Founding Software Engineer – AI (Python / Typescript)

On‑site in London (£10K relocation provided)

Join a deeply technical AI‑native startup founded by PhDs and researchers from Cambridge, Imperial, and other top European and US institutions. This is an opportunity to work directly with a team who’ve published at leading AI conferences, built open‑source tools used across the industry, and scaled high‑performance systems from first principles.

Now, they’re hiring a Founding Software Engineer to help build the next generation of reasoning tools powered by large language models.

The product is already live with paying customers, and the company is well‑funded with serious growth ambitions.

What you’ll work on:

• Architecting and scaling LLM‑powered applications
• Building efficient inference pipelines and backend infrastructure
• Working across the stack to ship production‑grade code fast
• Collaborating directly with the founders and early technical hires

What they’re looking for:

• A degree from a world‑leading university (e.g. Cambridge, Oxford, EPFL, ETH Zurich, ENS, TUM, etc.)
• Experience in AI‑focused products, ideally within a high‑growth or research‑heavy environment
• Strong Python engineering skills; full‑stack capability a bonus (Postgres, Typescript, React)
• A bias toward action, autonomy, and technical depth

This isn’t a typical startup job. It’s a chance to work alongside an elite team of engineers and scientists on hard technical problems — with equity and early ownership in a company building something truly original in the AI space.

If you’re ready to build fast, learn constantly, and work on meaningful AI challenges, we’d love to hear from you.
