Software Engineering Intern

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.

Apply for this role

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.

How to apply

Send us your CV and a short note on why you'd be a good fit, including a link to something you've built with LLMs (a repo, demo, or write-up) and your GitHub or LinkedIn. We read every application ourselves and aim to reply within a week, even when the answer is no.
