Integrate automation deeply into CI/CD pipelines using Jenkins and/or GitHub Actions
Enforce mandatory quality gates, blocking releases on automation or sanity failures
Monitor automation executions, analyze failures, and drive root-cause resolution
Conduct automation code reviews to ensure consistency, reusability, and maintainability
Collaborate during design and story elaboration to define acceptance criteria and risk coverage
Mentor QA and engineering teams on automation frameworks, tooling, and best practices
Contribute to automation metrics, reporting, and continuous improvement initiatives

Even better if you have

Use AI agents or tools to perform day-to-day activities or to test AI-powered features.
Familiarity with visual regression testing, cross-browser testing, and performance validation
Experience designing or contributing to automation metrics and quality dashboards
Exposure to cloud-native, large-scale SaaS platforms
Experience mentoring teams and driving the adoption of quality standards across multiple squads

You will thrive in this role if

Believe quality is a shared responsibility across Engineering, QA, and Product
