About JT4, LLC
JT4, LLC provides engineering and technical support to multiple western test ranges for the U.S. Air Force and Navy under the Joint Range Technical Services Contract (J-Tech II). Our mission is to develop and maintain realistic integrated test and training environments, preparing the nation's war-fighting aircraft, weapons systems, and aircrews for today's missions and tomorrow's global challenges.
About the Role
The System Administrator serves as a critical operator within the Security Operations Center (SOC) and Mission Control Rooms (MCRs) at the Ridley Mission Control Center (RMCC). In this real-time mission support environment, you will operate, maintain, and administer complex flight testing systems that enable engineers to monitor mission data at near real-time.
Your day-to-day involves managing a diverse infrastructure including Active Directory Domain Servers, Log Auditing Workstations, Assured Compliance Assessment Solution (ACAS) systems, and Network Attached Storage (NAS). You will ensure the stability of enterprise-level Cisco and Juniper switches, Dell PowerEdge servers, and diskless Dell Precision workstations. Beyond technical administration, you will handle media management, track inventory, and serve as the primary point of contact for problem reporting and system upgrades.
This role demands adaptability in a high-pressure, dynamic setting. You may be required to work long hours, including very early mornings or late evenings, to support continuous operations. Success in this position requires a team player who is eager to learn, share knowledge, and collaborate with other system administrators to meet strict security directives and customer needs.

We are seeking individuals who demonstrate a successful adaptation to demanding environments and possess strong verbal and written communication skills.
