IT & Software

Founding Engineer (TypeScript/AI)

Oliver Bernard

London · England · United Kingdom

We’re hiring for a seed-stage SaaS startup backed by Balderton (near £5m raised) that’s using AI to fundamentally redefine its product.

The company is pre-PMF and mid-pivot , at a genuine inflection point, and looking for a hands-on engineer (~80% coding) to help shape the product, architecture, and technical foundations from the ground up.

Up to £100k + meaningful equity

🧑 What you’ll be doing

  • Full-stack engineering (backend-leaning): Next.js (FE + BE), Node.js, TypeScript , with some legacy Python
  • Working closely with the CEO & product to shape roadmap and direction
  • Building alongside a small, senior team (3 engineers) with true peer ownership
  • Iterating fast
  • Shipping real-world AI / agentic systems, not proof of concepts
  • Hybrid: 2+ days per week in Moorgate
  • Small, flat team — low ego, high agency
  • Fast decisions, high trust, minimal processes

If you love building SaaS products with AI and want founding-level ownership, we should talk
