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 avariedand 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 corecomponentof EED, the Earth Orbit Flight Dynamics Department (EOFDD) providesflight mechanicsexpertisefor launch vehiclesand space vehicles.Relevant skillsinclude orbital mechanics, astrodynamics, trajectory design and optimization, and atmospheric flight modeling and simulation.We are looking for anEngineering Specialist/Senior Engineering Specialistto join the EOFDD team.The selected candidate willprovideexpertisefora wide rangeofcustomerflight mechanics needs,supporting bothanalysis and research and developmentrequests.Thework will require candidates to provide deep technical solutionswhile alsocollaboratingwith engineering partnerstofacilitateintegrated solutions for our customers’hardest problems.Customers will includedefense, intelligence, and civil and commercialorganizations. 

Work Model
