Mid Automation QA Engineer – AI and Innovation Office

Transform quality assurance from a manual bottleneck into an automated accelerator. You’ll build the automated testing infrastructure that enables rapid, safe deployments of AI services and ML models to production. By creating comprehensive unit tests, integration tests, and CI/CD test pipelines, you’ll dramatically reduce manual testing effort while increasing quality and release confidence. Your automation frameworks will protect critical banking flows 24/7, catch regressions before they reach customers, and provide audit-ready evidence of quality—making you essential to both velocity and governance.
