Network Architect, Senior

Peraton•Herndon, VA

About The Position

We are seeking a highly skilled and innovative Network Architect to join our team in the greater DMV area, supporting the Army National Guard. Responsibilities Lead enterprise network architecture across classified and unclassified environments; design resilient, secure, and scalable DoDIN services for NGB, ARNG, State JFHQs, and USAR support. Develop end‑to-end architectures for WAN, ICAN, data center, virtualized hosting, VoIP topologies, Army 365 services, and cloud on‑ramps (cARMY‑Azure) across DEV/TEST/Stage/Production/COOP. Produce technical architecture plans, DoDAF‑aligned connectivity diagrams, site‑specific bills of materials, ROMs/COAs, and cost estimates to support implementation, modernization, and expansion. Define standards, design patterns, and configurations for routing, switching, firewalls, VPN, DNS, web proxy, identity services, and multi‑environment integrations to meet DoD/Army/ARNG technical requirements. Ensure designs satisfy STIG/IAVM compliance, RMF/ATO objectives, COOP/DR requirements, and CCRI readiness criteria; incorporate security and operational constraints into architecture decisions. Evaluate emerging technologies and devices; recommend upgrades to address capacity, performance, interoperability, and cybersecurity needs. Collaborate with RCC‑ARNG, NETCOM, ARCYBER, SOC, CIRT, EA, and managed‑service stakeholders to align architectures with operational realities and sustainment models. Guide change and release management from an architectural perspective: produce transition diagrams, deployment runbooks, engineering artifacts, and lifecycle sustainment plans. Provide decision‑grade briefings and governance support for architecture review boards and portfolio modernization planning. #ENOCS
