STRONGLY DESIRABLE * Retrieval-augmented generation (RAG) - grounding responses in trusted organisational knowledge. * Evaluation (evals) - defining, measuring, and improving the quality and reliability of AI and agent behaviour. * Guardrails and safety - input/output filtering, hallucination mitigation, control over autonomous actions, and responsible-AI practices. * Prompt and context design, memory, and other techniques for shaping reliable model and agent behaviour., * Experience building customer-facing AI - delivering AI systems that real external customers interact with, and handling the extra bar for safety, trust, and polish that comes with it. * Exposure to agent-driven and AI-generated UI - interfaces that agents render, drive, or adapt dynamically. All Senior Leaders are expected to demonstrate a clear set of leadership behaviours to create an environment for colleagues to thrive and deliver to a consistently excellent standard. The four LEAD behaviours are: L - Listen and be authentic, E - Energise and inspire, A - Align across the enterprise, D - Develop others. ## Description select between different models, agent patterns, and architectures as the problem demands. * Leading architecture across teams - setting technical direction that other engineers build on. * An insatiable pull toward new and emerging technology - you keep up with
