About the job

Are you an experienced AI Engineer who enjoys building AI-powered products that actually make a difference?

This is an opportunity for you to join a small, focused team where your work directly shapes both technical architecture and product direction.

What you’ll be doing:

  • Lead the design and development of production-ready LLM applications and AI agents.
  • Build safe, scalable systems with guardrails for data security, compliance, and reliability.
  • Optimise retrieval-augmented generation (RAG) pipelines for speed, accuracy, and cost.
  • Drive evaluation frameworks to ensure AI outputs are robust, safe, and measurable.

What we’re looking for:

  • 4+ years backend/API experience with TypeScript, Python, or Kotlin.
  • Proven experience shipping LLM applications or AI agents.
  • Strong knowledge of prompt engineering, RAG, embeddings, and vector databases.
  • Passion for solving complex problems and building safe, reliable AI systems.

What's on offer for you?:

  • Salary of £80,000 - £120,000 (Dependent on Experience)
  • Equity stake
  • Flexible working (hybrid 2–3 days/week) – remote options considered.

If you’re excited about building with AI at the ground floor and want real ownership, this is the role for you.
