Summary

We’re looking for an experienced QA Engineer who ramps up quickly on complex business domains and turns that understanding into clear, risk-based test strategies. You’ll combine strong manual testing skills with proven test case design and automation in .NET (C#) to raise the bar on quality across web, API, and data flows. You’ll partner closely with Product, Engineering, and DevOps to deliver reliable, testable, and observable software continuously.

What You’ll Do

• Translate business processes into tests: Rapidly learn product/domain concepts and map end-to-end workflows into high-value test scenarios and acceptance criteria.
• Design and execute test suites: Build and maintain comprehensive manual and automated tests (UI, API, integration, regression, smoke, and exploratory).
• Build .NET automation: Develop and maintain C# test automation frameworks (e.g., Playwright, Selenium WebDriver, SpecFlow BDD, NUnit/xUnit/MSTest) aligned to SOLID and POM principles.
• Enable CI/CD quality gates: Integrate automated tests into pipelines (e.g., Azure DevOps, GitHub Actions) with parallel runs, test reporting, and flaky-test management.
• Collaborate across disciplines: Work with Product Owners to refine acceptance criteria, with Developers to shift-left quality, and with business users to validate in staging/pre-production environments and in production once deployed.
• Own defect lifecycle: Identify, document, prioritize, and drive resolution of defects with clear reproduction steps, logs, screenshots, and impact.
• Data & API validation: Test APIs, validate payloads and contracts (e.g., via Swagger/OpenAPI), and verify database outcomes (SQL Server).
• Non-functional checks: Contribute to performance baselines (e.g., k6, JMeter), and security test coordination.
• Test strategy & traceability: Maintain risk-based test plans, coverage maps, and traceability to requirements/ACs.
• Mentor & improve: Share best practices, pair on tests, and improve standards for reliability, maintainability, and observability of tests.

Must Have Qualifications

• Software quality assurance experience, including extensive manual testing and test case design.
• Proficiency in building and maintaining automated tests in .NET (C#) for UI and/or API layers.
• Strong understanding of .NET/.NET Core, ASP.NET (MVC/Web API) fundamentals, HTTP, and JSON.
• Hands-on with Selenium and/or Playwright, plus NUnit/xUnit/MSTest; experience.
• Comfortable reading application code, using Visual Studio/Visual Studio Code, debugging tests, and collaborating on testability.
• Experience with Azure DevOps or GitHub for source control, boards/issues, and CI/CD pipelines.
