Full Description
Greetings from Ubique Systems!!!
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.
Internationalization (i18n) Testing: Validate that application architecture supports multi-locale enablement without code modification (e.g., Unicode/UTF-8 support, string externalization, hardcoded string detection, bi- directional text like RTL, variable expansion, and locale-aware sorting/filtering).
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.
TMS & Localization Tooling: Manage translation asset workflows using Translation Management Systems (TMS) such as Smartling, Phrase, Transifex, or Lokalise, integrating them with code repositories and build pipeline
