• Lead AI governance, security and Responsible AI by design, ensuring solutions meet regulatory, ethical and organisational standards.
• Provide architectural oversight across delivery teams, ensuring quality and scalability.
• Support pre‑sales and discovery, shaping solution approaches and technical estimates and delivery roadmaps.
• Advise stakeholders on AI feasibility, trade‑offs, risks and long‑term sustainability.
• Build hands‑on prototypes, reference implementations and reusable accelerators to remain close enough to the code to set credible technical direction and unblock delivery teams.

Qualifications Required Skills & Experience
