Responsibilities

• Work with product development teams throughout the product life cycle to ensure software quality requirements and goals are established and met.
• Responsible for automating functional and non-functional tests to reduce test duration.
• Build and maintain automation code and frameworks that test both kernel mode and driver mode capabilities.
• Perform code reviews and white box testing to uncover defects early in the product life cycle.

Requirements

• Strong proficiency in at least two of the following languages: Python, C#, C++.
• Deep experience working directly with Win32 APIs.
• Solid knowledge of Windows OS internals, including COM, IPC mechanisms, memory management, and the Windows security model.
• Experience developing automated test frameworks or comprehensive test suites targeting Windows desktop applications and drivers.
• Excellent debugging and troubleshooting skills, including the use of tools such as WinDbg, Process Monitor, Windows Performance Analyzer and similar diagnostic tools.

Nice to have

• Experience in reverse engineering, disassembly, or debugging at the kernel/driver level.
• Practical knowledge of functional and regression testing methodologies for desktop applications.
• Familiarity with performance testing techniques (soak, stress, load testing).
• Background in virtualization platforms, data center operations, or VM lifecycle management.
• Experience integrating AI/LLM-based solutions into automation to improve testing efficiency.
