Network Administrator

GDIT has an exciting opportunity to support the Security Assistance Group – Ukraine (SAG-U) as a member of our Enterprise Mission Information Technology Services (EMITS) program supporting U.S. Army Europe and Africa’s (USAREUR-AF) mission in Wiesbaden, Germany.

The Network Administrator is a member of the J63 Network Operations (NetOps) team responsible for sustaining day-to-day network operations across SAG-U enclaves. This role focuses on monitoring, troubleshooting, and maintaining network infrastructure and services, executing approved configuration changes, and supporting operational readiness for mission users.

MEANINGFUL WORK AND PERSONAL IMPACT

As a Network Administrator at GDIT, you will directly enable mission communications by keeping critical network services available, secure, and recoverable. Your work supports operational tempo by reducing outages, improving mean time to restore service, and ensuring network changes are implemented through disciplined governance.

• Monitor network health, respond to incidents, and perform troubleshooting and root cause analysis for network degradation or outages.
• Implement approved network changes in accordance with Change Management and CAB processes, including documenting implementation results and closure evidence.

• Maintain network documentation including device inventories, port maps, rack layouts, cable management updates, and as-built diagrams sufficient for sustainment and audit readiness.
• Coordinate with Cybersecurity personnel to support secure configurations, traffic reviews, anomaly response, and basic compliance support (for example STIG-aligned settings and evidence collection when directed).
• Support VoIP/VTC network connectivity troubleshooting and collaborate with stakeholders to restore service quickly during events or VIP mission requirements.
• Coordinate with external organizations (NEC, DISA, partners, vendors as applicable) to resolve issues impacting mission connectivity and service delivery.
• Assist with procurement and sustainment support as required (initial bills of material inputs, tracking replacements, and validating received equipment against needs).
• Participate in on-call or after-hours support during maintenance windows, outages, or mission surges (including occasional weekend or holiday coverage).

• Experience performing cable management and routine network cabinet maintenance.
• Ability to follow governance and documentation standards, including producing clear updates for tickets, change records, and as-built documentation.
• Ability to work independently and in a team-oriented environment, escalate appropriately, and maintain operational discipline under time pressure.
