AI engineer

Businesses make their biggest decisions on broken tools. We're fixing that, starting with financial modeling – the worst-tooled form of programming. Our AI add-in for Excel is just the beginning; the long-term vision is an AI operating system for the entire strategic decision lifecycle, a $100bn+ opportunity. We're a small, formidable engineering team, with backgrounds from top-tier institutions. This isn't a 'vibe coding' role. You'll join a lean team, focused on making our core AI agent smarter.

• Ship high-quality code at speed, leveraging the latest AI tools and models. AI isn't optional here.
• Enhance our AI agent's intelligence by refining its harness, tools, and context optimization.
• Own the full lifecycle of evaluation pipelines, data collection, Supervised Fine-Tuning (SFT), and Reinforcement Learning (RL).
• Collaborate closely with design to ensure every feature is intuitive and polished.
• Grow into a technical leader, taking ownership of significant parts of our AI roadmap.

• Demonstrable evidence of being a top-centile engineer. No compromises.
• Hands-on experience building your own AI agents, utilizing concepts like MCP, skills, and hooks.
• Exceptional agency and determination to drive complex projects to completion.
• Ability to work 5 days a week, in person, from our Hoxton, London office.
