  • 6+ years of experience supporting enterprise network infrastructure in a DoD, federal, or similarly regulated environment.
  • Strong hands-on experience configuring, maintaining, troubleshooting, and supporting lifecycle management for Juniper and Cisco network devices.
  • Experience applying and maintaining DISA STIG compliance across network devices.
