Multi-Domain Trajectory Design Engineer

The Enterprise Effects Division (EED) drives integration of Aerospace’s strategic capabilities across the national space enterprise. The divisionleveragesa broad array of engineering disciplines against a 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-atmosphericflight design formissiles,hyperglidevehicles, and reentry vehicles. Relevant skills include orbital mechanics, astrodynamics, trajectory design and optimization, and atmospheric flight modeling and simulation.We are seekinga Member of the Technical Staff/Senior Member of the Technical Staffto join the EMFDD team.The selected candidate will provideexpertisefor a wide range of customer flightmechanicsneeds, supporting analysis, research, and development requests. The work will require candidates to provide deep technical solutions while also collaborating with engineering partners tofacilitateintegrated solutions for our customers’ hardest problems. Customers will include defense, intelligence, and civil and commercial organizations.
