The Role
We're seeking a Staff Backend Engineer to lead our core product development. Our backend serves a REST API that powers our iOS, Android, and Web frontends. You will integrate with cryptocurrency wallet and banking service providers, among other services for auth, ledger, payment rails, etc.

This is a financial services application with significant complexity handling real money at scale, internationally.

Our backend is a Python (FastAPI) monolith supported by Postgres and Redis on AWS. We are open to Rust and/or Go for any services that need to be broken out for performance.

This is a critically important role on our team. You’ll be working directly with the technical founders to set standards and build a highly performant, reliable, and secure app from the ground up. This role may evolve into a backend or general engineering lead as we scale.

Requirements
  • 5+ years building and shipping web applications in Python, Go, or Rust
  • Experience generally across the backend: working with Postgres, Redis, AWS, etc.
Bonuses
You might be an especially good fit if you have:

  • Experience in financial technology
  • Full-stack engineering skillset and ability to flex across other parts of the stack
