Freelance Simulation Software Engineer Jobs in Texas

Simulation and Modeling Software Developer

Houston Texas

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.

About the Position:

We are seeking a talented and experienced Simulation and Modeling Software Developer to join our Software Simulation team. The Simulation and Modeling Developer will play a key role in developing models and building simulations that support design, analysis, and testing of flight software, GNC, and ground software as well as training for flight operations. 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 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 flight 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

• Spacecraft dynamics
• Orbital mechanics
• Power system modeling
• RF communications modeling
• Sensor modeling (IMUs, star trackers, etc.)
• Guidance, Navigation, and Control (GNC) software integration

• Development Tools & Processes

• Experience with Agile software development methodologies

• Proficiency with Git version control and GitLab
• Familiarity with Atlassian tools (Jira, Confluence, etc.)
• Experience with Docker containerization and Linux environments

• Preferred Additional Skills

• Thermal analysis and modeling
• 3D modeling tools (especially Blender) and visualization software
• 3D spatial reasoning and geometric algorithms
• Computer graphics algorithms
• Monte Carlo simulation techniques
• NASA's General-Use Nodal Network Solver (GUNNS)
