About the Role

As a Software Engineer, you will be responsible for building and improving an innovative AI product focused on financial modeling. You will work on features end-to-end, utilizing cutting-edge AI tools and technologies while taking on increasing technical ownership within a small, elite engineering team.

What You'll Do

• Owning features end-to-end – from Rust services and backend infrastructure through to the frontend.
• Using the latest AI tools and models to ship high-quality software at exceptional speed.
• Building and improving AI agents, including their harness, tools and context optimisation.
• Writing highly performant software – removing allocations, optimising queries and caching aggressively.
• Owning and improving backend infrastructure and CI pipelines.
• Debugging low-level issues and continuously optimising system performance.
• Working closely with design to ensure every feature feels polished, beautiful and consistent.
• Taking increasing technical ownership as the company and product scale.

Who You Are

• Evidence of being a top-centile engineer.
• Exceptional problem-solving ability and strong software engineering fundamentals.
• High agency, determination and a genuine desire to take ownership.
• The ability to move quickly, learn new technologies and wear multiple hats.
• A strong interest in AI and experience using modern AI coding tools effectively.
• The ability to work across the stack rather than being restricted to one area.
• A genuine passion for building great products, not simply writing code.

Bonus Points

• Competitive programming experience e.g. Olympiads or Programming Contests.
• Trading or financial technology background.
• AI Tech experience.
• Experience building AI agents.

Why Join?

Join a small, exceptionally strong engineering team with backgrounds including Cambridge and UCL, Jane Street and Bloomberg. Work on a genuinely ambitious AI product tackling a huge, under-served problem.
