Integrate secure‑by‑design approaches into technology, engineering, and delivery programmes
Lead and govern architecture reviews across major initiatives, acting as the final authority on security design decisions
Provide authoritative guidance on cloud security, network security, identity & access management, data protection, and secure infrastructure design
Own, maintain, and continuously refresh cybersecurity policies, standards, and governance frameworks
Translate regulatory obligations into actionable technical and architectural controls
Ensure compliance with external frameworks (IEC 62443, NIST CSF, Cyber Fundamentals) and alignment with CRU price control allowances
Monitor and interpret emerging threats, vulnerabilities, and regulatory changes, translating them into strategic and architectural responses
Promote cost consciousness and financial responsibility in cybersecurity decision‑making
Define and evolve the enterprise cyber security architecture strategy, ensuring alignment with business objectives, regulatory obligations, and emerging threat landscapes
Develop, maintain, and communicate a multi‑year Cyber Security Strategy and risk‑driven Cyber Roadmap
