The role

This role combines research, pushing the frontier of what’s known, and engineering, taking that work and building end-to-end from idea to product.

The research component is broad, and includes focuses on agentic systems (compaction systems, coding agents, managing sub-agents, etc), retrieval and knowledge-base systems, pre-processing and managing large swaths of data, evaluation and experimental setup, etc.

This work is end-to-end and goes well beyond just the research component, often including: forming and testing hypotheses, building the system, and carrying it through to a product people use.

You’ll love this role if you enjoy…

  • Identifying and solving genuinely difficult technical and research-level problems.
  • Working very independently. We expect each person in the team to be able to identify critical problems, and manage a complete end-to-end solution with minimal external help.
  • Both the challenges of research and the hard work (and judgement) needed to create something wonderful in the real world.

Requirements and experience

  • 5+ years of experience working on similar research or engineering problems or at least 2+ years of work and clear evidence of excellence.
  • A strong record of solving hard problems in academic or industrial environments.
  • The ability to develop your own research problem and problem, and leverage that to build robust and scalable products.
  • The ability to learn very quickly, comfort reading frontier papers and digesting them in minutes, the ability to explain ideas clearly and quickly.

What we offer

  • Competitive salary and truly generous stock options.
  • Comprehensive Bupa Private Healthcare and wellbeing allowances.
  • A tax-efficient pension scheme with salary sacrifice.
  • Generous workplace nursery benefit.
  • 34 days of paid holiday, including public holidays.
  • Work-visa sponsorship so you can come build with us in person in London.
  • All the equipment you need to perform at your very best.
