About Intuitive Machines 

Intuitive Machines is an innovative and cutting-edge space company making cislunar space accessible to both public and private customers. Our mission is to further science and exploration, communications, and economic progress from the Earth to the Moon and beyond. With the first commercial lunar landing in history, multiple NASA lunar missions in development, and additional private missions on our manifest, we pride ourselves in supporting our customers and the nation in paving the way to return humans to the surface of the Moon. Our world-class team includes experts in all aspects of spacecraft subsystems design, development, and test, on-orbit operations, and safety.   

*Employment in this role is contingent upon NASA selecting Intuitive Machines as the winner of the LTVS program, scheduled for announcement later in 2025. 

Responsibilities:

• Design, implement, test, and “own” environmental, vehicle and I/O simulation models
• Collaborate with vehicle software, GNC, and other subsystem engineers and subject matter experts in creating high-fidelity environment, sensor, effector, and interface models
• Create and execute simulation model verification tests
• Faster-than-real-time and real-time spacecraft simulation development and maintenance
• Hardware-in-the-loop (HWIL) simulation development and testing
• Human-in-the-loop simulation development
• Support Fault, Detection, Isolation, and Recovery (FDIR) testing through fault modeling
• Write model unit tests and coordinate high-level testing of implemented models
• Develop and maintain Software Quality Assurance (SQA) tools
• Provide simulation support to flight software, ground software, and operations teams

The ideal candidate for the role of Simulation and Modeling Software Developer will be encouraged to take initiative in developing, maintaining, and improving simulation models, tools, and infrastructure. The position is multidisciplinary in nature as the simulation supports a number of internal and external customers which requires regular collaboration with other subsystem engineers for model development and technical support for simulation environments (HWIL simulations, FDIR testing, operations training, etc). 

Requirements: (This role is posted at multiple levels, with multiple openings spanning entry level to technical lead)

• BS or MS in Aerospace Engineering, Physics, or related field with 5+ years of experience preferred
• C, C++, and Python programming experience
• 6-degrees-of-freedom simulation development experience
• Experience in one or more areas including spacecraft dynamics, thermal modeling, power modeling, RF comm modeling, sensor modeling (IMUs, star trackers, LIDAR, etc), GNC software integration
• Experience with Agile software development tools and processes
• Experience with Atlassian tools, Git version control, Gitlab, Docker, and Linux is preferred
• Experience with the following is a plus:
  • High Level Architecture (HLA)
  • Core Flight Software
