Job description

We are looking for a QA Engineer for one of our customer who has an expertise in:-

Key Responsibility

• Device & Hardware Testing: Conduct rigorous testing across multiple physical devices (iOS, Android tablets/phones, desktops, and Smart Home and Health Devices) to verify functionality, responsiveness, and UI layouts.
• Test Execution & Coverage: Develop, update, and execute comprehensive test plans, functional test cases, and exploratory test scenarios for new features and bug fixes.
• Compatibility Testing: Test applications across varying system versions, screen resolutions and hardware specs to identify device-specific issues.
• Defect Management: Identify, reproduce, and document detailed bug reports using tracking tools (Jira, Azure DevOps, Buganizer), including logs, steps to reproduce, screenshots, and video recordings.
• Regression & Sanity Testing: Perform thorough regression cycles prior to production releases to ensure core functionality remains stable.

• Localization (l10n) Testing: Verify translated UI elements across multiple languages for accuracy, context, and formatting compliance (e.g., date/time formats, currency symbols, address layouts, dynamic pluralization, and text truncation/wrap issues).
• Pseudo-Localization: Conduct pseudo-localization builds during early development cycles to catch hardcoded strings, layout clipping, and character rendering errors early in the SDLC.
• Linguistic & UI Quality Verification: Review UI for visual integrity across different screen sizes when localized strings expand or shrink; coordinate linguistic reviews with native-speaking linguists or translation agencies.
