Spacecraft Systems Engineer

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.

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.

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

Bachelor's degree in Aerospace Engineering, Electrical Engineering, Physics, or a related technical field (Master's degree preferred)

3–12 years of spacecraft systems engineering experience supporting flight or flight-like hardware

Demonstrated experience owning spacecraft-level requirements, architecture development, subsystem integration, and technical execution

Experience leading technical development through at least one major spacecraft design milestone (PDR or later)

Strong understanding of spacecraft subsystems including propulsion, structures, avionics, GNC, power, thermal, and software interfaces

Experience developing system requirements, interface control documentation, verification plans, and technical baselines

Ability to serve as a technical authority within a fast-paced spacecraft development environment

Excellent analytical, problem-solving, communication, and cross-functional leadership skills

Ability to communicate effectively with engineers, executive leadership, customers, and government stakeholders

Ownership – Lead the technical development of advanced spacecraft from mission concept through launch and flight operations

Innovation – Help develop next-generation spacecraft that redefine mobility and maneuverability in space

Impact – Work on mission-critical programs supporting national security, civil, and commercial space customers

Growth – Join a collaborative engineering team focused on rapid execution, technical excellence, and continuous innovation

Compensation – Competitive salary, equity, and comprehensive benefits including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity sharing

The salary range for this role is an estimate based on a wide range of compensation factors. Actual salary offer may vary based on (but not limited to) work experience, education and/or training, critical skills, and/or business considerations. Highly competitive equity grants are included in the majority of full-time offers and are considered part of Quantum Space's total compensation package.
