This opportunity resides with Global Security (GS). Mission Technologies’ Global Security (GS) group comprises live, virtual, constructive (LVC) solutions; fleet sustainment; nuclear and environmental; and Australia business.

As a trusted partner to our military customers, HII designs, develops and operates the largest LVC enterprise that prepares warfighters for cross-domain battle. With advanced technologies to enable mission readiness, HII understands that preparation requires full coordination—not readiness in piece-parts.

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.

HII supports 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. HII meets clients’ toughest nuclear and environmental challenges.

HII Mission Technologies is seeking an Information System Security Officer (ISSO) to support the Joint Integrated Test and Training Center – Nellis (JITTC‑N) at Nellis AFB. In this role, you will provide cybersecurity oversight, RMF documentation, system security engineering support, and continuous monitoring for advanced modeling and simulation (M&S) systems—including environments such as the Joint Simulation Environment (JSE), Virtual Air Training System (VATS), and other high‑end virtual training architectures supporting USAFWC/ACC mission sets.

You will work as part of an onsite team delivering Advanced Tactics, Training, and Test capabilities across a broad range of simulator and distributed training activities. The ideal candidate brings strong interpersonal skills, deep knowledge of RMF and DoD cybersecurity requirements, and the ability to design, document, and secure complex networked systems.

Your work directly enables the secure operation of cutting‑edge simulation environments used to train, test, and prepare warfighters for complex operational missions. By ensuring compliance, mitigating risk, and maintaining a strong cybersecurity posture, you help protect critical systems that shape the future of Air Force tactics and readiness.

• Draft, review, and update RMF artifacts required to obtain and maintain ATO for emerging systems, including advanced M&S environments such as JSE and VATS.
• Support cybersecurity compliance and continuous monitoring for virtual training systems, distributed simulation environments, and related mission systems.
• Evaluate and document security controls for systems supporting high‑fidelity simulation, virtual air training, and distributed mission operations.
• Assist in securing network architectures and system configurations used in environments such as VATS, JSE, and other USAFWC/ACC training systems.
• Maintain configuration records for workstations, servers, routers, firewalls, switches, and simulation‑related infrastructure.
• Provide cybersecurity guidance to engineering and M&S teams developing…
