AI Central - Unit Test Automation Engineer

Test automation on large enterprise codebases, including code written without testability in mind. • Demonstrable experience putting a validation path onto code with little or no existing coverage: characterization tests, introducing seams, dependency breaking, test-data and fixture strategy. • Deep in at least two of: Java (JUnit 5, Mockito), C#/.NET (xUnit, NUnit), C++, JavaScript/TypeScript (Jest, Selenium, Playwright). • Designing and running regression automation as a managed, repeatable process rather than a set of scripts. • CI integration and quality gates: GitHub Actions, or Jenkins pipelines; coverage instrumentation and static analysis gates. • Practical, current use of an AI coding assistant or coding agent to generate, triage and maintain tests at volume — not tool familiarity, operating experience. Nice To Have Mutation testing. • Contract testing and service virtualization. • Test tooling for mainframe or COBOL estates. • SQL-heavy systems where business logic sits in stored procedures. • Building reusable internal test libraries for other teams to consume.
