About The Position

At Advanced Space, we're enabling humanity's return to the Moon and building the technologies that will take us to Mars and beyond. We're looking for a Software Engineer with 5–8 years of experience to develop mission-critical ground and flight software that powers some of the most ambitious space missions in the industry. In this role, you'll design, develop, and maintain software supporting spacecraft operations, mission control systems, and advanced space technologies. You'll collaborate with multidisciplinary engineering teams to build reliable, scalable software that supports real missions—from lunar exploration to national security and commercial space programs. We're looking for someone who enjoys solving challenging technical problems, writing high-quality software, mentoring teammates, and building systems that help shape the future of space exploration. This position is open to U.S. Citizens only. Visa sponsorship is not available. An active security clearance is preferred, or the ability to obtain a TS/SCI clearance is required.
