  • Design, construct, and enhance test automation frameworks for API, UI, contract, integration, and performance testing.
  • Collaborate closely with engineering leads and architects to integrate testability and quality checkpoints within designs and CI/CD pipelines.
  • Guide and train SDET engineers, evaluate their test designs, and promote best practices across teams.
  • Steer cross-functional efforts on non-functional testing, including performance, reliability, security, and chaos engineering.
  • Work alongside DevOps to refine test pipelines for enhanced speed, scalability, and reliability.
  • Analyze complex production issues, conduct root cause investigations, and implement systemic solutions.
  • Innovate by introducing tools, test data solutions, mocks, and dashboards that boost developer productivity and increase release confidence.
