Spacecraft Propulsion Engineer - Pumps

Job Description

Salary: $100,000-$175,000

Position: Spacecraft Propulsion Engineer Pumps Quantum Space

Location: Rockville, MD

Commitment: Full-time, all-in

Who Were Looking For

Quantum 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 Youll 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 Youll 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.

Additional Requirements

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.
