The role
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. That means improving its harness, tools, and context optimization. You'll own evaluation pipelines, data collection, SFT, and RL, with a clear path to technical leadership. Expect high ownership, deep technical problems, and a 5-day-a-week commitment in our London office.
The work
- 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.
This is a rare, high-impact AI engineering role at a company solving a fundamental problem. Skip the noise of cold applications and get a direct introduction to a team building truly innovative AI. Dex ensures you're fully briefed and prepared, connecting you to opportunities you won't find elsewhere.
