Network Administrator Work in Arlington
The largest network team in Arlington sits at GM Financial's Arlington AOC I site, 4001 Embarcadero, where the auto lender posts global network engineering, systems engineering and site reliability roles. North Arlington holds the rest of the in-house demand: Texas Health Resources' corporate headquarters at 612 E Lamar Blvd and Arlington ISD's administration at 690 E Lamar Blvd both run networks that reach far beyond the building, to hospitals across North Texas and to every campus in the district.
The MSP side is centered on Custom Information Services at 1201 N Watson Rd, which lists a network admin supervisor role in Arlington and NOC engineer roles covering DFW clients. MSP network work means many small environments instead of one large one, plus after-hours maintenance windows and drives to client sites.

How to Become a Network Administrator in Arlington
BLS reports that most network administrators hold a bachelor's degree, though some employers accept a certificate or associate degree. Locally, Tarrant County College Southeast Campus, 2100 Southeast Pkwy, offers the IT and Cybersecurity associate degree, and UT Arlington's College of Engineering covers the four-year route. Custom Information Services asks its network admin supervisor for an associate degree, five or more years in network administration and MCSA or MCSE, with Cisco or VMware a plus. Texas does not license network administrators.
What the Job Involves
A network administrator configures and monitors switches, routers, firewalls and wireless access points, manages VLANs and VPNs, troubleshoots outages, applies patches, audits systems and keeps documentation current for the help desk. Expect maintenance windows at night and on weekends, plus on-call rotations, since changes are made when users are offline.
Skills Employers Look For
- TCP/IP, DNS, DHCP and subnetting
- Cisco or comparable switch and router configuration
- Firewall, VPN and VLAN management
- Windows Server administration, often with MCSA or MCSE
- VMware and virtualization basics
- Network monitoring and clear documentation
- Calm troubleshooting during outages
Career Path and Advancement
Most Arlington network admins start on a help desk or as a Level 2 technician, then move into network administration with Network+ or CCNA. From there the ladder runs to supervisor, as at Custom Information Services, or to network and systems engineering, as at GM Financial's Arlington site, with cloud and cybersecurity roles as the next step up.
