Senior Backend Engineer

About

Payment infrastructure is being rebuilt. The systems that handle orchestration, settlement flows, merchant APIs, and financial tooling need to be production-grade, reliable, and owned end-to-end.

This is a Series B fintech building payment infrastructure at scale. The product is live, the commercial traction is real, and the engineering surface is growing with it. The team is fully remote with a high-ownership culture — engineers make architectural calls, not wait for them. This hire joins a growing backend team with direct ownership over core payment services from day one.

What you'll do

  • Design, build, and maintain backend services across the payments platform — payment flows, APIs, data pipelines, and internal tooling
  • Own services end-to-end: implementation, testing, deployment, monitoring, and incident response
  • Make sound architectural decisions: API design, data modelling, error handling, and operational resilience
  • Build observability and reliability into everything shipped: logging, metrics, tracing, and alerting
  • Contribute infrastructure using AWS and Terraform
  • Collaborate across product, finance, legal, and BD; participate in code reviews

What you'll need

  • 5+ years of backend engineering experience in payments, fintech, or high-throughput systems
  • Strong Rust preferred — open to Go, TypeScript, or Node.js for the right engineer
  • Experience owning production services end-to-end in cloud-native environments (AWS)
  • Solid understanding of distributed systems, API design, and data modelling
  • High ownership mindset — you don't wait to be told what to do
  • Comfortable using AI as part of how you build

Optional Bonus

  • Background in payment orchestration, settlement flows, or reconciliation systems
  • Experience with digital or alternative payment infrastructure

Shortlisted candidates will be contacted within 48 hours.
