Toolhouse | Software Engineer (Fullstack) | Onsite (Austin, TX) | Full-time | $180k + Equity

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@...

AMD | Onsite or Remote | SF Bay Area (preferable) or other locations in USA/Europe/Canada | Full-time

We are building a fundamentally new programming language for authoring high performance machine learning kernels on AMD GPUs and the rest of our hardware portfolio. To enable this, we are looking for a wide variety of roles ranging from GPU performance experts, MLIR/LLVM compiler wizards, programming language specialists and machine learning for systems researchers.

We are looking for candidates with deep domain expertise in any of the areas listed above (atleast 5 YoE and contributions to major OSS projects or publications in relevant conferences)

If this sounds interesting, please reach out to me via email (harsh dot menon at amd dot com) with the title "Interested in Wave Language" and your resume along with a brief description of what role you are interested in and why we should consider you for the role.

Sourcetable | Product Education (Contract) | San Francisco, U.S., or Australia.

Sourcetable is building a spreadsheet-based analyst. Talk to the computer, tell it what you want done, and it does the work for you.

This is a new UX, and we're looking for a great product educator to join our team to tell that story and show people how it's done.

You need to be exceptional at making product education videos. These particular videos will be related to using AI for spreadsheet analysis and ops work, flexing up into leveraging any python library you can think of for analysis and other shenanigans. That's the gig.

If you need a lot of guidance it will not be a good fit.

Terradot | Data Science, Computational Research, Statistics | ONSITE in San Francisco, CA or São Paulo, BR | Full-Time

Hi HN, Terradot is a carbon removal company founded out of Stanford University. We are led by the world’s leading experts to advance the science and technology of Enhanced Rock Weathering (ERW), a carbon removal pathway that leverages earth’s natural weathering cycle to draw carbon dioxide out of the atmosphere at the gigaton scale. We just raised ~$60M in funding and have sold 300k tons of offtakes from leading CDR buyers like Frontier and Google.

We’re looking for folks interested in working in a high-performance science and engineering team to develop an engine to jointly quantify and predict CO2 removal in ERW projects. It’s a tough problem spanning geochemical modeling, geostatistical modeling, and integration of complex environmental data. Domain background always appreciated but not required. We're currently working in Python & Julia. Let’s go get this thing.

Entourage | Founding CTO | Remote | Full-time ($230k+ equity)

We're building the protocol layer for collective AI agent intelligence.

Seeking a hands-on, visionary CTO & Co-founder to architect our system (AI, distributed systems, data, infra), build the founding engineering team, and drive technical strategy. This involves deep work in multi-agent systems, collective learning, secure execution, and potentially novel consensus/incentive mechanisms.

Must have: Proven leadership in AI infra (CTO/VP/Founder/Lead Scientist). Expertise in GenAI/RL/DL/MLOps/PyTorch. Experience with agent frameworks (LangGraph, AutoGen, etc.) and distributed/federated AI concepts. MSc required, PhD strongly preferred.
