• Driving secure-by-design practices, collaborating with security architects, engineering DevOps, and testing teams.
• Interfacing with stakeholders to gain necessary approvals and accreditation.

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:
