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 – Spacecraft Programs (RF Communications) to lead RF communications subsystem development for Ranger spacecraft programs. This role is intended for an experienced spacecraft communications engineer capable of driving subsystem architecture, RF interface definition, hardware integration, and end-to-end communications system development across complex spacecraft platforms.

You will work closely with avionics, power, payload, flight software, GNC, thermal, mechanical, and systems engineering teams to develop reliable spacecraft communications architectures supporting long-duration, high-mobility missions across national security, civil, and commercial applications.
