I joined 6 years ago, I've personally been to India, the US, Brazil, Ecuador, Colombia, Mexico, the Philippines, China, Japan, Thailand, the UAE, all while working remotely and coding our Ruby on Rails + React app. More about us here: https://empireflippers.com/about-us
Though not as well known in the Hacker News / venture-backed startups sphere, Empire Flippers is widely considered the #1 marketplace for buying and selling online businesses in the 5 to 8 figure USD range.
Think of businesses like --- that recipe site you landed on as the first result when you googled "best chicken tikka masala recipe". Or the Amazon FBA seller whose product you purchased when shopping for "Widget XYZ" (with Amazon FBA, these ecommerce businesses never touch inventory and so it's a fully online business).
Turns out these type of businesses may be earning 10s of thousands of dollars per month in profit (or more!) and when the (often first time) founder is ready to sell, Empire Flippers is the #1 place to do it safely, securely and at a fair market price.
Before I joined Empire Flippers I only had a peripheral understanding of this space, but now that I've been steeped in this industry I can say that this "mini M&A" world is just as exciting as the high-flying unicorns (and decacorns) that we read about daily on Hacker News.
The company is hiring for a few different positions (both technical & non-technical), all of which can be found here: https://empireflippers.com/careers
But in particular, I'm hiring a Ruby on Rails developer to help me continue to build out new features in our Platform, both for customers and to help run our (very extensive) internal operations of vetting incoming businesses, facilitating their sale, and migrating them to the new owner after they've been purchased.
That job ad can be found here: https://empireflippers.com/career/ruby-on-rails-developer/
As mentioned, we are a global-remote company that hires people of all nationalities located in any country in the world.
Hope to see your application soon, and with any questions feel free to email me (Ben) at beng at empireflippers.com

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 [email protected] 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.

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... --

I’m Kiran, Chief of Staff (CoS) at MixRank, a fully remote data startup building go-to-market intelligence. We’re US-incorporated but hire globally, and we’re bringing on new teammates to join a fast-moving team with real ownership and impact.
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.
