Senior Network/Communications Engineer

Nakupuna Consulting is seeking a Senior Network/Communications Engineer to provide senior-level engineering leadership for enterprise wireless, voice, and data modernization initiatives in support of the Marine Corps Enterprise Network (MCEN-N) Wireless Lifecycle Refresh and Expansion program. This position will lead the design, configuration, integration, and troubleshooting of advanced Cisco Systems routing, switching, wireless, and Unified Communications environments, delivering secure, resilient, and mission-ready converged voice, video, and data capabilities across six U.S. Marine Corps installations under the PEO Digital TCS Program Office.

The Senior Engineer will serve as a technical leader responsible for verification site surveys, engineering design, and EFIST (Engineer, Furnish, Install, Secure, and Test) execution of wireless access points, wireless controllers, IP-based voice services, routing and switching infrastructure, and supporting enterprise network components. This effort includes both replacement of end-of-life hardware and expansion of WLAN capabilities in accordance with Zero Trust and Comply-to-Connect principles.

This role also provides senior engineering expertise for enterprise Cisco Systems Unified Communications and IP telephony environments, including call processing architecture, dial plan development, voice gateway integration, SIP/SRST survivability, QoS implementation, and voice quality troubleshooting. The Senior Engineer will ensure seamless integration of voice, wireless, and data services with existing MCEN-N enterprise services to maintain operational continuity and mission effectiveness.

The candidate will work closely with Lead Systems Engineers, field implementation teams, and government stakeholders to support Technical Readiness Reviews (TRR), Government Acceptance Testing (GAT), cutover planning, and final operational turnover. The ideal candidate is willing and able to travel between North Carolina, South Carolina, Georgia, and Florida, bringing innovation, technical discipline, and mission focus to every solution deployed.
