## Description

As a Network Engineer on our team, you'll support the sustainment, maintenance, and operational readiness of Cisco-based network infrastructure within a Department of Defense (DoD) engineering laboratory environment. You'll work alongside network engineers and technical teams to maintain lab systems, perform Information Assurance Vulnerability Management (IAVM) activities, implement security updates, support software upgrades, and ensure network devices remain compliant with applicable DoD security requirements.

You'll play an important role in supporting accelerated vulnerability remediation timelines by coordinating patching activities, conducting post-upgrade validation, troubleshooting network issues, and maintaining accurate technical documentation. This position emphasizes hands-on network administration, system sustainment, and technical collaboration to ensure the laboratory remains secure, reliable, and ready to support engineering and testing activities.
