About the Job

Requirements

The candidate must have at least 3 years of hands-on experience in automotive, robotics, or aerospace lab environments or prototype shops, or equivalent practical experience.
The candidate must have strong harnessing skills, including crimping, pin extraction, splicing, shielding and grounding, strain relief, and proper automotive routing practices.
The candidate must have experience with common connector families including Deutsch, TE, Amphenol, and Molex, as well as backshells and boots.
The candidate must have solid soldering and rework fundamentals, including through-hole, connector, and cable repair with electrostatic-discharge-safe handling.
The candidate must be comfortable reading schematics and board documentation and using a digital multimeter and oscilloscope for basic checks.
The candidate must be able to wire safe power distribution using fusing, relays, and contactors with tidy, repeatable setups.
The candidate must demonstrate high attention to detail in labeling, documentation, and workmanship standards.
The candidate must be eligible to work in the United States.

Responsibilities

Fabricate, modify, and repair vehicle wiring harnesses, including high-voltage electric-vehicle cabling, low-voltage power and signal wiring, and high-speed data wiring with proper shielding, impedance, and routing practices.
Perform printed circuit board rework and prototype support, including fine-pitch surface-mount-device and through-hole soldering, hot-air rework, component replacement, and connector rework with electrostatic-discharge-safe handling.
Support basic board debugging through continuity checks, power-rail validation, and bring-up measurements.
Build and maintain lab and vehicle test benches, including harnessed rigs for sensors, compute, and power; relay and fuse boxes; interconnect panels; and instrumentation setups using power supplies, loads, oscilloscopes, and digital multimeters.
Route and dress cables in vehicles and benches using loom or overbraid, heat shrink, labeling, and connector-serviceability practices for rapid iteration.
Troubleshoot electrical integration issues in vehicles and benches and propose fixes and improvements.
Maintain build records and organize parts and tools.
Fabricate simple brackets, enclosures, and mechanical fixtures as needed.

Desired Qualifications

High-voltage vehicle or electric-vehicle experience, including contactors, precharge, high-voltage interlock-loop concepts, high-voltage connectors, and safe routing practices.
Experience with automotive networks including Controller Area Network, Local Interconnect Network, automotive Ethernet, and coax-based sensor wiring.
Familiarity with harness documentation tools, including basic computer-aided design, wiring diagrams, pinout tables, and engineering-change-order-style updates.
Light fabrication skills using a drill press, 3D printing, and simple sheet metal for fixtures and enclosures.
Fine-pitch surface-mount-device and hot-air rework on dense boards.
IPC-A-610, IPC/WHMA-A-620, or high-voltage safety certification, or experience indicating the ability to earn one quickly.
Experience supporting rapid prototype vehicles and field deployments.
Comfort working around vehicles, lifting typical lab equipment, and following electrostatic-discharge and electrical safety procedures, including high-voltage safety practices.

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.

Position Overview

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.

Responsibilities

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

Minimum Qualifications

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/contactors) with tidy, repeatable setups
High attention to detail, labeling, documentation, and workmanship standards
Eligible to work in the United States

Preferred Qualifications

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
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 electrical safety procedures including HV safety practices

Compensation

Salary ranges are determined by role, level, and location. Within the range, individual pay is determined by additional factors, including qualifications, skills, experience, and location. We also offer competitive equity compensation and benefits.

About the Company

Humble Robotics

Autonomous, cabless EV haulers for freight

Humble Robotics builds fully autonomous, cabless, battery-electric Class 8 haulers designed to move freight dock-to-dock in warehouses, railyards, and seaports, starting with shipping-container moves. The trucks navigate using 360° cameras, LiDAR, and radar, and run vision-language-action models to drive themselves, with remote operational support as part of a full-service offering. Unlike many competitors, Humble leverages a cabless, lighter-weight design for better payload efficiency, and it brings together a team with experience from Tesla, Waymo, Cruise, Google, Rivian, Apple, Uber, and Waabi. The company aims to advance the autonomy stack, launch pilots, and begin early manufacturing to support eventual public-road deployment.
