• Non-deterministic LLM outputs
• Hallucinations and edge cases
• Multi-step agent decision-making

• Design and manage evaluation systems:

• Golden datasets
• Benchmarking pipelines (accuracy, latency, reliability)

• Automate testing within CI/CD pipelines for model updates, prompt changes, and tool integrations
• Implement observability and telemetry to enable traceability, monitoring, and audit readiness
• Collaborate cross-functionally with ML, MLOps, Product, and Security teams to define quality gates and release criteria
• Track and report quality KPIs, including test coverage, defect leakage, and system reliability
• Drive root-cause analysis and continuous improvement across the AI testing lifecycle
