Electrical Engineer III - Advanced Programs

Who We’re Looking For

Quantum Space is redefining mobility and maneuverability in space. Our high-mobility spacecraft platforms support national security, civil, and commercial missions with unmatched flexibility and propulsion capability. We build fast and iterate quickly. We are seeking a motivated and technically capable Electrical Engineer to support the design, development, integration, and testing of spacecraft electrical systems and defense-related space technologies. In this role, you will contribute to spacecraft avionics, communications, power systems, embedded electronics, and hardware integration activities while collaborating closely with multidisciplinary engineering teams. You will work hands-on with cutting-edge aerospace hardware in a fast-paced environment supporting national security and spaceflight missions.

We are seeking an Electrical Engineer III to lead the development of specialized spacecraft electronics hardware supporting next-generation Ranger missions. This role is intended for an experienced hardware engineer capable of taking conceptual designs from early prototyping through flight-qualified delivery while operating across multidisciplinary spacecraft development efforts.

You will work closely with systems, mechanical, thermal, propulsion, FPGA, and flight software teams to develop high-reliability electronics hardware for demanding long-duration missions. This is a hands-on technical role focused on execution, hardware ownership, and rapid iteration in support of mission-critical spacecraft systems.
