Tech Stack:

Our client is 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 integrations into the Windows ecosystem.

This role sits within a deeply technical team building endpoint security and system-level compatibility software for unmanaged or BYOD endpoints. You’ll work side-by-side with developers who write kernel-mode and user-mode code.
