We're building an AI workforce for UK trades, using frontier AI on a mature, production agentic stack.
We've already run a successful internship programme with students from Oxford and Cambridge, and we're now looking for an exceptional engineer to work on our agentic systems alongside the founders, with a genuine path to a full-time role.
- Posted 9 June 2026
- Applications close 19 June 2026
What you'll do
- Build and extend the evaluation systems we use to measure and improve our AI agents, including our onboarding agent.
- Have real input into the architecture of our agentic system: how the components connect, and how we keep the whole thing reliable in production.
- Run experiments on how our LLMs and agents behave, and turn what you learn into concrete, measurable improvements.
- Work hands-on across the agent stack, from prompting and tools to retrieval, and the data and APIs the agents depend on.
What we're looking for
- In your second, third, or fourth year of a Computer Science or Computer Engineering degree at a leading UK university (e. g. Oxford, Cambridge, Imperial, or UCL).
- Real, hands-on experience building LLM applications. You've built and shipped something with them, not just experimented.
- A deep, genuine interest in LLMs and agentic systems.
- A solid grasp of the fundamentals: databases, APIs, and a real feel for how the moving parts of a system fit together.
- An excellent communicator who explains decisions clearly, in writing and in person.
- Available full-time for a summer internship of around 10 to 12 weeks between June and September, with some flexibility on exact dates to fit your term.
- You have the right to work in the UK (we can't sponsor a visa for this role).
- This role isn't for you if
- you haven't actually built anything with LLMs yet. A genuine interest is great, but it isn't a substitute for hands-on experience.
- you mainly want to build user interfaces. This role is about agents, evaluation, and the back-end systems that sit behind them.
- you're looking for a large, structured graduate scheme. We're a small team, and you'll have real responsibility from week one.
- you aren't studying Computer Science or Computer Engineering at a UK university, in your second year or beyond.
What we offer
- Work closely with the founders on real, production AI systems.
- Genuine input and ownership. The work you do ships.
- A clear path to full-time for standout interns.
- Hybrid working from our London base.
