• Manage and optimize routing and switching environments (SD-WAN, BGP, OSPF, EIGRP, VLANs, STP, HSRP/VRRP).
• Configure and support firewalls, VPNs, and network security controls enforcing CUI boundary segmentation.
• Design and maintain network architecture supporting CUI enclaves, including access control, encryption in transit, and audit logging per NIST 800-171 / DFARS 252.204-7012.
• Lead network upgrades, migrations, and infrastructure projects with attention to compliance boundary impact.
• Support and troubleshoot network performance issues and outages (root cause analysis).
• Monitor network health using tools like SolarWinds / ThousandEyes (or similar), including compliance-relevant traffic visibility and alerting.
• Maintain network documentation: diagrams, IP schema, standards, runbooks, and System Security Plan (SSP) network artifacts.
