Responsibilities

Define Quality Standards and Requirements: Collaborate with business stakeholders and partner management teams to establish clear quality standards and certification requirements for third-party integrations.
Build solutions that meet performance, memory, and device-level constraints across various SoCs.
Develop Comprehensive Test Plans: Create detailed test plans, scenarios, and procedures specifically tailored to validate partner applications against defined criteria, including functional, non-functional, security, and regression testing.
Contribute to design discussions and support development of distributed UI architecture components.
Implement features within the UI engine and application stack with a focus on performance, smooth rendering, and system stability.
Develop and enhance UI applications running on an embedded Linux environment.
Execute Certification Tests: Conduct manual and automated testing of partner applications in a dedicated testing environment to identify defects and ensure compliance with all requirements.
Manage Defect Reporting and Tracking: Document and report defects, working closely with partner development teams to ensure clear communication of issues and tracking their resolution through the fix and re-test cycles using tools like Jira.
Collaborate with Partners and Internal Teams: Act as the primary QA point of contact for external partners, providing technical guidance, support, and clear feedback to help them meet certification requirements.
Coordinate with internal development and product teams to align on integration points and release schedules.
Verify Compliance and Certify Applications: Conduct final reviews and testing to ensure all issues are resolved and the application meets the necessary quality and compliance standards, ultimately certifying the product for launch or integration.
Automate Testing Processes: Identify and implement opportunities for test automation to improve the efficiency and repeatability of the certification process, using tools and frameworks such as Selenium or Appium.
Create and Maintain Documentation: Develop and maintain comprehensive documentation, including test cases, test results, defect reports, and certification status reports for internal stakeholders and partners.
Monitor Post-Certification Quality: Participate in monitoring live partner application performance and user feedback post-launch to identify and address any production issues or regression defects.
