• Integrate APIs, external tools, plugins and system connectors required for agent operations.
• Develop and execute evaluation approaches for LLMs and agentic systems, including scenario tests, benchmarks and automated pipelines.
• Assess retrieval components, vector databases, memory systems and workflow reliability.
• Apply Responsible AI principles and regulatory expectations to model behaviour, documentation and control standards.
• Partner with data science, engineering, architecture and risk teams to ensure safe and compliant AI deployment.
• Collaborate with other departments' data scientists to understand modelling intent, technical assumptions and workflow logic.
• Contribute to AI/ML proof - of - concept (POC) initiatives to strengthen evaluation practices and support innovation.
