Low Voltage Wire Harness Technician

Low Voltage Wire Harness Technician

Overview

Build the electrical systems powering the next generation of autonomous vehicles and advanced test platforms. As a Low Voltage Wire Harness Technician, you will fabricate, install, test, and troubleshoot 12V/24V wire harnesses that connect computing platforms, sensors, drive-by-wire interfaces, and power distribution systems.

This hands-on, lab-based role combines precision bench fabrication with installation and validation on prototype vehicles and test benches. You will work closely with design engineers to identify build issues, document as-built configurations, support engineering changes, and improve the reliability of prototype fleets and test systems. High-voltage electrical work is strictly outside the scope of this position.

Required Skills

• At least 2 years of hands-on experience fabricating, installing, and troubleshooting low-voltage wire harnesses.
• Experience in automotive, aerospace, robotics, drone, industrial, or comparable environments.
• Ability to cut, strip, crimp, splice, shield, sleeve, label, and terminate wire harnesses.
• Hands-on experience with connectors and terminals from manufacturers such as:
• Molex
• TE Connectivity
• Deutsch
• Amphenol
• Proficiency using crimp tools, pull testers, digital multimeters, harness testers, and basic CAN tools.
• Ability to read and interpret schematics, harness drawings, pinout tables, and bills of materials.
• Strong understanding of 12V/24V electrical systems, including:
• Wire gauge selection
• Circuit protection and fusing
• Grounding
• Strain relief
• Harness routing and clearance requirements
• Familiarity with automotive data interfaces, including CAN, Ethernet, GMSL, and USB.
• Experience performing continuity, isolation, pull-force, and functional testing.
• Ability to troubleshoot opens, shorts, voltage drops, bad grounds, intermittent faults, and connector wear.
• Strong attention to detail when documenting revisions, discrepancies, root causes, and corrective actions.
• Ability to rework harnesses in accordance with Engineering Change Orders and maintain accurate revision records.
• Proactive communication skills, including the confidence to raise physical build issues and drawing discrepancies with engineering teams.
• Ability to work inside prototype vehicles and in tight or physically demanding spaces.

Nice-to-Have Skills

• IPC/WHMA-A-620 certification.
• J-STD-001 soldering certification.
• Experience with harness CAD outputs, such as Capital, RapidHarness, or CATIA Electrical.
• Familiarity with JIRA for task and ticket management.
• Experience building breakout boxes, test fixtures, instrumentation harnesses, or lab test equipment.
• Experience creating redlined drawings, pinout revisions, wire lists, and as-built documentation.
• Familiarity with Slack or similar collaboration tools.
• Experience monitoring and maintaining inventory of wire, terminals, connectors, and related lab supplies.

Preferred Education and Experience

• At least 2 years of relevant hands-on low-voltage wire harness experience.
• No specific degree or formal educational background is required.
• Practical experience with harness fabrication, vehicle wiring, electrical testing, and troubleshooting is highly valued.
• Experience supporting prototype development, engineering changes, or complex electromechanical systems is beneficial.

Other Requirements

• Work location: Onsite and lab-based in Sunnyvale, California.
• Schedule: Flexible start times between 6:00 AM and 9:00 AM; typically 45–50 hours per week.
• Overtime may be approved based on business needs.
• Approximately 15% national travel may be required to support regional vehicle testing and field activities. Potential international travel may also be available.
• Must be willing and able to travel as needed.
• Contract-to-hire opportunity with an initial 6-month term and potential transition to direct hire.
• High-voltage electrical work is strictly outside the scope of this role.
