NASA Space Suit Modeling and Simulation Engineer

About the role

CACI is hiring a Space Suit Modeling and Simulation Engineer to work with NASA's human-rated space suit and spacecraft systems at NASA Johnson Space Center in Houston, Texas. The work supports the Artemis program and the AxEMU (Axiom Extravehicular Mobility Unit) math model and simulation development. The engineer develops math models and simulations on Linux PC platforms using the Trick simulation environment, identifies improvements to models and scenarios, analyzes simulation data and helps enhance the simulation architecture. The position requires a minimum NAC clearance and up to 10% travel within the continental US.

Key responsibilities

• Develop AxEMU system and subsystem simulation math models, verify model requirements and validate the simulation and models.
• Design and develop math models for AxEMU systems and subsystems, including hardware and software.
• Develop simulation scenarios to test nominal and off-nominal space suit operations.
• Develop interface code to integrate space suit flight software into the simulation environment.
• Analyze simulation data to investigate space suit system performance.
• Present analysis results and their impact on space suit performance and design to customers.

Required profile

• U.S. citizen or permanent resident to access U.S. government facilities.
• B.S. in Mechanical, Electrical, Aerospace, Biomedical Engineering or a related discipline, with 3+ years of experience in software development, including project design, programming, testing, verification, validation and documentation.
• Experience with aerospace vehicle or space suit simulations and math model development.
• Experience with Trick simulations and math model verification and validation.
• Experience with C++ and Python in a Linux environment, and with version control tools such as Git.
• Strong computer and software skills in Linux, ability to manage multiple priorities with minimal supervision, and strong communication skills.

Required skills

• Trick simulation environment and development toolkit
• C++ and Python in Linux
• Git
• Desired: GUNNS tool suite, Continuous Integration tools, space suit subsystem design experience

What we offer

• Proposed pay range of $76,000 - $155,700 USD, depending on experience, skills and contract terms.
• Healthcare, wellness, financial, retirement, family support, continuing education and time off benefits.
• A culture of integrity, a flexible time off benefit and learning resources.
