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 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 aMember of the Technical Staff/Senior Member of the Technical Staffto join the EOFDD team.The selected candidate willprovideexpertisefor a wide range of customer flight mechanics needs,supporting both analysis and 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 includedefense, intelligence, and civil and commercialorganizations. 

Work Model

• This position will be a hybrid work model based in El Segundo, CA, Colorado Springs, CO, Chantilly, VA, or Albuquerque, NM, with the expectation that the selected candidatewill workat least4days a week onsite, as the business needs allow.

WhatYou’llBe Doing 

Primary Support

• Trajectory design and optimization for launch vehicles and spacecraft for missionsoperatingin LEO, MEO, HEO, GEO, and other earth-centric regimes

• Astrodynamics and orbital mechanics analysis including orbit propagation and maneuver design and optimization for orbit transfer,stationkeeping, graveyard, disposal, and reentry events
