Mission/Company: We have plants to thank for nearly every aspect of our existence, from the air we breathe to the energy we consume and the food we eat. But today, plant resources, Earth’s life support system, is in need of life support. 40% of plant species are threatened with extinction. We need new ways of collaborating with plants to ensure long-term access to the plant products we need and the ecosystems that provide them. At Foray, we’re building a new operating system for plants. We use the same “hardware," the plant cell, and design ways for these cells to grow in new and productive ways. Spun out of MIT in 2022, Foray combines advanced plant biology with computational tools to reimagine how we propagate, produce, and protect plants. Our biology is already live in the lab. Our software designed to streamline plant growth workflows is entering private beta. We’re looking for a Lead Software Engineer to help bring our software tools to life for a wider group of scientists, growers, and partners.
Role: You’ll be our first dedicated software hire, hands-on from day one. You’ll write code, define architecture, and lay the foundation for a software team that grows with you. You’ll work directly with biologists, engineers, and early users to translate cutting-edge science into usable, scalable tools.
You:
+ 5+ years of experience in a Software Engineering role
+ Strong experience with Python backend development, such as FastAPI and modern Python tooling
+ Expertise in frontend development with React/TypeScript and modern frameworks like Vite
+ Experience with GCP infrastructure, particularly Cloud Run, Spanner DB, and CI/CD pipelines
+ Proven ability to lead technical projects with recent, hands-on software development experience (actively building and shipping features)
+ Comfortable in early-stage environments
+ Nice-to-have: Practical experience with machine learning, data science, or computational biology; experience with predictive modeling, optimization, or inference is a plus.
+ Must be authorized to work in the United States.

Would you like to help tackle one of the most important sectors for the global economy - maritime shipping? We're hiring for multiple roles: software engineers, data analysts, UI/UX designers, implementation managers.
Nearly every person is affected by stuff shipping on the seas - whether its energy, ore, or wind turbines, but the industry itself is antiquated and archaic, and hampered by paperwork and bureaucracy. Our customers are crying out for better solutions. We're looking for people to help us build those solutions.

If you're the sort of person who likes refactoring complex projects to make them more workable, then we also want to hear from you.

For our Data Analyst or Implementation Manager roles:
You'll be helping our customers in maritime shipping get the most from our software. Initially, a lot of that work will be in helping our customers get their data in and out of it. Lot's of MySQL, Metabase, AWS Glue, DBT, or other ETL pipelines.

We’re a small <25 employee firm that builds primarily custom web application software for a wide range of clients—public and private, large and small. We’ve been entirely remote for over 25 years, and have cultivated an asynchronous environment supported by a careful selection of tools and processes to enable people to work flexibly and efficiently. We’ve aimed for consistent steady growth and achieved that by consistently delivering quality software to our clients, and understanding their requirements often better than they do themselves.
Almost everything we code is in Javascript so relevant experience around that, typescript, React, and the Node.js ecosystem is all great.

What if you built a product that helped thousands of engineers build AI features and AI agents? That is what we do at Toolhouse.
We are a high performance team working in the "infra/backend" horizontal space. We are building the infrastructure that powers AI products and agentic workflows.
We're building a team of special people that want to win in Austin.
This is no 9-5 gig. You're in or you're out. This is a startup and we need to ship code to make this thing happen. You will learn to trust your gut feeling and the data attached to any decision, and we do it all together.
We are looking for engineers who are excited to do great work. - Engineers who trust their instincts and who also love to discuss ideas and write them down. Humans invented writing, and built the future. - People who enjoy building developer tools that can really help other developers.
No BS attitude. Just engineers shipping code and having a good time doing it.
The role: You’ll work across our stack (TypeScript, Python, Postgres, Docker), building powerful backend and frontend for a population relying on function calling infrastructure, RAG, evals, and tons of data (prompts).
Perks: Equity vesting from day one, unlimited PTO, lunches, a real family outside of your own.
We’re in-person & in Austin. We do not sponsor visas.
We don't want your resume, show us what you shipped on Github - send it via email to our toolhouse.ai inbox: hello@...
Phosphor enables the development of the built world (e.g. from real estate to energy projects) to be managed agentically by building programming languages and observability primitives (like version control) on top of a hypergraph.
Our primary technical bet is that if you capture annotated "diffs" of user information with the appropriate annotation, you can create path-dependence to train AI models in an AlphaGo like context. By doing so, we achieve agentic experiences for markets that have never even had an opportunity to imagine what life would be like with basic observability.
Our product is similar a combination of Linear and Wolfram, with components and objects that enable advanced financial modeling, legal/regulatory analysis, and geospatial analysis of infrastructure development opportunities.
We're in stealth, but recently venture-backed by one of the best deeptech funds in the market. We're hiring for a few roles at the senior/staff levels: 1. HCI Engineer - You're a prosemirror wizard who probably follows Ink & Switch or the UCSB HCI lab on Twitter; front-end/rich-text/typescript focused; lots of architectural/sync engine work 2. Systems/Compiler Engineer - We design and build dev tools for languages we create that compile into various graph representations. These range from financial modeling calcs (which need to go very fast to support a seamless UX), to computable representations of legal agreements. Extra points if you've worked with hypergraphs. This in Rust but we're exploring a few other languages.

