Mobile Staff QA Engineer

Accountabilities:

• • Own and continuously evolve the mobile quality strategy, defining the appropriate balance of automated, exploratory, integration, and end-to-end testing across iOS and Android.
  • Design, maintain, and improve scalable mobile automation frameworks using tools such as Appium, Espresso, XCUITest, or Maestro, integrating automated testing into CI/CD workflows.
  • Define testing strategies for mobile-specific scenarios, including application lifecycle, deep and universal links, push notifications, permissions, biometric authentication, gestures, accessibility, localization, and variable network conditions.
  • Establish device and operating system coverage strategies using real-device testing platforms such as BrowserStack, Sauce Labs, AWS Device Farm, Firebase Test Lab, or similar solutions.
  • Lead mobile release quality practices and use crash, performance, and observability data to identify and reduce production risks.
  • Develop and operationalize AI-assisted and agentic testing workflows for test generation, regression identification, execution, and defect detection while maintaining appropriate human validation.
  • Establish measurable standards for AI-enabled testing, including quality, coverage, regression stability, accuracy, defect detection, and clear validation boundaries.
  • Partner with Engineering, Product, Platform, and technical stakeholders to refine requirements, investigate complex device-specific issues, assess quality risks, and define effective validation approaches.
  • Improve QA methodologies, automation frameworks, documentation, metrics, and reusable testing practices.
  • Mentor and coach QA engineers in mobile automation, test design, quality engineering, AI-assisted workflows, and disciplined validation practices.

  Requirements

  • 8+ years of experience in quality assurance engineering, with significant experience testing native iOS and/or Android applications through both manual and automated approaches.
