The Role
The QA Engineer is responsible for validating virtualised services to ensure they are functionally accurate, reliable, deterministic, and fit for SIT testing. The role ensures virtual services behave consistently with real downstream systems, including negative and error scenarios, and are fully operationalised for test teams.
