The Head of Security Architecture leads the global enterprise security design and architecture across on‑prem and cloud environments, coordinating a team that includes Senior Enterprise Security Architects, a Security Roadmap Program Manager, and Security Process Experts. Reporting to the CSO, this role translates risk insights into secure‑by‑design patterns, standards, and roadmaps, enabling secure transformation while balancing risk, agility, and cost. Without this role, security architecture could fragment, risk would rise, and consistent controls would be hard to sustain across business units and technologies.
