Full-Stack Developer

full-time
EngineeringRemote (Europe)

We need a versatile engineer who's comfortable across the entire stack. You'll build features end-to-end — from React components to Go API endpoints to PostgreSQL queries. This role is ideal if you don't want to be boxed into 'frontend' or 'backend' and enjoy shipping complete features. You'll rotate across our products, tackling whatever has the highest impact that week.

Requirements

  • 3+ years full-stack experience with React/Next.js + a backend language
  • TypeScript proficiency on the frontend
  • Go or Node.js experience on the backend (Go preferred)
  • PostgreSQL — comfortable writing raw SQL, not just ORM queries
  • Docker basics: writing Dockerfiles, docker-compose for local dev
  • Understanding of authentication flows (JWT, OAuth)
  • Ability to work independently and make technical decisions
  • Bonus: experience with Tailwind CSS and Next.js App Router

$1,500/year professional development budget
$1,000 equipment allowance
