Electrical Engineer 3 / 4 - Spacecraft Programs

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 an Electrical Engineer III / IV to support our Spacecraft Programs by leading the design, development, integration, and testing of spacecraft Avionics, Electrical Power, or Communications subsystems. This role is intended for an experienced engineer capable of owning subsystem architecture, interface definition, integration planning, verification, and flight readiness across complex spacecraft programs.

You will collaborate with systems, propulsion, thermal, mechanical, GNC, flight software, manufacturing, and AI&T teams to deliver reliable flight hardware for next-generation Ranger spacecraft.

Where You’ll Make an Impact

• Own the end-to-end development of a spacecraft electrical subsystem (Avionics, Power, or Communications) by deriving requirements, performing subsystem analyses, executing technical trade studies, and defining subsystem architectures.
• Resolve complex integration challenges and make critical system-level technical decisions throughout spacecraft development.
• Author and maintain Interface Control Documents (ICDs/EICDs), requirements, test procedures, and technical documentation.
• Support spacecraft AI&T, environmental testing (TVAC, vibration, EMI/EMC), launch campaigns, and anomaly resolution.
• Coordinate suppliers, hardware vendors, manufacturing partners, and schedule-critical deliveries.
• Participate in SRR, PDR, CDR, TRR, FRR, and other technical reviews.
• Mentor junior engineers (Level IV expected to provide technical leadership).

What It Takes

• S. in Electrical Engineering or related technical discipline (M.S. preferred).
• Engineer III: typically 7+ years of relevant spacecraft electrical engineering experience.
• Engineer IV: typically 10+ years of progressively responsible spacecraft electrical engineering experience with demonstrated technical leadership.
• Experience in Avionics, Electrical Power Systems, RF Communications, or related spacecraft electrical subsystem development.
• Experience with spacecraft interfaces including RS-422/485, LVDS, SpaceWire, Gigabit Ethernet, CAN, SPI, I2C, and Discrete I/O.
• Experience developing subsystem requirements, ICDs, integration plans, and verification documentation.
• Strong systems engineering mindset, troubleshooting ability, and cross-functional collaboration skills.
• Comfortable working in fast-paced spacecraft development environments.

Nice-to-Have Experience

• Spacecraft mission operations or long-duration mission experience.
• Radiation, reliability, fault tolerance, EMI/EMC, and EEE parts knowledge.
• Cadence, Altium, OrCAD, LTSpice, or similar ECAD/simulation tools.
• FPGA-based systems including hardware and VHDL/Verilog design
• Python scripting, automation, and hardware test development.
• National security or defense-related spacecraft programs.
• Experience leading multidisciplinary engineering teams (Level IV).
