Space is a critical domain, connecting our technologies, our security and our humanity. While others view space as a destination, we see it as a realm of possibilities, where we can do more — we can innovate, invest, inspire and integrate our capabilities to transform the future. At Lockheed Martin Space, we aim to harness the full potential of space to cultivate innovation, reduce costs, and push the boundaries of what technology can achieve. We're creating future-ready solutions, focusing on resiliency and urgency through our 21st Century Security® vision. We're erasing boundaries and forming partnerships across industries and around the world. We're advancing spacecraft and the workforce to fuel the next generation. And we're reimagining how space can connect us, ensuring security and prosperity. One of Lockheed Martin Commercial Civil Space's most successful programs is Orion, a partially reusable crewed spacecraft used in NASA's Artemis program, designed for Moon to Mars missions. NASA and its partners are developing the foundational systems needed for long-term exploration at the Moon for the benefit of all with NASA's Artemis campaign. The Orion Program is seeking software developers to support the Artemis IV mission, due to several contractual updates with NASA that will update Orion's flight software capabilities. Following the Artemis III mission that will land the first people near the Moon's South Pole, astronauts on Artemis IV will live and work in humanity's first lunar space station, Gateway, which will enable new opportunities for science and preparation for human missions to Mars. The mission will bring together an intricate choreography of multiple launches and spacecraft dockings in lunar orbit, and will feature the debut of NASA's larger, more powerful version of its SLS (Space Launch System) rocket and new mobile launcher. This position is for a Software Engineer Staff on the Orion Program within the Core Flight Software team supporting the full lifecycle of Software Engineering across 3 different missions: Artemis II, -III and -IV. This role will focus on the Timeline Vehicle Manager (TVM) flight software.
