The Network Engineer, Senior designs, implements, and optimizes complex

enterprise network infrastructures that support mission-critical systems in

highly regulated government environments. This role goes beyond traditional

network engineering and requires a well-rounded infrastructure expert who can

troubleshoot and resolve complex connectivity issues across network, server, and

application layers. Hands-on problem solver who thrives in high-availability

environments and deployment of LAN, WAN, and wireless solutions to ensure

resilient, scalable, and secure connectivity across data centers, cloud

environments, and remote sites. Oversees advanced troubleshooting and

performance tuning for multi-vendor network hardware and software, resolving

issues escalated beyond lower tiers of support. The engineer partners with

security, systems, and application teams to align network design with zero-trust

principles, monitoring strategies, and compliance requirements. This position

also provides technical leadership on network roadmaps, technology selection,

and major upgrade or migration initiatives.
