• Design and deploy agentic systems into live business workflows.
• Drive the automation of complex, judgement-heavy business processes.
• Lead the delivery of AI solutions from concept through to production deployment.
• Ensure AI solutions are scalable, reliable, and capable of operating effectively within live environments.
Governance, Risk & Evaluation
• Establish frameworks for AI evaluation, monitoring, and secure release management.
• Design for AI failure modes, operational risk, and system resilience.
• Ensure AI solutions are deployed responsibly and aligned with organisational risk requirements.
• Develop appropriate controls, testing approaches, and governance processes to support production deployment at scale.
Experience & qualifications

• Demonstrated ability to own and deliver complex AI initiatives from architecture through deployment.
Personal Attributes
• Commercial, pragmatic, and outcomes-focused.
• Comfortable operating in a fast-paced and evolving environment.
• Hands-on and technically credible, with a willingness to remain close to architecture, build, and delivery.
