SAIC is seeking a CAD Modeling and Simulation Engineer in Chantilly, VA to support a government customer. The successful candidate will:

·         Develop and maintain physics-based simulation models of spacecraft systems, including structures, sensors, and mission environments.

·         Perform end-to-end performance modeling for satellite missions, integrating sensor, orbital, and environmental models.

·         Create and modify CAD-based satellite geometries, including material property assignments for use in thermal, structural, and radar/optical signature analyses.

·         Conduct sensor phenomenology studies, including optical, infrared, or radar modeling for detection, tracking, and signature analysis.

·         Perform orbital mechanics modeling including orbit determination, orbital maneuvering, and spacecraft flight dynamics

·         Use scripting languages (Python, MATLAB, or similar) to automate workflows, perform data analysis, and interface between simulation tools.

·         Collaborate with multidisciplinary teams (systems engineering, GNC, payload, mission design) to ensure model fidelity and consistency.

·         Generate technical documentation, simulation reports, and visualizations to communicate findings and support design decisions.

·         Support trade studies and design reviews by providing modeling insights into performance impacts of design changes.

Qualifications

·         Bachelor's or Masters degree in Aerospace Engineering, Mechanical Engineering, Physics, or a related field with 5+ years of professional technical experience

·         3+ years of experience in modeling and simulation for aerospace or space systems.

·         Active Top Secret/SCI w/Poly Clearance

·         Proficiency with CAD tools (e.g., SolidWorks, Creo, CATIA, NX, or similar) including geometry creation and material property definition.

·         Strong understanding of sensor phenomenology --such as optical, infrared, or radar systems --and associated modeling methods.

·         Intermediate Python programming experience, demonstrated through hands-on experience with tasks such as data manipulation, automation, and development of Python-based solutions. Experience with libraries such as NumPy, SciPy, pandas, and matplotlib is beneficial.

·         Ability to communicate technical results clearly in written and verbal formats.
