Multi-Domain Trajectory Design Engineer/Senior Multi-Domain Trajectory Design Engineer

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. We are seeking an Engineering Specialist/Senior Engineering Specialist to join the EMFDD team. 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.

• Reentry risk and range safety assessments 

• Astrodynamics analysis: orbit propagation, maneuver design/optimization for orbit transfer, station keeping, graveyard, disposal, and reentry 

• Operational support for nominal launch, spacecraft deployment/transfer, anomaly resolution, and emerging events  

• Maneuver and orbit design/optimization for Rendezvous and Proximity Operations (RPO) with complex constraints 

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

What You Need to be Successful 

Minimum Requirements for Engineering Specialist – Flight Mechanics: 

• Bachelor’s degree from an accredited program in Engineering, Science, Mathematics, or related technical discipline. 

• Typically eight or more years of experience of relevant technical work 

• Experience in one or more of the following subjects: space mission analysis and design, advanced astrodynamics, algorithm design, software development, or mathematical modeling, multi-objective optimization, trajectory simulation and performance optimization of spacecraft, missiles, and reentry vehicles 

• Proficiency with one or more of the following programming languages/tools: C, C++, Python, Fortran, MATLAB. 

• Ability to support multiple programs and/or activities simultaneously and to serve as a technical point-of-contact. 

• Demonstrated technical team leadership and mentorship skills. 

• Effective written and verbal communication skills. 

• Willing to travel domestically to customer and contractor facilities (approx. 10%) 

• This position requires the ability to obtain and maintain a security clearance, which is issued by the US government. U.S citizenship is required to obtain a security clearance. 

In addition to the above, the minimum requirements for the Senior Engineering Specialist – Flight Mechanics position include:  

• Twelve or more years of experience of relevant technical work  

• The ability to lead and execute large and sustained technical efforts with vision to propose, scope, and coordinate these efforts across organizational boundaries   

How You Can Stand Out  

It would be impressive if you have one or more of these:
