• Perform crimping, soldering, shielding, and connector assembly to spaceflight standards
• Work with Micro-D, Nano-D, MIL-DTL-38999, and similar flight connectors
• Execute proper shielding terminations, lacing, strain relief, and routing
• Inspect and test harnesses (continuity, shorts, workmanship) prior to delivery
• Maintain ESD, FOD, and cleanliness requirements appropriate for flight hardware
• Generate clean as-built documentation

Required Experience

• Prior experience building spaceflight or flight-qualified harnesses (satellite, launch vehicle, or similar)
• Working knowledge of NASA-STD-8739.4, IPC/WHMA-A-620 Class 3, or equivalent
• Proven ability to build harnesses independently
• Experience with shielded cables, twisted pairs, coax, and high-density connectors
• Electrical soldering and rework
• Strong ability to read and execute wiring diagrams and pinouts accurately

Nice to Have
