Principal SDET

Lead design and development of scalable automated test frameworks for validating microservices, streaming pipelines, and event-driven systems. Build mocking and simulation frameworks that emulate complex upstream services and dependencies (Kafka, market data, order routing, etc.). Integrate test execution with GitLab CI/CD pipelines to enable full automation and parallelized test runs. Enable developers to run complete regression suites locally, independent of shared environments. Collaborate with developers and SDETs to ensure new functionality is covered by comprehensive test suites (functional, regression, performance, reliability). Contribute to framework extensibility and promote reusable testing libraries. Conduct root cause analysis for test failures and production issues, raising risks early to engineering leadership and influencing design decisions. Mentor team members in advanced testing techniques, mock-based architecture validation, and performance measurement.
