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.

Who We're Looking For

We are seeking a technically skilled and hands-on Electrical Engineer II to support the development of specialized spacecraft electronics for next-generation Ranger missions. In this role, you will contribute to the design, development, integration, qualification, and flight delivery of high-reliability avionics and spacecraft electronics supporting long-duration, high-mobility space missions.

Working closely with systems, mechanical, thermal, RF communications, FPGA, software, and integration engineers, you will help develop flight-ready electronics from early concept through spacecraft integration and launch. This position is ideal for an engineer who thrives in a fast-paced development environment and enjoys solving complex technical challenges while building hardware that flies.
