Founding Frontend Engineer

Crewmates

United Kingdom · Nationwide · United Kingdom

You’ll be the technical backbone of a product that lives and dies by how it feels in the hand. The core challenge is making a modular system — habit trackers, shared calendars, to-do lists, and more — feel like one cohesive, real-time experience rather than a collection of widgets. You’ll own the frontend architecture, build real-time collaborative features, and obsess over the micro-interactions that make social features — streaks, nudges, reactions — feel alive rather than mechanical. This is a mobile-first product where every tap carries emotional weight. Stack: Next.js, TypeScript, Supabase, Tailwind CSS.

What we’re looking for

  • Strong experience with React, TypeScript, and modern frontend tooling
  • Comfort with real-time systems — presence, live sync, the kind of UI that feels multiplayer
  • An eye for interaction design. You don’t just implement specs — you notice when a transition feels wrong or a loading state breaks the emotional flow
  • Experience with Supabase, Firebase, or similar backend-as-a-service platforms
  • You’ve built something collaborative before — a shared editor, a multiplayer feature, a social feed — and you understand the edge cases that come with multiple users touching the same data

Compensation

We pay competitively and offer founding-level equity — this is a build-the-company role. Compensation is salaried and open to negotiation based on experience and what you bring to the table.
