Every major business decision relies on financial models. Yet, building them is one of the worst‑tooled forms of programming. This company is reinventing how businesses make their biggest decisions, starting with an AI add‑in for complex financial modelling. Their long‑term vision: build the AI operating system for the entire strategic decision lifecycle – a new category with a $100bn+ opportunity. This is a small, elite engineering team, with backgrounds from Jane Street, Bloomberg, Cambridge, and UCL.
You'll join this lean team as an AI Engineer, focused on making their core AI agent smarter. This isn't about 'vibe coding' or dabbling with AI tools. This is about deeply understanding and leveraging the latest models, improving agent harnesses, and owning the full lifecycle from data collection to SFT and RL. You'll ship high‑quality code at speed, with a clear path to technical leadership and significant ownership of the AI roadmap.
The work
- Ship high‑quality code at speed, leveraging the latest AI models and tools. This means deep expertise in prompting, model selection, and practical application (e.g., Claude Code, Cursor).
- Enhance the core AI agent's intelligence by refining its harness, tools, and context optimization.
- Own the full AI lifecycle: from designing evaluation pipelines and collecting data to implementing Supervised Fine‑Tuning (SFT) and Reinforcement Learning (RL).
- Collaborate closely with product design to ensure every AI‑powered feature is intuitive and visually consistent.
- Drive significant parts of the AI roadmap, with a clear path to technical leadership within a rapidly evolving product.
What You Bring
- Unquestionable evidence of being a top‑tier engineer. This is non‑negotiable.
- Hands‑on experience building your own AI agents, including practical application of concepts like MCP, skills, and hooks.
- A high degree of agency and determination; you thrive on solving complex problems autonomously.
- This is a full‑time, 5‑day‑a‑week, in‑person role based in Hoxton, London.
