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 and iterate quickly.

We are seeking a Propulsion Engineer to design, develop, and deliver innovative propulsion hardware for our next-generation spacecraft. This role offers the opportunity to own propulsion components and assemblies throughout their lifecycle, from design concepts through qualification and flight. You will work hands-on in a dynamic environment, collaborating across disciplines to enable mission success.

Where You’ll Make an Impact

• Generate 3D models and detailed drawings for propulsion components and assemblies.
• Perform design, analysis, and development tasks for propulsion subsystems.
• Own hardware from concept through manufacturing, test, and on-orbit operations.
• Validate designs through build and qualification, ensuring manufacturability and reliability.
• Collaborate with engineers and technicians across mechanical, fluids, electrical, software, test, and production disciplines.
• Interface with key suppliers and vendors to support hardware delivery.

What It Takes

• Bachelor’s degree in mechanical, aerospace, or related engineering field.
• 5+ years of mechanical design and development experience in industry.
• Proficiency in mechanical design, materials, and thermodynamics.
• CAD proficiency, with practical application of GD&T.
• Experience designing for manufacturability, including machining, assembly, and testing.
• Demonstrated success in rapid design–build–test hardware cycles.

Nice-to-Have Experience

• Direct design and development experience with aerospace mechanical systems.
• Familiarity with FEA or related analysis tools.
• Experience with electric propulsion technologies or plasma physics.
• Hands-on experience with qualification and flight hardware.

What You’ll Get

• Innovation – Work on novel propulsion technologies and help define manufacturing processes.
• Impact – See your designs fly and directly contribute to mission success.
• Growth – Opportunities for technical leadership in a fast-growing space company.
• Compensation – Competitive salary, equity, and top-tier benefits including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity sharing.
