Software Engineer

Our mission is to reinvent how businesses make their biggest decisions.

Tracelight builds AI agents for financial modelling. We have built the most powerful harness for Excel and are now working with 7 of the top 10 consulting firms, alongside PE megafunds and investment banks.

We are building the platform that consulting and finance firms will rebuild around to operate as AI-native businesses - answering what human-AI collaboration looks like when implementation becomes 100x faster. Our work spans new interfaces for human-AI collaboration, our own spreadsheet engine, and agentic, test-driven development for Excel models.

Long-term we will build the AI operating system for the entire strategic decision lifecycle - work that today happens across Excel, PowerPoint, email, and meetings. We believe this category is one of the most fundamental applications of AI, and a $100bn+ opportunity.

We are a small, very strong team, ex Jane Street, Bloomberg, McKinsey, Cambridge, Oxford, UCL. Tech stack is TypeScript for most things and Rust where it matters. The role is 5 days a week in person in our Hoxton (London) office.
