Validate backend and background processes through database queries and log analysis.
Actively detect, debug, and eliminate flaky tests, ensuring stable and trustworthy pipelines.
Handle complex asynchronous and dynamic behaviors using robust synchronization strategies.
Requirements
5+ years of strong C# development experience, with a developer-first mindset and ability to build complex, maintainable automation code.
