- Analyze test results and drive quality improvements, close coverage gaps proactively
- Collaborate with Engineering, QA, and DevOps to improve system reliability and release confidence
- Mentor team members through code reviews, pairing, and knowledge sharing
- Continuously improve testing processes, frameworks, and tooling
