Role SummaryYou will represent the Security Architecture team across our enterprise architecture and technology community, shaping how security is designed into everything we build including the AI systems now reaching production. This is a senior, influence-led role. You will prioritise the strategic concepts and capability sets that matter most, align security to the architecture process and the NIST framework, and advance technology modernisation and defense-in-depth across multiple clouds and on Prem. You will set direction for a substantial security technology stack including: cloud security posture and workload protection, endpoint detection and response, SIEM, secrets and privileged access management, data protection, application security and perimeter defense and make strategic decisions on the future of the technology stack.What will you do?
Partner with global domain architects to review enterprise architecture patterns and guardrails, ensuring security is designed in rather than retrofitted. Evaluate and recommend emerging technologies, providing technical and thought leadership through proofs of concept and business cases that demonstrate value. Represent security technology and capability strategy at senior executive forums and enterprise technology review boards. Provide architecture and design expertise on enterprise projects and security initiatives, including cross-domain functions, and certify domains in line with architecture governance. Lead the strategic evolution of security capabilities with a zero-trust-first approach, working alongside delivery teams. Define the security architecture for AI adoption covering AI and agentic systems, the data that feeds them, and the platforms that host them. This includes model and agent governance, AI security posture management, data-classification controls for training and inference, guardrails against prompt injection and model misuse, and secure-by-design patterns for AI-enabled products. Set a modernised approach to security tooling, services and capability sets, focused on technical feasibility across emerging technologies, controls and functions. Drive multi-cloud consistency, ensuring controls, telemetry and posture management extend uniformly across all cloud providers rather than clustering around the best-covered one.What will you need to succeed?
