Full Job Description

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.

Who We're Looking For

We are seeking a motivated and technically driven Engineer II – Propulsion to contribute to the development of advanced propellant tanks, pumps, and next-generation spacecraft propulsion systems supporting Ranger missions. In this role, you will help design, develop, qualify, integrate, and support flight propulsion hardware that enables high-mobility spacecraft for national security, civil, and commercial space applications.

Working closely with propulsion, mechanical, systems, manufacturing, test, and flight operations teams, you will support propulsion hardware throughout the full product lifecycle—from concept development through flight operations. This position is ideal for an engineer who enjoys solving complex technical challenges, taking ownership of hardware development, and contributing directly to flight-ready spacecraft systems.

Where You'll Make an Impact

Contribute to the design, development, and qualification of propellant tanks, pumps, and advanced spacecraft propulsion systems
Execute engineering tasks across design, analysis, manufacturing, testing, qualification, integration, and flight support activities
Perform propulsion system trade studies and technical evaluations supporting spacecraft architecture decisions
Develop engineering analyses, models, and technical documentation supporting propulsion hardware development
Collaborate with multidisciplinary engineering teams to deliver propulsion hardware on schedule while meeting technical and program objectives
Support subsystem integration, environmental testing, launch campaign activities, and mission readiness
Investigate propulsion hardware anomalies, perform root-cause analysis, and implement corrective actions
Contribute to the development of propulsion engineering standards, best practices, and continuous process improvements
Support technical reviews including System Requirements Review (SRR), Preliminary Design Review (PDR), Critical Design Review (CDR), Test Readiness Review (TRR), and Flight Readiness Review (FRR)
Operate within a fast-paced development environment focused on rapid execution, technical excellence, and mission success

What It Takes

Bachelor's, Master's, or Ph.D. in Aerospace Engineering, Mechanical Engineering, or a related engineering discipline
3+ years of experience developing propulsion systems, fluid systems, or related aerospace hardware
Experience designing, analyzing, fabricating, testing, and integrating propellant tanks, pumps, or spacecraft propulsion systems
Demonstrated ability to independently execute technical work from concept through implementation while collaborating effectively with engineers, technicians, manufacturing personnel, and cross-functional stakeholders
Strong analytical, problem-solving, and communication skills
Comfortable operating in a fast-paced, iterative spacecraft development environment

Nice-to-Have Experience

Experience leading significant engineering tasks supporting the development of propellant tanks, pumps, or spacecraft propulsion systems
Experience performing Computational Fluid Dynamics (CFD) and/or Finite Element Analysis (FEA)
Experience performing performance analysis of pump-fed spacecraft propulsion systems
Experience designing, analyzing, or testing propellant management devices (PMDs)
Experience with laser welding, friction stir welding, or other advanced aerospace manufacturing processes
Experience machining aerospace-grade components using CNC equipment
Experience testing propulsion systems utilizing propellants such as hydrazine and MON-3
Experience designing gear pumps, pump motors, or other spacecraft fluid system components
Experience supporting fast-paced aerospace, defense, or commercial space programs
Experience utilizing AI-enabled engineering, modeling, or design optimization tools

What You'll Get

Ownership – Take responsibility for mission-critical propulsion hardware and systems from concept through flight
Innovation – Help develop advanced propulsion technologies enabling next-generation spacecraft mobility and maneuverability
Impact – Deliver reliable, flight-ready propulsion systems supporting national security, civil, and commercial space missions
Growth – Join a multidisciplinary engineering team where you'll contribute across propulsion development, integration, testing, and mission execution
Compensation – Competitive salary, equity, and comprehensive benefits including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity participation

Location: Rockville, MD or Hawthorne, CA

Base Salary: $110,000–$160,000

The salary range for this role is an estimate based on a wide range of compensation factors. Actual salary offer may vary based on (but not limited to) work experience, education and/or training, technical expertise, critical skills, and business considerations. Highly competitive equity grants are included in the majority of full-time offers and are considered part of Quantum Space's total compensation package.

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.
