Bonus points for experience with MRAID, VAST, OM SDK, third-party integration testing, and SDK impact measurement on device resources. The position is full-time hybrid in Barcelona, offering a motivated team, competitive compensation, central office with amenities, flexible work-from-home options, training opportunities, meal vouchers, gym allowance, social events, and a diverse, friendly environment.

  • Build and maintain automated UI tests to ensure ad formats (banners, interstitials, video) render perfectly across all screen sizes and OS versions
  • Verify that the full "request-to-render-to-click" flow works as expected, ensuring 100% accuracy in tracking and attribution signals
  • Manage and expand internal testing apps to simulate different publisher environments and edge cases
  • Oversee the performance of internal testing apps distributed at strategic locations worldwide to ensure consistency across different network conditions

Requirements

  • 4+ years of experience as a QA Automation Engineer
  • Solid background in automated UI testing for native iOS and Android
  • Proficient in using proxy tools (Charles Proxy, Proxyman, or Fiddler) to intercept and validate network traffic and event firing
  • Experience with mobile CI/CD pipelines and distributing builds
  • "Pixel-perfect" mindset to catch rendering glitches or UI inconsistencies that could impact ad performance
  • Ability to identify which high-impact UI flows require automation versus manual exploratory testing
