Propulsion Engineer

Who We’re Looking For

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, iterate quickly, and deliver flight hardware.

We are seeking a Propulsion Engineer to contribute to the development of space‑rated propellant tanks, propulsion components, and integrated propulsion systems. This role offers hands‑on involvement across the full development lifecycle—from early design and analysis through build, test, and on‑orbit operations.

• Execute engineering tasks across the full product lifecycle, including design, analysis, build, test, and flight support.
• Support the development and delivery of propulsion hardware under the guidance of senior engineers.
• Collaborate with cross‑disciplinary teams in a fast‑paced, mission‑driven environment.
• Apply sound engineering practices to solve propulsion challenges and meet technical and program requirements.

• Bachelor’s, Master’s, or Ph.D. in Aerospace or Mechanical Engineering.
• 3+ years of experience working with propulsion systems or closely related hardware.
• Demonstrated ownership of defined engineering tasks or subsystems.
• Familiarity with common engineering analysis tools and methods.
• Ability to work independently while effectively integrating with a larger team.
• Adaptability operating in an evolving development environment.
• Strong commitment to continuous learning and technical growth.

• Experience working in a fast‑paced startup or rapid development environment.
• Exposure to propulsion analysis using tools such as MATLAB/Simulink, CFD, FEA, Surface Evolver, and GFSSP.
• Experience with CAD tools and hardware design.
• Programming experience in Java, Python, Julia, and/or C++.
• Familiarity with 5S (6S) and Lean Six Sigma principles.

• Ownership – Opportunities to take responsibility for meaningful engineering tasks and hardware.
• Innovation – Hands‑on involvement in developing next‑generation propulsion systems and spacecraft.
• Impact – See your work fly on unique, high‑profile missions.
• Growth – A clear technical growth path within a fast‑growing space company.
• Compensation – Competitive salary, equity, and comprehensive benefits, including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity participation.
