We're partnering with an exciting, early-stage AI startup building a real-time, autonomous coordination platform that's already deployed in a live airport environment.

  • Reliable AI systems with robust evaluations, permission controls and failure handling.


đź§  What We're Looking For

  • 3+ years of full-stack software engineering experience.
  • Strong TypeScript and Python skills.
  • Experience shipping LLM-powered products into production.
  • Hands-on experience with AI agents, tool calling and workflow automation.
  • Must be a UK citizen and able to work onsite in London.


🔥 Why Join?

  • Founding-level ownership â€” shape the product and technical direction.
  • Build real AI agents solving complex, real-world problems.
  • Work alongside an exceptional founding team.
  • High-impact engineering, significant autonomy and competitive compensation.
