• Design, develop, and maintain scalable and reliable automated test frameworks across UI, API, and performance layers. • Build and execute API, UI, and performance tests using automation frameworks like Selenium, Playwright, Appium, Rest Assured, or JMeter. • Apply BDD (e.g., Cucumber) or TDD approaches with maintainable and reusable test design patterns • Integrate automated testing into CI/CD pipelines, ensuring fast and reliable feedback • Improve test reliability by reducing flakiness and optimizing execution time • Enable parallel test execution and environment scalability • Ensure end-to-end test coverage by creating and maintaining comprehensive test cases, test plans, and test scripts. • Perform exploratory and risk-based testing to uncover complex defects and conduct root cause analysis and deep debugging of failures and defects • Analyze logs, data, and system behavior to identify hidden quality risks • Validate end-to-end workflows and complex integrations • Identify, document, and track defects using JIRA, Azure DevOps, or similar tools. • Collaborate with developers to improve testability and code quality • Write clean, maintainable, and scalable automation code following engineering best practices • Perform database validation using SQL/NoSQL

• Design and develop automated test scripts covering core business logic, UI flows, and API services • Define testing specifics and acceptance criteria based on product goals • Configure and maintain the automation environment (IDEs, CLI tools, CI/CD runners) to keep test execution stable and efficient • Take ownership of quality readiness for team-level deliverables, clearly communicating release risks, trade-offs, and mitigation plans • Verify that implemented features meet defined scenarios and performance standards, and share actionable feedback directly with developers • Contribute to technical documentation for test plans and automation frameworks, keeping it current and useful for the broader team.

• 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.
