Job Summary:
CaseGuard is a software company that helps various organizations manage their media redaction needs through innovative software solutions. They are seeking a detail-oriented Software Engineer in Test to ensure the quality and reliability of their WPF-based application by developing test cases, performing manual UI testing, and collaborating with developers to build a robust testing culture.
Responsibilities:
• Design, develop, and maintain test cases, integration tests, and end-to-end test suites for a WPF desktop application built with C# and .NET Framework.
• Perform thorough manual UI testing, including exploratory testing to surface edge cases and regressions.
• Automate UI interactions and workflows using desktop automation frameworks (e.g. FlaUI) to build a reliable, repeatable test suite.
• Verify media outputs: frame-accurate redaction checks, golden-file comparisons, and tolerance-based validation of AI detection results across GPU and CPU execution paths.
• Collaborate with developers and product teams to understand feature requirements and define testable acceptance criteria.
• Identify and document bugs with clear reproduction steps, root-cause analysis, and priority assessment; create and track bug tickets through resolution.
• Participate in code reviews to provide input on testability, coverage gaps, and quality standards.
• Contribute to a test-driven development (TDD) culture by writing tests alongside feature development and advocating for testability in design decisions.
• Maintain and improve CI/CD pipeline integration so automated tests run consistently on every build.
Qualifications:
Required:
• Bachelor's degree in Computer Science, Software Engineering, or a related field, or equivalent professional experience.
• 2+ years of experience in a software testing, QA engineering, or SDET role.
• Proficiency in C# and experience with .NET Framework.
• Hands-on experience writing and maintaining unit tests and integration tests using frameworks such as MSTest, NUnit or xUnit.
• Experience performing manual UI testing for desktop or complex GUI applications.
• Familiarity with WPF concepts (data binding, MVVM pattern, control hierarchy) sufficient to navigate and inspect the application under test.
• Strong attention to detail and a methodical approach to reproducing and documenting issues.
• Ability to work independently, prioritize effectively, and collaborate with cross-functional teams.
Preferred:
• Experience automating WPF or Windows desktop UI interactions using tools such as FlaUI.
• Demonstrated practice of test-driven development (TDD) or behavior-driven development (BDD).
• Experience integrating automated test suites into CI/CD pipelines (e.g., GitLab CI, GitHub Actions, Azure DevOps).
• Familiarity with performance profiling and identifying UI responsiveness or rendering bottlenecks in WPF applications.
• Experience with SQL or embedded databases used by desktop applications.
• Knowledge of accessibility testing standards and tools for Windows desktop applications.
• Familiarity with static analysis or code quality tools in the .NET ecosystem.
• Experience introducing test coverage to a large legacy codebase.
