• Design, implement, and maintain a robust, scalable, and cross-platform automated testing framework for agent functionality (e.g., data collection, remote execution, inter-process communication).
• Develop high-quality, reliable, and reusable automation tests (component, integration, end-to-end) primarily in C# (.NET) to validate agent behavior on Windows, Linux, and macOS.
• Work closely with development engineers to understand low-level system interactions and ensure test coverage for platform-specific components (e.g., Win32 API, Linux syscalls, macOS IOKit/Launchd).
• Integrate test suites into the CI/CD pipeline using Azure DevOps to ensure rapid and high-quality releases.
• Configure and maintain the multi-platform test environment, including provisioning virtual machines, containers, and physical end-points for accurate testing.
• Monitor test execution, analyze results, report defects, and collaborate with developers to ensure timely resolution.
