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).

Requirements

• Bachelor's or Master's degree in Aerospace Engineering, Physics, or related field
• 5+ years of relevant professional experience preferred
• Proficiency in C, C++, and Python
• Demonstrated experience developing 6-degrees-of-freedom (6-DOF) simulations
• Familiarity with NASA's Trick simulation framework strongly preferred
• Thermal modeling
• Propulsion modeling
• Spacecraft dynamics
• Orbital mechanics
• Power system modeling
• RF communications modeling
• Sensor modeling (IMUs, star trackers, etc.)
• Guidance, Navigation, and Control (GNC) software integration
• 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

Nice To Haves

• 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)
• Experience with Core Flight Software (cFS)
• Custom tool and automation development

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