We provide isolated runtimes for executing untrusted code, mostly generated by LLMs. Our sandboxing is powered by a combination of WebAssembly, V8, and microVMs. Our customers do things like extract data from log lines at run time by asking claude-3-7-sonnet to generate a parsing function on-the-fly and then sending it to us for execution.
Things we need help with:
- Our API (https://docs.riza.io/) (Postgres / Go)
- Our account dashboard (Postgres / Go / React / TypeScript)
- Our code execution engine (Go / Rust)
- New products including code generation workflows (Anthropic / OpenAI experience a plus)

Ascertain is a healthcare AI startup backed by Northwell (New York's largest health system) and Deerfield. We're a small team automating the painful admin work that clogs up the U.S. healthcare system — things like prior authorizations, discharge planning, and insurance claims. Our goal is simple: give time back to clinicians so they can focus on patient care, not paperwork.
We've found early product-market fit and are growing the team thoughtfully. We're hiring senior engineers across the stack: backend, frontend, and AI/LLM. We're NYC-based and hybrid (most of us come in ~3 days/week). We're not counting badge swipes — we just want teammates who want to be in the room with us often enough to build trust, have fun, and work on hard problems together!
What we're building:
* A general-purpose automation platform for healthcare ops, powered by LLMs
* A system that reads unstructured documents, fills out payer forms, and explains rejections
* Tools to automate patient discharge planning in hospitals
* A foundation for making AI in healthcare safe, observable, and human-in-the-loop
What we're looking for:
* AI Engineer — experience productionizing LLM apps (agents, RAG, embeddings); solid Python; knows how to build ML systems that ship
* Backend Engineer — strong Python/FastAPI; infra-savvy (K8s, Terraform, Docker); thoughtful about API design and scalability
* Frontend Engineer — React/TypeScript expert who's opinionated about UX and happy to dip into backend when needed
More importantly, we're looking for engineers who like open-ended, ambiguous challenges, and want to work with a tight-knit, high-trust team to solve real-world problems.

Just a team of sharp, kind engineers shipping great code and pushing each other to improve.
The role: You’ll work across our stack (TypeScript, Node.js, Postgres, Kubernetes, Vue 2/3), building powerful APIs and clean UIs that help integrate thousands of school systems. You’ll also work directly with developer clients who use our API — think Stripe for edtech.
Perks: Equity from day one, unlimited PTO, free downtown parking, paid parental leave, relocation support, and weekly team lunches.
We’re in-person in Austin because we believe startups build better products — and have more fun — when they work side by side.

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.

We’re creating robots that autonomously construct buildings. We design all of our hardware and software in-house in central Amsterdam, starting with autonomous bricklaying robots.
Building a robot like this means solving all sorts of interesting challenges: figuring out the robot's position with sub-mm precision; navigating autonomously around the building site; automating measurement and calibration of new robots; lots of distributed systems and so on.
Our robots are now continuously deployed on customer sites and we are earning real money as a masonry contractor. The full team is more than 50 people and we're growing rapidly to meet demand.
Our stack is mostly: Rust, TypeScript, Python, NixOS.
Some open roles:
- Software Engineer, Controls
- Software Engineer, Machine Vision
- Assembly/manufacturing technicians and robot operators

Purplefish is transforming the trillion-dollar talent industry with powerful AI agents that will fully automate most hiring processes end-to-end.
We are funded by 8VC, and Adam and I previously worked closely together to launch 145 companies at the venture studio Fractal Software out of a $650 million fund. Before that I was a staff software engineer at Lyft, and Adam was CRO at Wunderkind ($100m+ ARR). We've built a powerful voice agent, and are expanding into other parts of the sourcing-to-onboarding flow. We have customers, revenue is growing, and so is our team.

I'm trying to build the engineering team that I would want to join, which to me means a high emphasis on agency, purpose, technical excellence, collaboration, learning and velocity. Recently A16Z mentioned us in the state of voice AI report: https://a16z.com/ai-voice-agents-2025-update/
