• Coordinate with business teams to define sampling methodologies and prepare representative Golden Datasets for model training and evaluation.
• Work with Data Scientists to define evaluation criteria and business success metrics, including precision, recall, accuracy, and automation rates, where applicable.
• Support model output validation, error analysis, and identification of improvement opportunities.
• Analyse discrepancies between expected and actual AI outputs and coordinate corrective actions with relevant teams.
• Support business acceptance testing and ensure AI solutions satisfy agreed success criteria.

4. Responsible AI, Risk & Governance

• Ensure requirements consider data privacy, security, bias, fairness, explainability, transparency, and appropriate human oversight.
• Work with Data Science, Security, Risk, and Compliance teams to identify, document, and track AI-related risks and mitigating controls.
• Support AI governance and model approval documentation, risk assessments, and auditability, including decision traceability, access controls, logging, and monitoring.
• Capture risks including hallucinations, data leakage, prompt injection, model drift, and unintended agent actions; document guardrails, human review, fallback, and escalation requirements in acceptance criteria.

5. Technical Understanding, API Testing & NFRs

• Analyse existing systems, data structures, and workflows to support AI solution integration.
• Understand and document data schemas, data mappings, JSON, XML/XSD, and API integration requirements.
• Use Postman or similar API testing tools to inspect and validate API requests, responses, and integrations alongside engineering and QA teams.
• Prepare process flow diagrams, data flow diagrams, functional specifications, and technical requirement documentation.
• Define measurable AI/ML and GenAI-specific NFRs with architects and engineers, covering latency, scalability, reliability, security, output quality, robustness, monitoring, explainability, auditability, privacy, and human oversight.
