• Maintain trusted knowledge bases and ensure source‑grounded AI responses.

AI Platform & Integration

• Integrate AI applications with enterprise systems, APIs, databases and internal platforms.
• Develop secure tool‑calling capabilities and support deployment into production.
• Monitor and optimise AI application performance.

Model Quality & Governance

• Design evaluation frameworks to measure response quality, retrieval accuracy and hallucination risks.
• Optimise prompts, guardrails and model performance.
• Support governance, version control and human‑in‑the‑loop review processes.

Stakeholder Collaboration

• Partner with product, engineering and business teams to deliver AI solutions.
• Support demonstrations, UAT, production rollout and technical documentation.
• Communicate technical concepts clearly to technical and non‑technical stakeholders.
