About the role

As a Senior Mobile QA Engineer, you will lead the quality strategy for Irth’s mobile applications.

  • Build, maintain, and scale automation frameworks for iOS and Android (Appium, Espresso, XCUITest).
  • Integrate test suites into CI/CD pipelines for fast and reliable feedback.
  • Test mobile applications on real devices using cloud labs (BrowserStack) to measure battery usage, network performance (3G/4G/5G), and memory leaks.
  • Perform backend API testing to validate data integrity between the mobile front-end and servers.
  • Perform exploratory and manual testing to identify edge cases and cover gaps beyond automated coverage.
  • Mentor junior QA engineers and elevate the quality standards across the team.
