Job description

We're looking to hire a Senior Backend Engineer to own critical infrastructure: payment orchestration, merchant APIs, settlement flows, and the services that keep it all running.

What you'll do

  • Design, build, and operate production payment services end-to-end
  • Own your infrastructure (AWS, Terraform)-no separate ops team
  • Ship APIs, data pipelines, and internal tooling with real production stakes
  • Work primarily in Rust and TypeScript

Requirements

  • Senior backend experience shipping and operating production systems
  • Strong API and system design instincts
  • Cloud-native infrastructure ownership (AWS preferred)
  • Clear written communication for a remote, async team
  • Effective use of AI-assisted development with strong human review

Nice to have: Rust, payments/fintech background, crypto/Web3 familiarity Build the infrastructure for onchain payments at scale.
