• Perform fit checks, torque applications, bonding, fastener installation, and precision alignment operations.
• Assist with electrical and mechanical integration activities, including cabling, routing, and subsystem mating.
• Support functional and environmental testing (vibration, thermal, leak, or vacuum testing) under engineer direction.
• Document build processes, integration steps, and test data accurately in accordance with company procedures.
• Identify and report non-conformances, assist in rework, and support troubleshooting activities.
• Maintain assembly tooling, fixtures, and test equipment in calibrated and operational condition.
• Follow all ESD, FOD, and safety procedures to ensure a controlled and compliant work area.
• Work collaboratively with mechanical, electrical, and test engineers to meet program goals and schedules.

What It Takes

• 2+ years of hands-on experience in mechanical assembly, integration, or testing (aerospace, defense, or high-tech manufacturing preferred)
• Strong ability to interpret engineering drawings, schematics, and work instructions
• Proficient with hand tools, torque wrenches, precision measuring instruments, and test equipment
• Experience working in a cleanroom or controlled environment a plus
• Familiarity with basic mechanical and electrical systems and safe handling of flight or precision hardware
• Strong attention to detail, documentation accuracy, and adherence to procedures
• Ability to lift 25-50 lbs and perform repetitive assembly tasks safely and efficiently
• U.S. citizenship or permanent residency (if required by contract)

Nice-to-Have Experience

• Experience supporting U.S. Space Force, Space Systems Command (SSC), Space Development Agency (SDA), AFRL, NASA, NRO, OSD, or other federal space and defense customers
• Experience pricing aerospace, defense, intelligence, or space-related programs
• Familiarity with Earned Value Management (EVM), program finance, and cost analysis methodologies
• Experience supporting strategic captures, competitive assessments, and bid/no-bid decisions
• Knowledge of FAR, DFARS, Cost Accounting Standards (CAS), and government contracting regulations
• Experience supporting proposal efforts involving advanced technology development, spacecraft, launch, or defense systems
• Experience developing and implementing pricing tools, templates, and process improvements
• MBA, CPA, CFA, or other relevant professional certifications

What You’ll Get

• Experience assembling or testing aerospace flight hardware or satellite subsystems
• Knowledge of mechanical fasteners, adhesives, and torque specifications
• Experience with environmental testing, such as vibration, shock, or thermal vacuum
• Familiarity with data collection systems and test instrumentation
• Certification in IPC, NASA-STD-8739, or equivalent assembly standards is a plus
• Compensation – Competitive salary, equity, and comprehensive benefits including medical, dental, vision, generous leave, FSA, 401(k) matching, and equity sharing

Location: Rockville, MD

Base Pay: $25.00 to $30.00 per hour
