• MDM/Endpoint Management: 3-6 years of experience with Jamf/Kandji and Microsoft Intune (Autopilot, Compliance Policies, App Protection).

• Independent Engineering: A "Security-First" mindset and proven ability to drive R&D initiatives from planning through implementation independently, with a focus on automating security controls.

• Scripting & Automation: Proficiency in Bash, Python, or PowerShell for device policy automation, packaging, and remediation.

• Infrastructure Knowledge: Strong understanding of certificate infrastructure (SCEP, PKCS) and experience with Absolute for Windows persistence.

• Strong documentation habits, ownership mindset, and ability to communicate technical policies to non-technical stakeholders.

• Bachelor’s degree in IT, Computer Science, or equivalent practical experience.

• OSQuery and CrowdStrike expertise , demonstrable experience leveraging OSQuery for endpoint visibility and administering CrowdStrike for threat detection and response; these are foundational to our security visibility and enforcement strategy.
