2026 Emerging Missions Flight Dynamics Engineer

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. Job Description The Enterprise Effects Division (EED) drives integration of Aerospace's strategic capabilities across the national space enterprise. The division leverages a broad array of engineering disciplines against a diverse and dynamic portfolio of programs, customers, and national challenges. EED spans the capability lifecycle from concept and architecture design to performance assessment to application of space and space-enabled capabilities. As a core component of EED, the Emerging Missions Flight Dynamics Department (EMFDD) provides flight mechanics expertise for the cislunar domain, multi-objective "traveling salesman" trajectory sequence generation, facility location optimization, and trans-atmospheric flight design for missiles, hyperglide vehicles, and reentry vehicles. Relevant skills include orbital mechanics, astrodynamics, trajectory design and optimization, and atmospheric flight modeling and simulation. The selected candidate will provide expertise for a wide range of customer flight mechanics needs, supporting analysis, research, and development requests. The work will require candidates to provide deep technical solutions while also collaborating with engineering partners to facilitate integrated solutions for our customers' hardest problems. Customers will include defense, intelligence, and civil and commercial organizations.
