NASA Space Vehicle Modeling and Simulation Engineer
Join CACI International Inc as a Space Vehicle Modeling and Simulation Engineer to support NASA's human‑rated spacecraft systems at the Johnson Space Center in Houston, TX. Candidates should have a passion for spacecraft vehicles and systems, strong software skills, and experience in spacecraft simulation and math model development.
This work involves math model and simulation development, integration, verification and validation on Linux PC platforms using the Trick Simulation Environment and Development Toolkit. The engineer will execute large‑scale simulation verification and validation tasks, develop math models and simulations in support of the Artemis program for NASA space vehicles with a focus on Gateway, and support continual enhancements to the simulation architecture.
Responsibilities
Develop and verify space vehicle system and subsystem simulation math models and validate simulations.
Design and develop math models for spacecraft systems and subsystems, including hardware and software.
Develop simulation scenarios to test nominal and off‑nominal spacecraft operations.
Perform analysis of simulation data to investigate spacecraft system performance.
Present analysis results and their impact on spacecraft performance, vehicle design and mission design to customers.
Qualifications Required
U.S. Citizen or Permanent Resident for access to USG Facilities.
B.S. in Aerospace or Computer Engineering, Computer Science, or related disciplines with experience in software development.
5+ years of experience with aerospace vehicle simulations, math model development, verification and validation.
5+ years of experience with C++ and Python in a Linux environment.
Experience with software version control tools such as Git.
Strong computer and software skills in Linux environments.
Ability to manage multiple priorities with minimal supervision.
Highly responsible, team‑oriented individual with strong work ethic.
Desired
M.S. in Aerospace or Computer Engineering, Computer Science or Modeling and Simulation.
Experience with NASA NPR 7150.2 Class C Certification requirements.
Experience with NASA CACI Trick simulation programming and scenario development.
Experience with NASA’s VERAS Python tool suite.
Experience with spacecraft simulation development using NASA JEOD.
Experience with one or more spacecraft domains including orbital dynamics, robotic dynamics, GN&C, flexible body dynamics, vehicle kinematics, sensors, and effectors.
Experience with Continuous Integration tools and methods.
Experience with Monte Carlo simulation methods.
Experience with MATLAB/Simulink.
Pay Range $76,000 – $155,700 USD.
