  • Participate in code reviews and design discussions to help ensure systems are testable and maintainable
  • Work with product owners and engineers to define testable requirements and acceptance criteria

Quality Insights & Reporting
  • Assist in building and maintaining quality dashboards and reporting tools that provide insight into system health and test coverage
  • Analyze test results and communicate findings to development teams to support timely issue resolution
  • Ensure traceability between requirements, implementation, and validation activities

Engineering Documentation & Collaboration
  • Write and maintain documentation for test plans, validation approaches, and test results
  • Collaborate with development and product teams to ensure clear validation strategies and reliable feature delivery
