AI Platform Engineer

AI Platform Engineer – £150-200k – 4 days a week in the office

PhD + production engineer? This one’s for you.

I’m partnering with a leading independent global macro research firm, part of a major international financial group. They’re hiring an AI Platform Engineer to turn their AI agents, quant models and data into products that institutional investors use every day.

This isn’t a research role, and it isn’t a pure DevOps role either. It sits between the two: you’ll own tdhe platform that makes AI work in production.

What you’ll own

• Agent runtime infrastructure and model/tool orchestration
• The APIs between data, models and user interfaces
• Auth, permissions, logging, monitoring and audit trails
• Usage, cost and error tracking across LLM workflows
• Internal tools that produce market dailies, consensus summaries and sales-ready content

What they’re looking for

• A PhD (CS, ML, Physics, Maths or similar), ideally followed by time in industry
• Strong Python backend engineering, with FastAPI or similar API design
• Hands-on LLM API and model endpoint integration
• Cloud deployment, observability and production reliability
• Enough front-end ability to put a usable interface on internal tools
• Financial markets experience is a real plus, especially working alongside quants or front-office teams.

Central London, 4 days a week in the office

If you’ve shipped LLM systems to real users and want your work to directly shape investment research, this one is for you.
