• Support troubleshooting and rework activities as directed by Engineering and Manufacturing leadership.

• Route, install, and secure electrical harnesses on satellite structures and subassemblies.
• Perform connector mating and demating using proper ESD and handling procedures.
• Install clamps, tie-downs, lacing, strain relief, and harness support hardware.
• Verify harness routing against drawings, schematics, and work instructions.
• Support continuity, resistance, insulation resistance, and functional checks as required.
• Ensure harnesses are protected from pinch points, sharp edges, thermal zones, and moving assemblies.
• Maintain proper bend radius, service loops, connector orientation, and separation requirements.

• Accurately complete work orders, travelers, inspection records, and build documentation.
• Photo document sealing surfaces, seals, connector mating surfaces, pins and sockets.
• Photo document and communicate nonconforming conditions.
• Record torque values, serial numbers, lot numbers, and nonconformances as required.
• Follow released drawings, procedures, redlines, and configuration-control requirements.
• Maintain traceability of flight hardware.

• Work in cleanroom environments following gowning, FOD, ESD, and contamination-control practices.
• Maintain a clean, organized, and safe work area.
• Follow all safety requirements when working around pressurized systems, chemicals, tools, and flight hardware.
• Support hazardous operations only when properly trained and authorized.
• Use PPE and calibrated equipment as required.

• High school diploma, GED, trade school certificate, or equivalent hands-on experience.
• 3+ years of experience in aerospace, satellite, aircraft, automotive, defense, or high-reliability manufacturing.
• Experience reading and following:
• Engineering drawings
• Work instructions
• Schematics
• Assembly procedures
• Assembly specifications
• Hands-on experience with mechanical assembly and electrical harness installation.
• Ability to use common hand tools, torque wrenches, calipers, multimeters, and inspection tools.
• Strong attention to detail and ability to work with flight or high-value hardware.
• Ability to work independently and as part of a cross-functional team.
• Comfortable working in a cleanroom or controlled manufacturing environment.

• Mechanical assembly
• Harness routing and installation
• Torque application
