We ship fast, value clean architecture, and work in a modern Typescript/Node.js environment.

Stack Highlights:

  • Integrate and manage third-party payment providers (Stripe, PayPal, Crypto, etc)
  • Drive test coverage and reliability for mission-critical services
  • Contribute to DevOps and CI/CD improvements (Github Actions, Docker, Cloudflare Workers)
  • Document your decisions and leave the codebase better than you found it

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)
  • Familiar with Docker, Github Actions, and modern cloud infra
  • Track record of leading/mentoring engineers in a collaborative remote environment
  • Clear communicator, async-friendly, comfortable in a fast-paced team
