We will count on you to:

• Lead Quality Engineering across multiple AI delivery pods and establish consistent, risk-based quality standards.
• Partner with Product and Engineering to define test strategy, acceptance criteria, UAT approach, quality risks, and release-readiness criteria.
• Ensure appropriate coverage across functional, integration, end-to-end, non-functional, AI-specific, and business acceptance testing.
• Define testing and evaluation approaches for LLM, RAG, agentic, and AI-enabled solutions, including grounding, hallucination risk, regression, tool calling, workflow behaviour, and non-deterministic outputs.
• Establish appropriate AI evaluation datasets, test harnesses, baselines, thresholds, and regression approaches.
• Guide and, where needed, implement reusable automation across web, APIs, backend services, integrations, asynchronous workflows, and AI components.
• Ensure products are ready for UAT, with appropriate test evidence, environments, test data, defect status, entry/exit criteria, and known risks.
• Provide Pod Leads and programme leadership with clear quality metrics, risks, defect trends, AI evaluation results, UAT readiness, and release-readiness reporting.
• Conduct quality reviews across pods and identify gaps in testing, testability, observability, or quality evidence.
• Use production incidents, escaped defects, telemetry, and user feedback to continuously improve quality approaches.
• Coach engineers and delivery teams to strengthen shared ownership of quality across the lifecycle.
