Job Description:

Security Clearance required. This role is based in Central London with hybrid working arrangements. It is a 6+ month contract.

We are seeking a Cyber Security Assurance Lead, often referred to as a “mini CISO,” to join a specialist End User Compute (EUC) IT services provider. The role involves leading the modernization of secure digital workplaces using Zero Trust and next-generation security principles for high-profile Central Government departments, hence the requirement for current SC clearance.

As the Cyber Security Assurance Lead, you will oversee end-to-end EUC security assurance for a transformational Machinery of Government project involving macOS Developer Device Solutions.

Key responsibilities include:
  • Leading security assurance and governance throughout the solution lifecycle, including architecture design, build, deployment, and operational support.
  • Developing and maintaining risk management documentation such as RMADS, SyOps, DPIAs, threat models, and continuous threat assessments.
  • Ensuring compliance with assurance frameworks like GSC, NCSC guidance, Cabinet Office requirements, GDPR, and ISO27001.
  • Conducting threat and vulnerability assessments for macOS devices, MDM platforms, developer tooling, remote access, and cloud-native infrastructure.
  • Promoting secure-by-design practices in collaboration with security architects, engineering, DevOps, and testing teams.
  • Engaging with stakeholders to obtain necessary approvals and certifications.
  • Maintaining assurance registers and contributing to program-wide risk management and reporting.

Ideal candidates will have a strong understanding of endpoint and device assurance, especially with macOS and MDM solutions such as Jamf, Intune, or Workspace ONE. Required qualifications include:

  • Professional certifications like CISSP, CISM, CCSP, or ISO 27001 Lead Auditor.
  • Experience leading security assurance in central government or similar high-assurance environments.
  • Deep knowledge of security assurance frameworks, including NCSC Cloud Security principles, GDS Service Standards, and government accreditation processes.
  • Hands-on experience producing RMADS, SyOps, DPIAs, and similar artifacts.
  • Proficiency with security tools for risk assessments, threat modeling, and vulnerability scanning.
  • Current Security Clearance.

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