The Aerospace Corporation is the trusted partner to the nation's space programs, solving the hardest problems and providing unmatched technical expertise. As the operator of a federally funded research and development center (FFRDC), we are broadly engaged across all aspects of space- delivering innovative solutions that span satellite, launch, ground, and cyber systems for defense, civil and commercial customers. When you join our team, you'll be part of a special collection of problem solvers, thought leaders, and innovators. Join us and take your place in space. The Defense Systems Group (DSG) provides analysis-based decision support to senior leaders on space architectures, policy and strategy, developmental planning, system of systems engineering, and threat reduction to help shape future space missions across the national security space enterprise. DSG is unique at Aerospace as it not only directly supports major customers, including Air Force Space Command, U.S. Strategic Command, Air Force Materiel Command, and senior leadership at the Pentagon, but also provides a broad range of services and support across the national space enterprise, maintaining vertical responsibilities with customers but also horizontal, matrixed responsibilities across the corporation. Aerospace's GPS Program Office is a high-performing team bringing technical engineering capabilities to the fast-moving and highly impactful field of space-based navigation. The team participates in a wide range of technical activities, including leading special studies to shape the future of the nation's military and civilian GPS system, working with government, contractors, and military and civil GPS users to influence customer decisions on GPS satellites and military user equipment. We are looking for an enthusiastic GPS Satellite Subsystem Engineer (Project Engineer/Sr. Project Engineer - Systems Engineering - Acquisition) with excellent communication, leadership, and interpersonal skills to provide technical and programmatic support to the GPS III/IIIF development, production and integration efforts, as well as to help define the next generation of PNT space systems. The successful applicant will be required to interact with the USSF, Aerospace's Engineering & Technology Group (ETG), and contractors in a fast-paced program office environment. The selected applicant will be expected to proactively assist with leading Aerospace's efforts to help its USSF customer and contractor team integrate satellite subsystems and those subsystems' components into the satellite. This is an excellent opportunity that will provide visibility for career growth through interaction with Aerospace senior management and experience in a program office environment. You will build and maintain close working relationships with government and contractor counterparts as well as staff and management across Aerospace.
