Sr. Network Administrator

About the Team

This opportunity resides with Global Security (GS) within HII's Mission Technologies division. Our team of more than 7,000 professionals worldwide delivers all-domain expertise and advanced technologies in service of mission partners across the globe. As a trusted partner to our military customers, HII designs, develops, and operates the largest Live, Virtual, and Constructive (LVC) enterprise that prepares warfighters for cross-domain battle.

For more than 40 years, the U.S. Navy has entrusted HII to maintain and modernize the vast majority of its fleet. With a holistic approach to life-cycle maritime defense systems—from small watercraft to submarines, surface combatants, and aircraft carriers—HII ensures a high state of readiness. We also support the Department of Energy's national security mission through the management and operation of its sites, as well as the safe cleanup of legacy waste across the country.

About the Role

The Navy Integrated Training Environment (NITE) Network Administrator serves as a critical component of the Network Operations and Security Center (NOSC), functioning as the helpdesk for network operations support. You will partner with Navy, DISA, and commercial circuit providers to ensure continuous connectivity for customers and sites across multiple classification levels.

In this role, you will be the first line of defense for network stability, diagnosing and resolving WAN circuit issues, equipment failures, and cryptographic device configurations. Your day-to-day involves coordinating the installation and reconfiguration of network hardware and software, maintaining Information Assurance compliance, and supporting remote sites in restoring network services. You will work within a supportive environment where preparation requires full coordination, ensuring that mission readiness is achieved through integrated systems rather than piece-parts.
