Do you want to build a predictive AI platform that surfaces opportunities before clients even know they exist?

Have you led end-to-end delivery of LLM / RAG / agentic systems in production?

Ready to become the technical owner of an intelligence engine at an early-stage startup?

A high-growth AI / Fin Tech startup is building a predictive intelligence platform for financial institutions.

Backed by senior ex-consulting and enterprise technology leaders, they’ve already built a functioning MVP and are now hiring their first in-house Lead AI Engineer to take ownership of the core intelligence layer.

The Lead AI Engineer will architect and product ionise advanced LLM / RAG systems, design agentic workflows, own evaluations and guardrails, and integrate AI modules into a scalable enterprise-grade platform. You’ll collaborate with domain experts from corporate and investment banking, helping turn market foresight into actionable intelligence.
