About The Position

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.

Requirements

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
PCB rework competence: confident with fine-pitch soldering and hot-air rework on dense boards
Comfortable reading schematics, board docs, and using a DMM/scope for basic checks
Able to wire safe power distribution (fusing, relays/contactors) with tidy, repeatable setups
High attention to detail, labeling, documentation, and workmanship standards

Nice To Haves

High-voltage vehicle or EV experience (contactors, 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
Experience supporting rapid prototype vehicles and field deployments
Comfortable working around vehicles, lifting typical lab equipment, and following ESD and electrical safety procedures including HV safety practices

Responsibilities

Build, modify, and repair vehicle wiring harnesses — low-voltage power/signal (12/24/48V), high-voltage cabling, and high-speed data (automotive Ethernet, coax, CAN) 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
