About the role

  • Serve in a dual-capacity role that balances high-level network design and architecture responsibilities with day-to-day operational support and device configuration across enterprise environments.
  • Administer and maintain a multi-site enterprise network, including the configuration and lifecycle management of routers, switches, firewalls, VPNs, wireless infrastructure, and load balancing technologies.
  • Develop scalable and resilient network architectures that support high availability, fault tolerance, and future growth, with an emphasis on alignment with DOE enterprise IT strategy and security policies.
  • Engineer and support complex routing strategies involving protocols such as EIGRP, OSPF, and BGP; ensure optimal route redistribution, convergence, and path selection across hybrid connectivity models including DMVPN and MPLS.
  • Implement and manage next-generation firewall platforms (e.g., Palo Alto), including high availability configuration, SSL decryption, policy optimization, IDS/IPS system configurations, and integration with cloud and on-premises security architectures.
  • Design, deploy, and manage hybrid network topologies within Microsoft Azure, including Virtual Networks (VNets), ExpressRoute, peering, NAT Gateway, and firewall solutions to ensure secure and performant cross-premise connectivity.
  • Support the implementation and management of NAC solutions such as Cisco ISE, including potential integration with Microsoft Intune to enforce endpoint compliance and identity-based access control.
  • Lead and execute infrastructure modernization initiatives, including the planning, implementation, and validation of new networking technologies or the re-architecture of existing environments.
  • Leverage network performance tools such as Catalyst Center, SolarWinds and Azure Network Watcher to monitor availability, perform root cause analysis, and implement performance enhancements.
  • Maintain accurate technical documentation including topology diagrams, configuration baselines, IP address management, and change control records to support audit readiness and operational continuity.
  • Partner with adjacent IT disciplines—including cloud, systems, security—to deliver integrated solutions; provide mentorship and technical leadership to junior technical staff as needed.
