• Demonstrated experience with orbital mechanics and at least one of the following: orbit maneuver design, Rendezvous and Proximity Operations (RPO), maneuver detection, conjunction assessment, or space domain awareness analysis.
• Proficiency in Python or C++, or the demonstrated ability to rapidly apply existing programming skills in another language to Python or C++ for modeling, simulation, and data analysis.
• Proven ability to collaborate effectively in a multi-disciplinary, mutually supportive engineering environment.
• Experience conducting technical analyses and refining results in response to internal and external peer reviews.
• Ability to work on-site in Chantilly, VA.

Clearance Requirements:

• Active TS/SCI clearance with the ability to obtain and maintain a polygraph.

Preferred Qualifications:

• Advanced degree (MS) in Aerospace Engineering, Astrodynamics, or a related discipline.
• Experience with RPO mission design, autonomous proximity operations, or satellite servicing concepts.
• Experience with maneuver detection, covariance analysis, and conjunction assessment in operational or high-fidelity simulation environments.
• Familiarity with High Performance Computing environments and/or GPU-accelerated computation for large-scale simulations.
• Experience with tools such as STK, FreeFlyer, GMAT, Orekit, or similar astrodynamics and mission analysis software.
• Prior experience supporting national security space or intelligence community space programs.

Physical Requirements:

• Work is typically performed in an office or SCIF environment.
