Working closely with propulsion, mechanical, systems, manufacturing, and test engineering teams, you will help deliver reliable, flight-ready propulsion systems supporting national security, civil, and commercial space missions. This position is ideal for a technician who enjoys working directly with hardware, solving technical challenges, and contributing to the successful execution of spacecraft programs in a fast-paced development environment.

Where You'll Make an Impact

• Perform assembly, integration, and test (AI&T) activities for development and flight spacecraft propulsion systems and components
• 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.
