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 Vehicle Systems Division (VSD) sits at the center of the ideas and data behind current and future systems supplying innovative research and development; technical evaluations during the acquisition process; conceptual and detailed design; assembly, integration, and test; and operational support. Comprised primarily of highly-trained mechanical and aerospace engineers, VSD provides national expertise in the areas of vehicle engineering; guidance, navigation, and controls; robotics; electro-mechanical devices; embedded systems; fluid mechanics; propulsion; thermal control; mechanisms; structures; structural dynamics; and dynamic environments. The Propulsion Department within VSD develops and evaluates cutting-edge propulsion technologies and systems for current and future government and commercial applications. As a Spacecraft Propulsion Engineer (MTS/Senior MTS - Propulsion Engineering) you will perform technical evaluation and assessment of spacecraft propulsion systems for high-priority space missions. Your work will potentially involve propulsion system development, manufacturing, test, and operations for multiple programs. You must have a strong technical foundation and be willing to learn a broad range of new technologies and systems, and effectively communicate results and recommendations to inform critical decisions.
