• Collaborate closely with front-end (React) and back-end (.NET) developers to identify, reproduce, and resolve UI defects and regression issues early in the development lifecycle.
• Build resilient page objects, maintain UI locator strategies, and handle dynamic UI elements to ensure high test reliability and minimal flakiness.
• Manage UI test suites, bug reports, and quality documentation in Jira.
• Integrate automated Playwright UI test runs into Azure DevOps CI/CD pipelines for automated regression testing on builds.
• Perform functional UI, cross-browser compatibility, and visual regression testing across target platforms.
• Analyze automated test execution results, capture artifacts (trace files, screenshots, videos), and provide actionable reports to the development team.
• Drive continuous improvement of UI testing strategies, design patterns, and test execution speed.
• Stay updated on industry trends in modern JavaScript development and modern UI testing tools.

Qualifications:

• Bachelor's degree in Computer Science, Software Engineering, or a related field (or equivalent practical experience).
• 4+ years of experience in software quality assurance with a heavy focus on UI test automation.
• Strong proficiency in JavaScript (ES6+) and hands-on expertise with Playwright for web UI automation.
• Deep understanding of DOM manipulation, CSS/XPath selectors, shadow DOM, and handling dynamic React UI elements.
• Direct experience testing complex React-based front-end applications.
• Familiarity with web architectures (.NET back-ends) to effectively trace UI issues to integration points.
• Experience integrating Playwright automated UI suites into Azure DevOps CI/CD pipelines.
• Strong knowledge of Jira for defect tracking, sprint planning, and test management.
• Familiarity with Agile development methodologies and modern QA best practices.
• Excellent communication and problem-solving skills with a collaborative, team-oriented mindset.
