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.

Job Summary 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 Member of the Technical Staff to provide expertise for a wide range of customer flight dynamics 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
* The selected candidate will be required to work full time, on-site in El Segundo, CA, Colorado Springs, CO, Chantilly, VA, or Albuquerque, NM. What You'll Be Doing
* 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, stationkeeping, graveyard, disposal, and reentry events

* Analysis of vehicles with chemical and/or electric propulsion

* Evaluating contested missions applications for space systems to understand threat performance, assess vulnerabilities, and improve system resiliency

* 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 to service customer requests as stand-alone services and/or ready-to-integrate submodules
* Combining AI/ML/RL techniques with flight mechanics modeling for assessing complex analysis and decision-making trade spaces

* Performing research and development and building new flight dynamics tools to cultivate and maintain a healthy and modern internal tool base

* Leveraging external tools like ASSET, GPOPS-II, SNOPT, POST, OTIS, Copernicus, GMAT, EMTG, etc. where appropriate to augment internally developed capabilities Additional inter-department collaboration opportunities:
* Cislunar and exploration-class orbital mechanics analysis and trajectory optimization

* Hypersonics, missiles, interceptors, and reentry vehicle trajectory design and optimization (including Golden Dome support)

* Time-dependent Traveling Salesman Problems and Facility Location Problem analysis (multi-destination, multi-vehicle trajectory frameworks)

* Integrated, multi-disciplinary RPO system simulations What You Need to be Successful

Minimum Requirements for the Member of the Technical Staff - Flight Mechanics position:
* Master's degree from an accredited college or university in aeronautical/astronautical engineering, physics or applied mathematics, or related disciplines

* 0-1 years of experience in flight mechanics, astrodynamics, maneuver optimization, trajectory optimization, launch vehicle trajectory design, hypersonic vehicle modeling, or general trajectory modeling and simulation

* Proficiency in one or more of the following programming languages and environments: C, C++, Fortran, Python, Java script, Linux, and/or MATLAB

* 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. This position will require a TS clearance (SSBI) with SCI access…
