NASA Space Vehicle Modeling and Simulation Engineer

CACI • Houston, TX

13h • Onsite

About The Position

CACI is seeking an experienced Space Vehicle Modeling and Simulation Engineer to collaborate with NASA's human-rated spacecraft systems in support of national space exploration initiatives at NASA / Johnson Space Center in Houston, TX. This role involves developing, integrating, verifying, and validating math models and simulations on Linux PC platforms using the Trick© Simulation Environment and Development Toolkit. The engineer will execute large-scale simulation verification and validation tasks, and develop math models and simulations for the Artemis program, focusing on lunar bases and lunar surface exploration for NASA space vehicles. The ideal candidate will have spacecraft domain experience, particularly in Guidance, Navigation, and Controls, along with a strong simulation development background. This position requires a self-motivated individual with excellent verbal and written communication skills, strong customer relationship skills, a positive team-player attitude, and flexibility to take on new assignments. The candidate should be able to articulate complex technical ideas effectively and share a passion for space exploration and the development of human-rated space vehicles.
