  • Ensure app performance, security, and reliability, proactively identifying and resolving bottlenecks in critical payment pathways.

  • Quality-first mindset: Hands-on experience writing robust unit and integration tests for critical app workflows.
  • Collaborative attitude: Strong communication skills and a team-first mindset that thrives in an agile, cross-functional environment.
