Founding Product Engineer

EngineeringLondonFull-time

We are hiring a Product Engineer to join the founding team and build products for our AI-native certification process.

You should be language-agnostic, reason from first principles, and use LLMs in your daily engineering workflow.

Total compensation of £200k–£400k, including equity.

Apply for this role

What you'll do

  • Own products across the whole stack. Build and ship across front-end, back-end and AI-agent infrastructure. Use AI coding agents like Codex or Claude Code as a core part of your workflow, and own the outcome of what you ship.
  • Build products end-to-end. Design systems from discovery through to production.
  • Engineer reliable agent systems. Design harnesses, evals and safeguards that keep quality measurable.
  • Work directly with our in-house auditors to iterate on the product and try out ambitious agentic AI ideas.

What we're looking for

  • Demonstrable AI engineering depth. You can show real systems where you made substantive decisions about agent harnesses, evals, hallucination containment, performance, agent sandboxing or MCP/tool design.
  • Strong product engineering and technical judgment. You ship across interface, backend, data and deployment, reason from first principles and choose tools deliberately.
  • Product instinct and clear collaboration. You ask good questions, form a view, test quickly, communicate clearly and care whether the work changes outcomes.
  • Evidence of shipped work. Show us professional work, open-source contributions, personal products, research or hackathon results. Roughly 2+ years of experience is useful, but evidence matters more than tenure.
  • Real fluency building production software with AI coding agents. You might have shipped AI agent products to users, or your edge might be raw shipping velocity with coding agents on a more conventional product. Both interest us equally.
  • Comfort with high ownership, scope and speed on a small team, working in the London office five days a week.
