Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
The role involves performing trajectory design and optimization for launch vehicles and spacecraft while developing space warfighting tactics and operational concepts. You will provide deep technical solutions for complex flight mechanics problems and collaborate with partners to support defense, intelligence, and commercial customers.
Candidates must hold a bachelor's degree in a relevant engineering or science field and possess at least five years of experience in flight mechanics or astrodynamics. Proficiency in programming languages such as C++, Python, or MATLAB is required, along with the ability to obtain a U.S. security clearance.
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.
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 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 Earth Orbit Flight Dynamics Department (EOFDD) provides flight mechanics expertise for launch vehicles and space vehicles. Relevant skills include orbital mechanics, astrodynamics, trajectory design and optimization, and atmospheric flight modeling and simulation. We are looking for a Senior Member of the Technical Staff or Engineering Specialist to join the EOFDD team. The selected candidate will provide expertise for 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 to facilitate integrated solutions for our customers’ hardest problems. Customers will include defense, intelligence, and civil and commercial organizations.
Work Model
This position will be a hybrid work model based in El Segundo, CA, Chantilly, VA, or Albuquerque, NM, with the expectation that the selected candidate works at least 4 days a week onsite, as the business needs allow.
What You’ll Be Doing
Primary Support
Trajectory design and optimization for launch vehicles and spacecraft for missions operating in 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, station keeping, graveyard, disposal, and reentry events
Evaluating contested missions applications for space systems to understand threat performance, assess vulnerabilities, and improve system resiliency
Develop space warfighting tactics aligned to the Chief of Space Operations (CSO) and Commander of US SPACECOM priorities by providing technical, operational, and risk assessments
Maneuver and orbit design, selection, and optimization for missions that support Rendezvous and Proximity Operations (RPO) objectives with complex operational constraints
Developing Concepts of Operations (CONOPS), exploring Tactics, Techniques, and Procedures (TTPs), and incorporating operational constraints into the design and maturation of space systems
Providing operational support for nominal launch and spacecraft deployment and transfer sequences, anomaly resolution, and on-call emerging events
Utilizing optimal control, flight mechanics, and computer science/algorithm development skills to create new capabilities and modernize existing capabilities to service customer requests as stand-alone services and/or ready-to-integrate submodules
Leveraging external tools like ASSET, GPOPS-II, SNOPT, POST, OTIS, Copernicus, GMAT, EMTG, etc. where appropriate to augment internally developed capabilities
Communicating effectively with customers and management through timely reporting of technical issues, analysis reports, and recommendations
Additional inter-department partnership collaborations opportunities:
Cislunar and exploration-class orbital mechanics analysis and trajectory optimization
Hypersonics, missiles, interceptors, and reentry vehicle trajectory design and optimization
Time-dependent Traveling Salesman Problems and Facility Location Problem analysis
Integrated, multi-disciplinary RPO system simulations
What You Need to be Successful
Minimum Requirements for the Senior Member of the Technical Staff – Flight Mechanics position:
Bachelor’s degree in aeronautical/astronautical engineering, physics or applied mathematics, or related disciplines
Five or more years of experience in flight mechanics, astrodynamics, maneuver optimization, trajectory optimization, launch vehicle trajectory design, hypersonic vehicle modeling, or general trajectory modeling and simulation
Experience in space-relevant TTPs development, operational planning, or battle management
Proficiency in one or more of the following programming languages and environments: C, C++, Fortran, Python, Linux, Java, and/or MATLAB
The ability to operate independently, often in the presence of ambiguity, and still deliver high-quality, innovative, and specialized end products to a range of customers
Willing to travel domestically approx. 10%
The ability to obtain and maintain a US security clearance is required. U.S citizenship is required to obtain a security clearance.
In addition to the above, the minimum requirements for the Engineering Specialist – Flight Mechanics position include:
Eight or more years of experience of relevant technical work or PhD
Demonstrated technical excellence in the relevant job capabilities and functions
The ability to operate independently, often in the presence of ambiguity, and still deliver high quality, relevant end products to a range of customers
The ability to build and perform on multi-disciplinary teams to deliver integrated analysis products
How You Can Stand Out
It would be impressive if you have one or more of these:
Advanced degree in aeronautical/astronautical engineering, physics or applied mathematics, or related disciplines is strongly desired
Graduate level course work, research and/or experience in one or more of the following areas: orbital mechanics, astrodynamics, ascent trajectory modeling, hypersonic flight simulation, optimal control, flight mechanics, and/or trajectory modeling and simulation
Experience using or building analysis software to combine numerical methods, orbital or flight mechanics, and optimization approaches for launch vehicles, missiles, interceptors, spacecraft, or reentry vehicles (hypersonics)
Familiarity with National Security Space Enterprise operational communities and experience with translating warfighter needs into analysis frameworks.
Experience with nonlinear programming (non-linear programming), direct methods, gradient-based optimization, parameter optimization, genetic algorithms, evolutionary algorithms, heuristic optimization methods, indirect methods, and/or calculus of variations
Advanced algorithm development skills to include parallel processing and scripting experience
Experience with contested space trajectory applications, military exercises, and wargaming events
Current TS/SCI and/or TS/SAP Access
