Spacecraft Systems Engineer

Who We’re Looking For
Quantum Space is redefining mobility and maneuverability in orbit. Our high-delta-V spacecraft platforms support national security, civil, and commercial missions where propulsion capability and rapid execution matter.

We are hiring a Spacecraft Systems Engineer to serve as a technical owner across spacecraft development, from early mission architecture through flight delivery. This is not a paperwork-only systems role. You will operate as a program technical lead, driving requirements, interfaces, design maturity, and verification across propulsion, structures, avionics, software, and mission operations.

We are looking for someone deeply technical, systems-minded, hardware-grounded, and comfortable leading multidisciplinary teams through high-stakes design reviews.

Where You’ll Make an Impact

• Own spacecraft-level technical execution across concept, design, integration, and flight readiness


• Lead end-to-end system architecture, requirements, and interface control across all subsystems


• Drive major trade studies (propulsion, power, mass, mission design, payload integration) with clear engineering judgment


• Serve as a key technical interface to customers, government stakeholders, and mission partners


• Lead internal and external reviews including SRR, PDR, CDR, TRR, and FRR


• Establish and enforce verification and validation strategy for both hardware and flight software


• Support hands-on spacecraft assembly, integration, environmental test, and launch campaign readiness


• Mentor engineers and raise the bar on technical rigor, execution speed, and engineering standards

What It Takes 

• B.S. in Aerospace or Electrical Engineering, Physics, or similar field (M.S. preferred)


• 3 to 12 years of spacecraft systems engineering experience on flight or flight-like hardware


• Demonstrated ownership of spacecraft-level requirements, architecture, and subsystem integration


• Experience leading technical execution through at least one major milestone (PDR or beyond)


• Strong understanding of spacecraft subsystems, especially propulsion, structures, avionics, and GNC interfaces


• Ability to operate as a technical authority in a fast-moving, build-and-fly environment


• Excellent communication skills, able to lead engineers, brief executives, and interface with customers

Strongly Preferred Experience

• Former Lead Systems Engineer, or technical lead for a spacecraft program


• Experience with DoD space programs, or national security missions


• Deep background in spacecraft propulsion systems and high-delta-V mission design


• Hands-on experience supporting integration, environmental test, and flight operations


• Familiarity with mission assurance, risk management, and technical standards enforcement


• Active clearance or eligibility is a plus

Tools and Technical Breadth

• Requirements and configuration tools (Jama, DOORS, JIRA, Confluence)


• CAD familiarity (Creo or SolidWorks) and strong engineering intuition across thermal, structural, and fluids domains


• Mission analysis and engineering programming skills (Python or MATLAB) strongly valued

Why Quantum Space

• Build spacecraft that actually fly, rapidly and repeatedly


• Own real technical authority, not just process


• Work with a team pushing the frontier of high-mobility space logistics


• Competitive compensation, equity, and top-tier benefits including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity sharing

Location: Rockville, MD

Base Salary: $110,000 to $220,000
