About the Role

Join our Identity Verification team as a Senior Full-Stack Engineer to transform our KYC flow into a versatile service and enhance customer onboarding. You will focus 60% on backend development with Ruby and 10% on Go, and the remaining time on web development.

  • Handle provider failures and retries, improve observability, and operate integrations safely in production.
  • Design a layer to make verification providers interchangeable and decouple the current tightly coupled solution.
