What We’re Looking For:

  • 5+ years experience building backend systems (Node.js/Typescript strongly preferred)
  • Solid grasp of PostgreSQL, schema design, and query optimization
  • Deep experience with API development (REST/tRPC)
  • Payment integrations with Stripe/PayPal (bonus for Crypto or MoR experience)
