Responsibilities:

• Define test plans, risk matrices, and coverage strategies for new features and releases
• Establish QA standards, guidelines, and best practices across the team
• Partner with product and engineering to identify testability gaps early
• Own end-to-end release quality sign-off process
• Author and maintain automated UI, integration, and regression tests using Playwright
• Write clean, maintainable test code in C# within .NET test frameworks
• Integrate automated suites into CI/CD pipelines (Azure DevOps, GitHub Actions)
• Perform exploratory, functional, and performance testing as needed
• Lead root cause analysis for complex or recurring defects
• Recommend and document the best fix approach — not just report the bug
• Collaborate with developers to validate fixes and prevent regression
• Maintain a defect classification and prioritization framework
• Track quality metrics: defect escape rate, test coverage, and flake rate
• Drive process improvements through retrospectives and data
• Mentor junior QA team members on strategy and automation
• Evaluate and adopt new testing tools and frameworks

Requirements:

• 5+ years of software quality engineering experience in enterprise environments
• Strong hands-on experience with Playwright for end-to-end and cross-browser automation
• Proficiency writing test code in C# within .NET (NUnit, xUnit, or MSTest)
• Demonstrated ability to build and own a QA strategy from scratch — not just follow one
• Experience with CI/CD pipelines and integrating automated tests into build workflows
• Solid understanding of RESTful APIs and ability to perform API-level testing
• Strong analytical skills to diagnose defects at the system level and guide resolution
• Experience with Agile/Scrum methodologies and sprint-based delivery
• US Citizenship is required
• Experience with Azure DevOps or GitHub Actions for pipeline automation
• Familiarity with SQL for data validation and backend testing
• Knowledge of performance testing tools such as k6, JMeter, or similar
• Experience with Docker or containerized test environments
• ISTQB certification or equivalent formal QA training
