UT Government is looking to add an ePACS System Administrator to their team supporting a federal facility in Washington, DC. This is a full-time, five (5) day per week onsite position requiring an active or eligible government clearance.

The ePACS (Electronic Physical Access Control System) System Administrator is responsible for the day-to-day administration, maintenance, and optimization of the integrated security infrastructure at a federal facility, including Active Directory, network infrastructure (HP switches), the Gallagher Access Control System (ACS), and the Avigilon Unity Video Management System (VMS). This role requires a strong, hands-on IT foundation in enterprise systems and network administration.

Prior experience with ACS/VMS platforms is a plus but not required — UT will provide platform-specific training to the right candidate. This position may also be responsible for the day-to-day oversight and mentorship of a local technician.

• Administer and maintain Active Directory, Group Policy, DNS, and AD Certificate Authority (AD CA) services in support of PIV credentialing and the physical security environment.
• Manage user accounts, permissions, and group policy objects in accordance with federal security requirements and organizational baselines.
• Apply system and security patches, monitor server health, and ensure planned maintenance is scheduled to avoid disruption to government operations.
• Maintain accurate system documentation, configuration records, and standard operating procedures.

• Configure, maintain, and troubleshoot HP (and Cisco) network switches supporting the security infrastructure, including CLI-based configuration.
• Design, implement, and troubleshoot VLANs, static and dynamic routing, and network segmentation in support of secure system operations.
• Monitor network performance and proactively identify, diagnose, and resolve connectivity and infrastructure issues.

• Administer and support the Gallagher Access Control System, including credential management, door/panel/reader configuration, and system integrations (training provided).
• Administer and support the Avigilon Unity Video Management System, including camera and recording configuration, health monitoring, and troubleshooting (training provided).
• Program system events, notifications, and alerts, including door access denials, forced-door alerts, and related security notifications.
• Support integration of the ACS/VMS environment with related systems such as PIV/USAccess, intrusion detection, and notification/SMTP services.

• May provide day-to-day direction, task assignment, and mentorship to an onsite local technician.
• Serve as the primary point of contact for ePACS-related issues, coordinating with government personnel, contractors, and outside agencies as needed.
• Provide basic end-user training on day-to-day system operations as needed.
• Collaborate with UT technical teams and government stakeholders to resolve complex issues and support broader physical security goals.

• 5+ years of hands‑on IT experience, including Active Directory, Group Policy, DNS, and AD Certificate Authority / PIV-related services.
• Solid working knowledge of network configuration and troubleshooting,…
