Simulation Software Engineer (Docking)

Simulation Software Engineer (Docking)

Cimarron is seeking a Simulation Software Engineer to support docking systems for the Orion program with NASA in either Houston, TX or Denver, CO. The Orion Multi-Purpose Crew Vehicle is NASA's next-generation spacecraft built to carry astronauts beyond low-Earth orbit — back to the Moon and eventually to Mars. As part of the Artemis program, this role puts you at the center of human spaceflight, developing the simulation and ground software systems that prepare crews for deep space missions. If you are driven by a passion for space exploration and want your work to directly support the future of human spaceflight, apply today!

Key Duties:

• Perform Docking Ground Software Systems Engineering for simulation systems supporting Orion MPCV Artemis 3 Spacecraft, including development of ground capabilities, software design, software production, and software test.
• Perform simulation software (OrionSim) development and unit/functional testing for Orion Docking systems using Agile methodologies.
• Perform SOCRRATES (SOC) Ground Software Systems Engineering for Orion MPCV Artemis 3, including prototyping ground test, regression, and verification capabilities.
• Perform simulation software verification and test activities, including developing test procedures, test cases, and dry runs.
• Track requirements to code and identify applicable test cases when code changes occur.
• Develop user interfaces to support tester access and real-time status tracking.
• Coordinate with the DOORS team to interface the internal CM tracking system with IBM Rational DOORS.
• Develop malfunction scenarios for crew training in support of future Artemis missions.
• Provide enhancements and defect resolution to SOC simulation architecture, including graphics, audio, and missionspecific model data updates.
• Deliver monthly status reports on all assigned tasks.
