• Manage endpoints using Microsoft Endpoint Manager, including Microsoft Intune policy administration and Windows Autopilot deployments.

• Maintain software and operating system patch cadence across the managed endpoint fleet.

Identity and Access Administration

• Manage user accounts and directory services including Active Directory, Microsoft Entra ID, and Group Policy.

• Support secure access protocols including conditional access policy administration and multifactor authentication enrollment.

Security Operations Support

• Monitor and triage security alerts in Microsoft Defender and Microsoft Sentinel, escalating confirmed incidents to the security and compliance function.

• Execute vulnerability remediation based on Nessus scan results, including system hardening, patching, and verification of closure.

• Administer email security tooling including Proofpoint and secure mail flow policies; analyze email headers in support of phishing investigations.

• Support phishing simulation campaigns and security awareness initiatives run by the security and compliance function.

• Contribute evidence and system configuration detail in support of CMMC and SOC 2 audit cycles.

Support, Automation, and Continuity

• Provide advanced technical support and resolve escalated IT tickets with professionalism and efficiency.

• Write and maintain PowerShell and Python scripts to automate repetitive administrative tasks and reporting.

• Assist in disaster recovery planning, backup strategy, and restoration testing.

• Write and maintain technical documentation and internal knowledge base articles for procedures owned by this role.

• Participate in a bi-weekly on-call rotation to provide after-hours support as needed.
