• Improve test reliability, execution speed, and maintainability.
• Identify quality risks and communicate them clearly to engineering and product stakeholders.
• Explore and introduce AI-assisted testing tools and modern automation approaches.
• Support recruitment and onboarding of new automation engineers as the team grows.
   

Required Skills and Experience:

• 5+ years of hands-on QA automation experience, including ownership of an automation codebase.
• Strong experience with Playwright and TypeScript in production-level automation frameworks.
• Solid JavaScript/TypeScript skills for building and maintaining automated tests.
• Experience with Cypress or Selenium may be considered if the overall automation background is strong.
