Spacecraft Systems Engineer

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 highly technical and systems-minded Spacecraft Systems Engineer to serve as the technical owner across spacecraft development, from early mission architecture through flight delivery. In this role, you will lead spacecraft-level systems engineering activities, driving requirements development, interface management, design integration, and verification across propulsion, structures, avionics, software, guidance, navigation and control (GNC), and mission operations.

You will play a critical role in ensuring technical excellence throughout the spacecraft lifecycle while partnering closely with multidisciplinary engineering teams, program leadership, customers, and mission stakeholders. This position is ideal for an engineer who combines deep spacecraft systems expertise with strong technical leadership and a passion for building and flying innovative space vehicles.

Where You'll Make an Impact

• Own spacecraft-level technical execution across concept development, design, integration, test, and flight readiness
• Lead end-to-end system architecture, requirements development, interface management, and configuration across all spacecraft subsystems
• Conduct and lead system-level trade studies involving propulsion, power, mass properties, mission design, payload integration, and overall vehicle performance
• Serve as the primary technical interface with customers, government stakeholders, mission partners, and internal program leadership
• Lead major engineering reviews including System Requirements Review (SRR), Preliminary Design Review (PDR), Critical Design Review (CDR), Test Readiness Review (TRR), and Flight Readiness Review (FRR)
• Develop and execute spacecraft verification and validation strategies for both flight hardware and software
• Support spacecraft assembly, integration, environmental testing, launch campaign activities, and mission readiness
• Collaborate across propulsion, avionics, structures, software, GNC, manufacturing, and mission operations teams to ensure successful system integration
• Mentor engineers while promoting technical rigor, rapid execution, and engineering best practices
• Support multiple spacecraft development efforts in a dynamic, fast-paced engineering environment
• Contribute to continuous improvement initiatives that strengthen systems engineering processes, design methodologies, and technical standards
