• Verify BLE/NFC interactions between mobile apps and physical readers across many device models.
• Maintain a device matrix and ensure coverage across OS versions, screen sizes, and OEM variants.
• Test push notifications, deep links, biometrics, secure storage, and credential lifecycle flows.
• Perform exploratory, regression, and acceptance testing for each release.
• File clear, reproducible bug reports with logs, screenshots, and video where useful.
• Contribute to API testing using tools like Postman; write basic automated checks where it pays off.
• Partner with developers, product managers, and customer support to drive defects to resolution.
• Design, develop, execute, and maintain comprehensive test plans, test cases, and validation procedures for Safetrust's mobile applications and supporting web portals.
• Perform functional, regression, integration, exploratory, acceptance, and end-to-end testing across iOS, Android, and web platforms.
• Validate credential provisioning, BLE/NFC communication, wallet integration, biometrics, authentication, and secure credential lifecycle workflows.
• Verify mobile application compatibility across multiple operating systems, device manufacturers, screen sizes, and hardware configurations.
• Develop and maintain mobile device test matrices to ensure comprehensive release coverage.
• Perform API testing using Postman or similar tools to validate backend services supporting mobile applications.
• Create and maintain automated test scripts using Appium, Espresso, XCUITest, Selenium, or other automation frameworks where appropriate.
• Execute usability, accessibility, performance, and security testing to improve the overall customer experience.
• Identify, document, prioritize, and track software defects with detailed reproduction steps, logs, screenshots, videos, and impact analysis.
• Collaborate with Product Management, Software Engineering, Embedded Engineering, Cloud Engineering, and Customer Support to resolve defects and improve product quality.
• Participate in requirements reviews, design reviews, sprint planning, and release readiness activities.
• Validate application integrations with Safetrust readers, gateways, cloud services, APIs, and third-party platforms.
• Monitor application quality metrics including defect trends, regression coverage, release readiness, and production quality.
• Support production issue investigations and customer-reported defects through root cause analysis and verification of fixes.
• Continuously improve testing methodologies, automation coverage, and quality standards across the mobile engineering organization.

Skills & Experience:

• Bachelor's degree in Computer Science, Engineering, or a related field.
• 1–3 years of QA experience on mobile and/or web applications (Junior: 1–2; Middle: 2–3+).
• Solid grasp of QA fundamentals: test planning, test design techniques, defect lifecycle.
