Prototype Wire Harness Technician

About Humble Robotics

Working at Humble Robotics means taking on the biggest change in ground transportation in decades. We’re building an autonomous, zero-emissions hauler that dramatically lowers the cost of freight with groundbreaking vision-based AI, designed for today’s global logistics network.

We’re a fast-moving, close-knit team of AV industry veterans and innovative thinkers. We don’t believe culture can be engineered – but when it falls into place, it’s a once-in-a-lifetime adventure.

Progress has never felt so present.

You’ll build the electrical nervous system of our autonomous trucks — and own the lab it comes out of. As our senior technician, you’ll fabricate high-voltage EV cables, build low-voltage and data harnesses (CAN, automotive Ethernet, coax/FAKRA), rework PCBs alongside the engineers who designed them, and run the electrical lab and wire-harness bench as your own domain — layout, tooling, stock, and standards.

Your workmanship goes straight onto prototype vehicles, and your fingerprints will be on every truck we ship.

• Fabricate, modify, and repair vehicle wiring harnesses — high-voltage EV cabling (shielded HV cable, HV connectors, HVIL), low-voltage power/signal (12/24/48V), and high-speed data (CAN/CAN-FD, LIN, automotive Ethernet, coax/FAKRA, GMSL) with proper shielding, impedance, and routing practices
• Perform PCB rework and prototype support: fine-pitch SMD and through-hole soldering, hot air rework, component replacement, and connector rework with ESD-safe handling
• Support basic board debug: continuity checks, power rail validation, and bring-up measurements
• Build and maintain lab and vehicle test benches — harnessed rigs for sensors/compute/power, relay/fuse boxes, interconnect panels, and instrumentation setups (power supplies, loads, scopes, DMMs)
• Route and dress cables in vehicles and benches: loom/overbraid, heat shrink, labeling, and connector serviceability for rapid iteration
• Troubleshoot electrical integration issues in vehicles and benches; propose fixes and improvements
• Maintain build records (as-built notes) and organize parts/tools
• Fabricate simple brackets, enclosures, and mechanical fixtures as needed

• 3+ years hands-on experience in automotive, robotics, or aerospace lab environments or prototype shops (or equivalent practical experience)
• Strong harnessing skills: crimping, pin extraction, splicing, shielding/grounding, strain relief, and proper automotive routing practices
• Experience with common connector families (Deutsch, TE, Amphenol, Molex) and backshells/boots
• Solid soldering and rework fundamentals: through-hole, connector, and cable repair with ESD-safe handling
• Comfortable reading schematics, board docs, and using a DMM/scope for basic checks
• Able to wire safe power distribution (fusing, relays/contractors) with tidy, repeatable setups
• High attention to detail, labeling, documentation, and workmanship standards
• Eligible to work in the United States

• High-voltage vehicle or EV experience (contractors, precharge, HVIL concepts, HV connectors, safe routing practices)
• Experience with automotive networks (CAN/LIN, automotive Ethernet) and coax-based sensor wiring
• Familiarity with harness documentation tools (basic CAD, wiring diagrams, pinout tables) and maintaining ECO-style updates
• Light fabrication skills (drill press, 3D printing, simple sheet metal) for fixtures and enclosures
• Fine-pitch SMD and hot-air rework on dense boards
• IPC-A-610 / IPC/WHMA-A-620 or HV safety certification (or the experience to earn one quickly)
• Experience supporting rapid prototype vehicles and field deployments
• Comfortable working around vehicles, lifting typical lab equipment, and following ESD and…
