• Ability to configure and troubleshoot eBGP and iBGP, including route reflectors, confederations, and full-mesh peering designs.
• Experience tuning BGP routing policy with route maps, prefix lists, AS-path filters, communities, local preference, MED, and AS-path prepending; establishing and sustaining peering with DISA/DISN service delivery nodes and commercial transport providers; and working with BGP convergence tuning, dampening, BFD, and route leak/hijack mitigation.
• Proficiency with OSPF, EIGRP, MPLS L2/L3 VPNs, VRFs, QoS policy for voice and mission traffic, and IPv4/IPv6 dual-stack operations.
• Hands-on administration of Cisco IOS-XE, IOS-XR, and NX-OS and Juniper Junos routing platforms in an operational production network.
• Experience with Type 1 inline network encryptors, such as TACLANE/KG-175 and HAIPE, and DISA circuit lifecycle actions, including TSR/TSO and DISA Direct/SNAP.
• Working knowledge of DISA STIGs, RMF, IAVA remediation, and change control under DoD configuration management processes.
• Packet-level troubleshooting skills using Wireshark/tcpdump, SPAN/TAP captures, and NetFlow to isolate faults across provider and government segments.
• Willingness to work evening and rotational shifts, including weekends and holidays.
• Occasional CONUS/OCONUS travel may be required.

Nice To Haves

• Active CCNP Enterprise, JNCIP-SP, or equivalent routing certification (identified as preferred in the qualifications).
• CCIE Enterprise Infrastructure or Service Provider, JNCIE-SP, or DoD 8570/8140 IAT Level III certification, such as CASP+ or CISSP.
• Experience with segment routing, MPLS traffic engineering, or EVPN in a large-scale transport core.
• Hands-on experience with Cisco SD-WAN, Juniper SD-WAN, or comparable overlay transport in a DoD/DoW deployment.
• Proficiency with Python and Ansible for configuration deployment, compliance auditing, and network state validation.
• Familiarity with JRSS, DODIN operations, and DoD boundary/CDS architectures.
• Working knowledge of DWDM, SONET/SDH, and carrier Ethernet handoffs supporting long-haul circuits.

Responsibilities

• Maintain BGP routing architecture across the enterprise WAN, including peering relationships, autonomous system boundaries, and route policy enforcement.
• Execute circuit installations, migrations, bandwidth upgrades, and site cutovers with documented rollback plans and minimal mission impact.
• Develop and maintain routing policy standards, IP address and ASN allocation plans, and authoritative network documentation, including logical and physical topology diagrams.
• Apply DISA STIGs to routing and transport devices, remediate IAVA findings, and support RMF assessment and authorization artifacts and POA&M closure.
• Coordinate with DISA, NOC/SOC teams, transport providers, and site network personnel to schedule and validate maintenance actions and restore outages.
• Monitor WAN health and capacity using SolarWinds, NetFlow, and SNMP-based tooling; produce trend analyses and capacity recommendations for government leadership.
• Manage Type 1 encryptor configuration and key-management coordination in support of secure enclave connectivity.
• Troubleshoot enterprise WAN issues from the watch floor and support the availability and performance of circuits carrying operational mission traffic.
