Description

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 Master's 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.
