Position Introduction/Key Duties

Cimarron is seeking a Human Landing System (HLS) Software Engineer 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 places you at the forefront of human spaceflight, developing the simulation systems that model critical docked operations between Orion and the Human Landing System (HLS). 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 systems engineering and SIM software development for Orion Docked Operations scope supporting HLS Interface and Functional checkout and HLS Command/Telemetry Data Path Checkout.
• Expand Orion's Target Vehicle Actuator Controller (TVAC) model to support Comm capabilities, including canned/faultable telemetry and EWCA alerts.
• Develop Orion Dynamics simulation models, including creation of an Orion vehicle HLA Federate using FOD's TSFOM interface and implementing timesync updates for incoming HLS Federate states.
• Develop FOM manager interfaces and integrate summing of Force faults and docking contact modeling in support of ITL joint testing and beyond.
• Develop Orion ECLSS simulation models covering air exchange, consumption, and crew movement scenarios.
• Configure and validate OrionHLS/Gateway RF and RUC traffic routing through Sim I/O Pump SpaceWire interfaces and NIC mappings to CCM and Orion switches.
• Provide lab and integration support, including preparation for and execution of SpaceX emulator integration in the ITL and trajectory updates.
• Deliver monthly status reports on all assigned tasks.
