Own test planning, test case creation, maintenance, and traceability for assigned features. Track QA status across development, execute manual and automated tests, document results, write and improve test plans, participate in sprint ceremonies, identify coverage gaps, contribute lightweight automation, and use AI-assisted tools to accelerate test case generation and analysis.

Build and maintain automated API, integration, and end-to-end test suites; investigate complex defects by reading logs and tracing execution; develop tooling for test data and environments; integrate tests into CI/CD; evolve automation architecture and serve as the technical QA resource during triage.
