What does a numerical simulation software engineer do?

A Numerical Simulation Software Engineer develops and maintains software tools that use advanced mathematical models to simulate physical, chemical, or engineering processes. They work closely with scientists and engineers to create algorithms that solve complex numerical problems, such as fluid dynamics, structural analysis, or thermal simulations. Their role often involves programming, optimizing code for performance, and validating simulation results to ensure accuracy. These engineers help organizations predict real-world behavior and make better decisions based on virtual experiments.

What are the key skills and qualifications needed to thrive as a numerical simulation software engineer?

To thrive as a Numerical Simulation Software Engineer, you need a strong background in mathematics, physics, and computer science, usually supported by a relevant engineering or science degree. Proficiency in simulation tools (such as ANSYS, COMSOL, or Abaqus), programming languages (like Python, C++, or MATLAB), and experience with high-performance computing environments is essential. Analytical thinking, attention to detail, and effective communication are vital soft skills for interpreting results and collaborating with multidisciplinary teams. These capabilities ensure accurate modeling, efficient problem-solving, and successful project outcomes in complex engineering environments.

What are some common challenges numerical simulation software engineers face when developing simulation tools?

Numerical Simulation Software Engineers often encounter challenges such as ensuring the accuracy and stability of complex algorithms, optimizing code for computational efficiency, and maintaining compatibility across diverse hardware and software platforms. Balancing the need for detailed, realistic simulations with performance constraints is a frequent hurdle. Additionally, clear communication with domain experts and other engineering teams is essential to translate theoretical models into practical, reliable software solutions.

What is the difference between Numerical Simulation Software Engineer vs Computational Scientist?

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 role:


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
  • 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
