Description

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.
Where You'll Make an Impact

• 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.

What It Takes

• 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.

Nice-to-Have Experience

• 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.

What You'll Get

• 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.
