Position
: Spacecraft Propulsion Engineer – Pumps – Quantum SpaceLocation: Rockville, MDCommitment: Full-time, all-inWho We’re Looking ForQuantum Space is building highly maneuverable, long-duration spacecraft that require advanced propulsion systems. We are seeking a Spacecraft Propulsion Engineer – Pumps to lead the design and integration of pump-fed fluid systems used in our next-generation in-space vehicles.You will work hands-on with a team developing high-reliability pump solutions for storable bipropellant applications.
This role requires deep technical expertise in turbomachinery, thermal and structural constraints, and component integration for spaceflight.Where You’ll Make an Impact
- Analyze and support the development of propellant pumps and supporting systems for spacecraft propulsion.
- Develop requirements and evaluate system trade studies for pump-fed bipropellant propulsion systems.
- Validate pump CAD models and drawings using Creo.
- Support structural, thermal, and rotordynamic analyses.
- Build and validate dynamic pump models in larger system-level dynamic analyses.
- Interface with vendors and internal teams to manage pump development, testing, and delivery.
- Lead or support component and system-level test planning and execution, including hot-fire test support.
- Collaborate with systems, mechanical, fluid, and thermal teams to ensure reliable integration of pump-fed architectures.
What It Takes
- BS in Mechanical, Aerospace, or a related engineering field.
- 5+ years of experience developing propulsion or turbomachinery components for aerospace applications.
- Direct experience in design, analysis, or test of fluid pumps, impellers, seals, or similar rotating machinery.
- Knowledge of cavitation, NPSH requirements, and priming strategies for pump systems.
- Proficiency in Creo and Windchill for detailed modeling and system layout.
- Experience leading supplier interactions or internal development of flight hardware.
- Familiarity with test instrumentation, flow and pressure measurement, and data analysis.
- Strong cross-disciplinary communication skills.
What You’ll Get
- Ownership – Take the lead on developing spacecraft pump-fed propulsion solutions.
- Innovation – Push the envelope of maneuverability and mission duration through advanced hardware.
- Impact – Help define propulsion capabilities for high-priority cislunar and deep space missions.
- Growth – Join a fast-paced team with technical and leadership opportunities.
- Compensation – Competitive salary, equity, and comprehensive benefits, including medical, dental, vision, generous leave, FSA, 401(k) matching, and equity sharing.
