About the Role:

Crusoe is seeking a Security Engineer to join the Security Engineering team as the primary driver for implementing security defaults and endpoint visibility. This is a strategic, architectural position focused on building secure-by-default endpoints that protect the organization as it scales. You will be responsible for security architecture, endpoint visibility, and maintaining our security posture across a rapidly growing global fleet of macOS, Windows, iOS, and Android devices. This role involves cross-functional partnership with Security and People Operations, with genuine scope to shape how Crusoe manages and secures endpoints. This role is onsite in San Francisco, CA, Sunnyvale, CA or Denver CO.

What You'll Be Working On:

• Administer and continuously improve Jamf and Microsoft Intune environments across all managed device types: macOS, Windows, iOS, and Android; maintain configuration profiles, compliance policies, app deployment packages, and OS update enforcement across all platforms.

• Build and maintain automated enrollment workflows including Apple Business Manager (ABM) and Windows Autopilot for zero-touch provisioning at scale.

• Own a structured patch management program with clear SLAs for OS and application updates across all device platforms.

• Define and enforce device compliance baselines aligned with Crusoe security standards and frameworks including CIS Benchmarks and SOC 2; integrate MDM telemetry with EDR and SIEM tooling for compliance drift visibility and proactive remediation.
