  • Build reusable test utilities, mocks, and simulators.
  • Contribute to and help evolve the overall test strategy for one or more products or services

  • Investigate defects and production issues; ensure fixes are validated through automation.


Requirements:

  • 4+ years of experience in Test Automation.
  • Strong hands-on experience in building and maintaining test automation frameworks and API testing tools, not just executing them.
