About the role

Key responsibilities & impact

Test Automation: Design, build, and maintain automated test suites for C# backend services (unit, integration, and API-level tests). Build and maintain automated UI and end-to-end tests for our React frontend. Select and champion appropriate testing frameworks and tooling. Integrate automated tests into CI/CD pipelines to support continuous delivery. Maintain test coverage metrics and report on quality trends over time.
Manual Testing: Write and maintain clear, structured manual test scripts and test plans. Execute manual exploratory and regression testing across features and releases. Document defects clearly with reproducible steps, expected vs. actual outcomes, and supporting evidence. Collaborate with developers and product stakeholders on acceptance criteria and definition of done.
Quality & Process: Introduce and embed QA best practices across the engineering team. Participate in sprint planning, refinement, and review sessions as the QA voice. Work with developers to shift testing left – catching issues earlier in the development cycle. Maintain and improve test documentation, including regression libraries and test data management.
