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 multiple NASA lunar missions in development and additional private missions on our manifest, we pride ourselves in supporting NASA, 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.

About the Position:

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).

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
• 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

Requirements:

• BS or MS in Aerospace Engineering, Physics, or related field with 5+ years of experience preferred
• C, C++, and Python programming 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
