Test Automation Engineer

Our requirements

• 5+ years of commercial experience in test automation with hands-on framework development.
• Strong C#/.NET skills—ability to write, debug, and review production-grade code, not just test harnesses.
• Proficient in JavaScript/TypeScript for test automation.
• Expertise in Playwright (or Selenium with a willingness to transition to Playwright).
• Practical experience with xUnit/NUnit and Vitest/Jest—unit and integration test design.
• CI/CD integration with Azure DevOps (or GitHub Actions).
• SQL (MSSQL/Azure SQL)—test data setup, validation of transformations, and diagnostic queries.
• REST API testing—contract validation, status codes, and authentication flows (JWT/OAuth/Azure AD).
• Highly autonomous—ability to own the automation roadmap end-to-end and set standards for the team.
• Strong Git practices, code review discipline, and clean test code standards.
• Fluent English (B2+) for technical communication.

Your responsibilities

• Own and evolve automated testing processes for the application portfolio—frameworks, standards, tools, and best practices.
• Design and implement test strategies across unit, API, integration, and E2E layers.
• Develop and maintain E2E automation in Playwright for React applications, backend integration/unit tests in xUnit (.NET), and frontend unit tests in Vitest/Jest.
• Integrate automated tests into CI/CD pipelines (Azure DevOps)—PR checks, nightly runs, pre-release gates, and post-deploy validation with parallel/sharded execution.
• Promote best practices in testing: testability, coverage strategy, meaningful assertions, test data management, and clean test code.
• Validate data flows across Azure SQL, ODS, and DWH layers; design data-driven scenarios and manage test data.
• Drive root-cause analysis, flaky test management, and reliability improvements; publish quality metrics and test artifacts for stakeholders.
• Collaborate with developers on acceptance criteria and test coverage; review test code in PRs and mentor on testability.
• Support UAT coordination—prepare environments, verify business scenarios, and document results.
