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.

As Cyber Security Assurance Lead, you will drive end-to-end EUC security assurance for a transformational Machinery of Government, macOS Developer Device Solution.

Key accountabilities include:

1. Leading security assurance and governance throughout the solution lifecycle (architecture design, through build, deployment & operational support).
2. Development and maintenance of risk management documentation (RMADS, SyOps, DPIAs, threat models, and continuous threat models).
3. Ensuring alignment with assurance frameworks (Government Security Classifications (GSC), NCSC guidance, Cabinet Office requirements, GDPR, ISO27001).
4. Conducting threat and vulnerability assessments for macOS devices, MDM platforms, developer tooling, remote access, and cloud-native infrastructure.
5. Driving secure-by-design practices, working with security architects, engineering DevOps, and testing teams.
6. Interfacing with stakeholders to gain necessary approvals and accreditation.
7. 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:

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

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