Spacecraft Mission 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 Mission 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.

• 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

• B.S. in Mechanical Engineering, Aerospace Engineering, Physics, or similar field (M.S. preferred)
• 10+ 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

• 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

• Requirements and configuration tools (Jama, DOORS, JIRA, Confluence)
• CAD familiarity (Creo or Solid Works) and strong engineering intuition across thermal, structural, and fluids domains
• Mission analysis and engineering programming skills (Python or MATLAB) strongly valued

• 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

To comply with U.S. Government space technology export regulations, including ITAR, applicants must be a U.S. citizen, lawful permanent resident, protected individual per 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State.
