Execute hazardous spacecraft fueling and propellant handling operations in accordance with approved procedures, safety protocols, and operational requirements

Support propulsion hardware integration, verification, qualification, and mission readiness activities throughout the spacecraft development lifecycle

Troubleshoot propulsion hardware, fluid systems, and test equipment while supporting anomaly investigations and root-cause analysis

Provide manufacturing, integration, and testability feedback to engineering teams to improve propulsion system designs and production efficiency

Perform leak checks, pressure testing, fluid system verification, and propulsion subsystem functional testing

Support spacecraft assembly, integration, environmental testing, launch campaign preparations, and mission operations as required

Maintain accurate build records, test documentation, and hardware configuration in accordance with established quality standards

Operate safely and effectively within a fast-paced, high-reliability spacecraft development environment

Contribute to continuous improvement initiatives that strengthen propulsion manufacturing, integration, and testing processes

What It Takes

High school diploma or GED (technical certification or associate degree preferred)

3+ years of experience performing assembly, integration, and test activities within the spacecraft, aerospace, automotive, defense, or other high-reliability manufacturing industries

Demonstrated ability to independently execute assigned tasks with minimal supervision

Strong troubleshooting and mechanical problem-solving skills

Experience interpreting engineering drawings, work instructions, and technical procedures

Familiarity with precision mechanical assembly techniques, fluid systems, and hand and power tools

Strong attention to detail and commitment to quality and safety

Ability to work effectively within multidisciplinary engineering and production teams

Comfortable operating within a fast-paced, hands-on development environment

Nice-to-Have Experience

Hands-on experience performing spacecraft propulsion Assembly, Integration, and Test (AI&T) activities

Experience supporting spacecraft fueling and hazardous propellant handling operations

Experience performing semi-automated tube welding and fluid system fabrication

Experience reviewing, interpreting, and executing spacecraft AI&T procedures

Experience performing leak checks, pressure testing, proof testing, and fluid system verification

Experience operating CNC equipment to machine aerospace-grade components

Experience creating or interpreting CAD models, engineering drawings, and mechanical assembly documentation

Familiarity with cleanroom operations, hazardous operations, and aerospace quality standards

What You'll Get

Ownership – Contribute directly to the development, integration, and operation of mission-critical spacecraft propulsion systems

Innovation – Support advanced propulsion technologies enabling next-generation space mobility and maneuverability

Impact – Help deliver reliable, flight-ready propulsion hardware supporting national security, civil, and commercial space missions

Growth – Join a collaborative engineering and production team at the center of spacecraft development, integration, 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

Hourly Range: $24-48/hr

The 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, critical skills, certifications, 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.
