I'm working with a well-funded capital markets technology business that's building an AI-first platform to solve complex problems across financial services. They're looking to hire a Principal AI Engineer to help shape the next generation of their AI capability.

This is a hands-on technical leadership role for someone who has built and deployed production AI systems at scale. You'll have significant influence over architecture, technical direction and the delivery of AI-powered products, while remaining deeply involved in engineering.

The role

  • Design, build and deploy production-grade AI applications.
  • Architect scalable RAG pipelines, agentic workflows and LLM-powered services.
  • Build reliable AI APIs and backend services using Python.
  • Drive model evaluation, prompt optimisation and AI system performance.
  • Partner with engineering leadership on architecture and technical strategy.
  • Mentor engineers and help establish best practices across the AI function.

What they're looking for

  • Experience building and deploying production LLM applications.
  • Strong background with RAG, AI agents and modern AI frameworks.
  • Experience with vector databases, cloud platforms and scalable distributed systems.
  • A track record of owning complex technical projects from concept through production.
  • Previous experience within financial services or capital markets

Why it's worth exploring

  • Join a business building AI at the core of its product rather than as an add-on.
  • High levels of ownership and influence over technical direction.
  • Solve challenging engineering problems with modern AI technologies.
  • Work alongside experienced engineering leaders in a fast-paced environment.
  • Competitive compensation, bonus and equity.
