• Promoting secure-by-design practices in collaboration with security architects, engineering, DevOps, and testing teams.
• Engaging with stakeholders to secure necessary approvals and accreditation.
• Maintaining assurance registers and contributing to program-wide risk management and reporting.

We are seeking candidates with a strong understanding of endpoint and device assurance, ideally with experience in macOS and MDM platforms such as Jamf, Intune, or Workspace ONE, and with:
