Job Description

You will join a high-caliber team of ex-Jane Street and Cambridge engineers to build the AI operating system for financial modelling.

• Massive growth potential as an early hire in a company targeting a $100B+ market opportunity to redefine how global businesses make their biggest decisions.

What you will do

• Build and optimize high-performance AI agents using MCP, custom skills, and optimized context windows to automate complex financial modeling tasks.
• Lead technical ownership of evaluation pipelines, data collection, supervised fine-tuning (SFT), and reinforcement learning (RL) to make models smarter and more reliable.
• Ship high-quality code at an intense pace using advanced AI tools like Claude Code and Cursor to maintain a high-frequency product iteration cycle.

The ideal candidate

• Proven evidence of being a top-centile engineer with experience building autonomous agents and sophisticated AI tooling in production environments.
• High-agency technical leader proficient in TypeScript and React, with a strong interest or experience in Rust for performance-critical systems.
• Experience in high-stakes technical environments such as competitive programming, quantitative trading, or building foundational agentic systems.
