Manage system and staging testing, including smoke/regression suites and release validation.
Conduct exploratory and usability testing where needed, converting high-value scenarios into automation.
Support and coach Engineers to shift left, improving testability, acceptance criteria, and quality practices.
Monitor and improve quality metrics to guide continuous optimisation (flake rate, coverage, feedback loop efficiency).
Stay current with modern QA tools and practices, adopting only what improves speed, reliability, or developer experience.

Requirements
