60,London Area Are you a recent graduate or early-career engineer with an exceptional technical track record?

Have you studied at a top university, completed internships at leading technology or trading firms, or competed at the highest levels of programming and mathematics?ð Software Engineer – AI x Financial Modelling ðð Salary:
Up to 130k DOE + equityð

Location:

London - onsite 5 days per weekð Will relocate and sponsorð

Experience:

Exceptional engineers 0-2 yearsI’m excited to be working with a very ambitious AI startup reinventing how businesses make some of their biggest decisions. They’re building an AI-native financial modelling platform – essentially Cursor for financial modelling in Excel.

Financial modelling underpins some of the world’s biggest decisions across M&A, private equity, investment, corporate strategy and consulting, yet the tooling remains incredibly manual and outdated.

This team is building something fundamentally different.

They’re now looking for exceptional graduate and early-career Software Engineers to join a small, elite engineering team and work directly on some genuinely difficult technical problems across AI, software performance, financial modelling and product engineering.

This is not a traditional graduate role. You’ll be given significant responsibility from day one, working alongside engineers from some of the strongest technical environments in the industry.ð They’re particularly interested in candidates who have:

Graduated from a top university with an exceptional academic record

Completed internships at leading technology, trading, quantitative or engineering companies

Demonstrated exceptional problem-solving and programming ability

Participated in and ideally placed highly in competitive programming contests, Olympiads or similar competitions

Built impressive technical projects outside of university or internshipsA genuine passion for software engineering and solving difficult problems

The ability to learn incredibly quickly and operate with high autonomyð¡ You’ll work directly on:

Building and shipping production software across the stack

Owning features end-to-end, from backend services through to frontend

Using AI coding tools such as Claude Code and Cursor to dramatically accelerate development

Building and improving AI agents, their tools, harnesses and context optimisation

Writing high-performance software and tackling challenging optimisation problems

Working with Type Script and Rust across a rapidly evolving product

Debugging low-level issues and improving backend infrastructure and CI Collaborating closely with design to build polished, intuitive product experiences

Taking increasing ownership as you develop into a technical leaderð Strong signals could include:

Competitive programming / ICPC experience

Mathematics, Computer Science or another highly technical degree

Olympiad participation or success

Internships at elite technology, trading or quantitative firms

Experience with Rust, Type Script, React or AI agents

Personal projects that demonstrate exceptional technical ability

Experience working with LLMs and modern AI coding toolsð» Tech stack:

Rust Type Script React AI / LLM tooling

Backend infrastructure & Dev Opsð What they’re looking for:

Exceptional technical ability – you’re among the strongest engineers in your peer group

High agency – you don’t wait to be told what to do; you figure things out and take ownership

Intellectual curiosity – you love learning difficult concepts and getting to the bottom of complex problems AI-native mindset – you’re excited about using the latest models and tools to become a dramatically more effective engineer

Speed + quality – you can move quickly without compromising engineering standards

Competitive mindset – you enjoy challenging yourself and solving problems others find difficult

Long-term potential – you want to grow rapidly and eventually own significant parts of a productð Why join?

Join a tiny, exceptionally strong engineering team with backgrounds including Jane Street, Bloomberg, Cambridge and UCLWork alongside engineers who have competed at the highest levels of programming
