  • Significant experience leading security teams within large, complex organisations.
  • Strong background in Platform Security, Security Architecture, or Security Engineering.
  • Experience securing hybrid environments across on-premises infrastructure, public cloud, and workplace technologies.
  • Deep understanding of Azure, GCP, Kubernetes, OpenShift, VMware, CI/CD security, software supply chain security, identity and access management, and Zero Trust principles.
  • Proven ability to translate technical risks into business outcomes and influence senior stakeholders.
  • Experience managing large-scale security programmes, budgets, and organisational change.
  • AI, automation, and platform-led security experience is highly desirable.
  • Relevant certifications such as CISSP, CISM, SABSA, TOGAF, or CRISC are advantageous.
