Enterprise-level administration and support for macOS and Windows, including imaging, deployment, configuration management, and security baselines.
Experience with endpoint management and automation platforms such as Ivanti, KACE, Microsoft Intune, and JAMF.
Ability to manage and troubleshoot identity and access management — Microsoft Entra ID / Active Directory, MFA, role-based access controls, and AWS-integrated identity solutions.
Ability to diagnose authentication, connectivity, and endpoint performance issues by analyzing system logs, Event Viewer, macOS Console, and monitoring tools.
Experience coordinating cross-team incident response with Service Desk, Network Operations, and Cybersecurity teams.
