AI Engineer | YC-Backed InsurTech | Founding Team | £90K-£165K + Equity


I'm working with an exceptional YC-backed InsurTech in London that's gone from £0 to multi-million ARR in just 12 months and is looking for AI Engineers to join their founding engineering team.


Despite being early-stage, they're already punching well above their weight – with major UK insurers onboarded and serious production systems live at scale. This is a rare opportunity to get in at the ground floor of something special.


What you'll be doing:

  • Building AI agents and LLM-powered workflows that process real insurance claims
  • Working directly with founders and insurance specialists to solve complex automation challenges
  • Taking real ownership over AI architecture and technical decisions
  • Shaping the AI/ML engineering culture from day one
  • Building systems that directly impact major enterprise customers


The tech:

  • Python
  • LLMs / LangChain
  • Next.js / Node.js
  • GCP
  • Production AI systems at scale


What's in it for you:


  • £90,000 - £165,000 base salary + meaningful equity
  • Direct impact on product and company direction
  • Work with experienced founders backed by Y Combinator
  • Visa sponsorship available
  • Based in London (30 remote days per year)


What they're looking for:


  • Builders who ship AI agents and workflows (not researchers)
  • Full-stack capability – comfortable across Python backend and frontend work
  • Either: experience at Series B/C/D AI companies (PolyAI, Wayve, Synthesia) wanting more ownership, OR early career at big tech with strong fundamentals
  • Someone who thrives in high-intensity, fast-paced environments
  • A builder who wants ownership, not just tickets to complete


If you're an AI engineer looking to step into a founding team role at a startup with genuine traction and momentum, let's talk.
