- Balance pragmatism with assurance, ensuring proportionate testing within Agile delivery constraints
- Lead the design and evolution of automated test frameworks (UI, API, or service-level)
- Define what should and should not be automated, considering value, maintainability, and risk
- Integrate automated tests into CI/CD pipelines and advise teams on improving feedback cycles
- Evaluate and recommend testing tools, frameworks, and practices to improve effectiveness and efficiency
- Plan, build and execute non-functional testing activities, including performance, accessibility, security, resilience, and interoperability
