• Execute, analyze, maintain, and improve existing Playwright end-to-end test suites;
• Investigate and resolve flaky automated tests while maintaining stable regression coverage;
• Extend automated tests where appropriate to improve product quality and release confidence;
• Identify quality risks early and proactively propose improvements to QA processes;
• Verify complex integrations with third-party systems;

• Communicate quality risks, testing results, and release readiness clearly to stakeholders;
• Work autonomously while taking full ownership of the QA process.

• 5+ years of commercial experience in software testing;
• Strong hands-on experience in manual testing of modern web applications;
• Solid commercial experience with Playwright for end-to-end test automation;
