We’re supporting a well-funded seed‑stage startup who are one of the fastest growing AI startups in Europe, who are looking to make multiple contract frontend engineer hires, with a strong frontend / UI focus, to help shape, ship and influence the core product, bridging the gap between POC's and production ready AI systems.

What We’re Looking For
  • Strong frontend engineering skills with good UI/UX sensibility
  • Solid experience with Type Script
  • Comfortable working across the stack, but frontend‑leaning
  • AI‑curious mindset - already using tools like Cursor, Claude, Copilot, etc. to accelerate coding and experimentation
  • Enjoys building scrappy prototypes and testing ideas quickly
  • Experience in startup or early‑stage environments preferred
  • Independent, clear communicator, and product‑minded
Tech
  • React / Next.js or similar modern frontend frameworks
