Build and execute automated test cases to ensure robust, reliable service pipelines

Perform integration testing across systems and interfaces (APIs, databases, flat files)

Partner with engineering teams on requirements and technical design reviews to bake automation into new features from the start

Evaluate and evolve existing data test automation frameworks

Recommend and implement modern automation tools and techniques

Maintain and improve automated tests within CI/CD pipelines

Champion quality ownership across the team

Enable fast, direct feedback loops on every code submission
