• Support Cisco ISE administration, firewall policies, network segmentation, ACLs, VLANs, VPNs, authentication, authorization, policy enforcement, and device access control.
• Use CLI-based tools to diagnose routing, switching, MTU, latency, throughput, and connectivity issues across network devices and Linux hosts.
• Support inter-site provisioning and lifecycle activities, including maintenance, upgrades, technology refresh, documentation, diagrams, standards, and operational procedures.
• Partner with systems, cybersecurity, and infrastructure teams to maintain secure, reliable mission operations.

• Experience designing, supporting, and troubleshooting high-bandwidth, low-latency multi-site networks, including Cisco routing/switching, Cisco ISE, firewalls, VPNs, optical transport, and high-capacity data circuits (Juniper and Ciena experience strongly valued)
• Strong knowledge of Layer 2/Layer 3, TCP/IP, VLANs, routing, ACLs, DNS, DHCP, high availability, segmentation, MTU, latency, throughput, and traffic optimization
• Linux networking experience, including interfaces, bonding, VLAN tagging, routing, name resolution, port connectivity, CLI troubleshooting, and performance analysis
• Experience with tools such as ip, ss, tcpdump, ping, traceroute, dig, and nslookup
