Experience testing modern .NET (Core/6+) and Angular applications in a full-stack environment. Proficiency with RESTful API testing, including Swagger and Postman, plus backend test validation. Familiarity with CI/CD tools (GitHub Actions, Azure DevOps, Jenkins) and infrastructure-as-code concepts. Comfortable working in Agile/Scrum development environments. Plus: Experience with performance testing (JMeter, k6) or security testing. Responsibilities Design & Develop Automation Frameworks - Build robust, reusable frameworks using tools such as Selenium, Playwright, and xUnit/NUnit. Implement Best Practices - Apply techniques like Page Object Model (POM), data-driven testing, and API mocking. Integrate with CI/CD Pipelines - Collaborate with developers to embed automated tests into GitHub Actions, Azure DevOps, Jenkins, or similar pipelines. Own Quality Across the Lifecycle - Drive functional, regression, and performance testing from initial requirements through production release.
