About the Role

Guidehouse Aerospace Professionals will support ICBM Development, Operations & Sustainment (IDOS) and the entire ICBM enterprise end-to-end across development, operations, and sustainment. The Sentinel program is a once-in-a-generation recapitalization of the U.S. intercontinental ballistic missile (ICBM) enterprise, replacing the Minuteman III weapon system while sustaining Minuteman III readiness throughout the transition to ensure uninterrupted strategic deterrence.

Spanning a multi-state footprint, this effort modernizes launch, support, and security infrastructure; fields a newly designed, technologically advanced missile; and delivers a modern, end-to-end command-and-control architecture, including updated airborne launch capability. Initial fielding is expected to begin in the late 2020s with deployment over approximately nine years, enabling sustained operations through at least 2075.

This role focuses on comprehensive support across acquisition strategy and execution, requirements development, interface integration, cost, schedule, risk, and configuration management, and nuclear surety and cybersecurity compliance. Equally critical, it strengthens Minuteman III sustainment via life-extension planning to maintain safety, reliability, and mission availability during Sentinel fielding. You will work in a dynamic environment, effectively interacting with numerous DOD, military/civilian personnel, and industry partners to drive the mission forward.
