Senior QA Engineer - Windows Internals

We're looking for a highly technical QA Engineer with deep expertise in Windows internals, networking, and application compatibility testing. You will be responsible for validating low-level functionality such as drivers, hooks, and system APIs across our Windows Secure Enclave platform. This is not a checkbox QA role — you’ll be reverse-engineering app behaviors, designing compatibility matrices, and creating regression suites that validate complex interactions between Windows components, 3rd party software, and other system elements. You will also be expected to collaborate with cross-functional teams to identify and prioritize testing efforts, develop test plans and procedures, and execute manual and automated tests to ensure the quality of our products. In addition, you will be responsible for analyzing and reporting on test results, identifying trends and areas for improvement, and providing recommendations for process enhancements. You should have a strong understanding of Windows internals, including kernel-mode and user-mode components, as well as experience with testing frameworks such as CppUTest or Google Test. Familiarity with Agile development methodologies and version control systems like Git is also highly desirable.
