Design, develop, and maintain automation frameworks (UI, API, and mobile). Write and execute complex automated test scripts using tools such as Selenium, Cypress, Appium, or similar. Perform hands-on testing (functional, regression, integration, performance, security) when needed to ensure release readiness. Conduct API and backend testing (Postman, RestAssured, SQL queries, stored procedures validation). Investigate production issues, perform root cause analysis, and propose permanent fixes. Optimize test execution pipelines within CI/CD (Jenkins, Azure DevOps, GitLab CI). Ensure non-functional testing (performance, load, security) is embedded into delivery cycles. Develop reusable test components and share them across teams. Act as the technical escalation point for QA team members, guiding them in troubleshooting and debugging. Design Consistency: Adherence to design systems and usability standards across products. User Satisfaction: Improvement in customer feedback, usability scores, or NPS. Delivery: % of design deliverables completed on time and integrated into product releases.
