• Build capability through coaching, targeted training, practitioner communities and champions networks.

• Work across technical, governance, security and commercial functions to remove recurring adoption blockers.

• Engage with suppliers and technology providers to identify reusable approaches and reduce fragmented tooling.

• Advise where AI adoption should be constrained, paused or stopped due to security, quality or maintainability risks.

Essential Experience

• Strong hands-on experience with agentic AI engineering.

• Experience building agent workflows, selecting models and integrating agents with tools and services.

• Strong prompt engineering and harness engineering experience.

• Experience with AI coding and agent tooling such as Claude Code, GitHub Copilot, Codex, Kiro or MCP.
