Overview

GovCIO is currently hiring for a Senior Network Architect/Engineer to support critical network modernization activities for the U.S. Coast Guard ( USCG ). This technical role focuses on designing, engineering, and executing the transition from legacy transport infrastructure to high-availability, modern enterprise architectures. This position will be remote and requires up to 25% travel.

Responsibilities

The Senior Network Architect/Engineer will serve as the core technical authority for the legacy-to-modern network migration framework. Core responsibilities include:

+ Lead the comprehensive engineering, technical planning, and execution of migrating legacy T1 lines to modern MPLS networks.

+ Analyze and address all routing, bandwidth, quality of service (QoS), and latency implications of shifting from T1 to MPLS .

+ Configure, optimize, and manage enterprise-grade Cisco hardware, specifically Catalyst 8300 edge platforms and Catalyst 9200L switches.

+ Architect and implement robust, high-availability networks utilizing Hot Standby Router Protocol ( HSRP ).

+ Design and deploy strict dual-homed HSRP redundancy frameworks across all four (4) primary network hubs to eliminate failure points.

+ Develop the foundational architecture required for eventual, seamless integration into CGOne for central network monitoring.

+ Conduct technical root cause analysis and performance tuning on Cisco hardware during circuit cutover phases.

+ Proactively identify architectural risks during the T1 decommissioning process and design targeted engineering workarounds.

+ Develop and maintain comprehensive technical documentation, low-level designs (LLDs), and network topology diagrams for all four hubs.
