A Cyber Security Assurance Lead, “a mini CISO,” is sought to join a specialist End User Compute (EUC) IT services provider, leading the modernisation of secure digital workplaces with Zero Trust and next-gen security principles for high-profile Central Government departments—hence the need for current SC clearance.

• Ensuring alignment with assurance frameworks (Government Security Classifications (GSC), NCSC guidance, Cabinet Office requirements, GDPR, ISO27001).
• Conducting threat and vulnerability assessments for macOS devices, MDM platforms, developer tooling, remote access, and cloud-native infrastructure.
• Driving secure-by-design practices, working with security architects, engineering DevOps, and testing teams.
• Interfacing with stakeholders to gain necessary approvals and accreditation.
• Maintaining assurance registers and contributing to programme-wide risk management & reporting.

We are seeking applications from candidates with a strong understanding of endpoint and device assurance, ideally with macOS and integration with MDM (e.g., Jamf, Intune, Workspace ONE), and:

• Professional certifications such as CISSP, CISM, CCSP, or ISO 27001 Lead Auditor.
• Experience leading security assurance in central government or similar high assurance environments.
• Deep understanding of security assurance frameworks, including NCSC Cloud Security principles, GDS Service Standards, and government accreditation processes.
• Hands-on experience producing RMADS, SyOps, DPIAs, and equivalent artefacts.
• Security tooling for risk assessments, threat modelling, & vulnerability scanning.
• Security Clearance.

Other preferred skills include experience in DevSecOps or agile environments, knowledge of Zero Trust architecture, IAM, and cloud-native security practices.
