This individual serves as a Subject Matter Expert on routing for the enterprise WAN - assisting the Network Architect with Border Gateway Protocol (BGP) design, peering, and policy across NIPRNet, SIPRNet, and DISN service delivery points - and is accountable for the availability, performance, and STIG compliance of circuits supporting operational mission traffic worldwide. Roles and Responsibilities: * Design, implement, and maintain BGP routing architecture across the enterprise WAN, including peering relationships, autonomous system boundaries, and route policy enforcement. * Serve as the escalation authority for complex WAN faults - route flapping, asymmetric paths, MTU and fragmentation issues, black-holed prefixes, and provider circuit degradation. * Engineer and 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. * Configure and sustain QoS, traffic engineering, and path selection to prioritize command and control, VTC, and VoIP traffic across constrained transport. * 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 outage restoration. * Monitor WAN health and capacity using SolarWinds, NetFlow, and SNMP-based tooling; produce trend analysis and capacity recommendations for government leadership. * Manage Type 1 encryptor configuration and key management coordination in support of secure enclave connectivity. * Mentor junior network administrators, review proposed configuration changes, and represent WAN engineering positions at CCB and technical review boards. ## Related Videos - [IP Authentication: A Tale of Performance Pitfalls and Challenges in Prod](https://www.wearedevelopers.com/videos/1413-ip-authentication-a-tale-of-performance-pitfalls-and-challenges-in-prod) - [Getting under the skin: The Social Engineering techniques](https://www.wearedevelopers.com/videos/38-getting-under-the-skin-the-social-engineering-techniques) - [IoT: The road to sustainability](https://www.wearedevelopers.com/videos/557-iot-the-road-to-sustainability) - [Remote Driving on Plant Grounds with State-of-the-Art Cloud Technologies](https://www.wearedevelopers.com/videos/251-remote-driving-on-plant-grounds-with-state-of-the-art-cloud-technologies) - [Demystifying application networking in the cloud](https://www.wearedevelopers.com/videos/675-demystifying-application-networking-in-the-cloud) - [How Cisco embraced a DevOps culture within its network engineering team](https://www.wearedevelopers.com/videos/99-how-cisco-embraced-a-devops-culture-within-its-network-engineering-team) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated) - [Best US AI Conferences for CTOs in 2026: Build vs. Buy, Vendor Evaluation, and Peer Intelligence](https://www.wearedevelopers.com/magazine/736-best-us-ai-conferences-for-ctos-in-2026-build-vs-buy-vendor-evaluation-and-peer-intelligence) - [What Are The Top Skills Required For Azure Developers?](https://www.wearedevelopers.com/magazine/77-what-are-the-top-skills-required-for-azure-developers)
