• Own end-to-end quality assurance, including test strategy, test case design, and acceptance validation. • Perform manual and exploratory testing of new features in fast-changing (greenfield) environments where early automation is not optimal. • Gradually design, build, and maintain automated test suites for stabilized functionality, including UI, API, integration, and E2E tests. • Define and maintain a regression testing approach, starting with manual smoke testing and evolving into automated regression coverage focused on high-risk areas (auth, number purchase, porting, billing). • Conduct API and integration testing across external systems such as carrier platforms, ServiceNow, billing APIs, and Cognito authentication flows. • Integrate automated testing into CI/CD pipelines and ensure continuous quality validation. • Collaborate with Business Analysts to clarify and validate acceptance criteria. • Log, track, and manage defects through resolution. • Support stabilization phases and UAT cycles to ensure production readiness.
