Interplanetary Trajectory and Maneuver Design Engineer - KinetX

Littleton, CO; Remote

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 multiple NASA lunar missions in development and additional private missions on our manifest, we pride ourselves in supporting NASA, 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.

KinetX Aerospace, a subsidiary of Intuitive Machines, is a trusted engineering services and product company specializing in space navigation, flight dynamics, mission operations, communications, and systems engineering. As the first private company qualified by NASA for deep-space navigation, KinetX has supported some of the world’s most complex planetary missions, including MESSENGER, New Horizons, OSIRIS-REx, Lucy, and LunaH-Map. With a proven record spanning Earth-orbiting, suborbital, commercial, international, and deep-space missions, KinetX provides end-to-end expertise from early mission design through flight operations. Its core capabilities include navigation and mission systems development, optical navigation, orbit determination, maneuver design, trajectory optimization, and constellation design and maintenance. Combined with Intuitive Machines’ spacecraft, network, and mission-operations capabilities, KinetX helps build, connect, and operate resilient space infrastructure for sustained exploration, advanced deep-space constellations, and communications networks.
