🚀 Founding Engineer | Seed-stage AI SaaS (£100k + equity)
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.
đź’° Compensation
Up to ÂŁ100k + 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
🏢 Setup & culture
