Job summary

Humanoid is seeking a hands-on Prototype Engineer to build and maintain hardware prototypes for end effectors and human-worn interfaces. You will run the prototyping shop, assemble test rigs, and translate CAD/BOMs into working units in a fast-paced, iterative environment.

You’ll prototype with ESP32, Raspberry Pi and similar MCUs, work with 3D printers and CNC, and help shape the next generation of humanoid robotics through practical, on‑the‑bench engineering.

Qualifications

• Background in mechanical/mechatronic engineering or hands-on hardware experience.
• Proficiency with 3D printing, hand tools, basic machining, soldering and wiring.
• Ability to prototype quickly with MCU platforms (ESP32, Raspberry Pi) and basic breadboarding.
• Comfortable reading CAD drawings and BOMs and translating them into a physical build.
• Experience building test rigs and supporting hardware testing.
• A practical, get-it-working mindset in a fast-paced environment.

Responsibilities

• Build, assemble and maintain prototype hardware from CAD/BOM to working units.
• Operate 3D printers, CNC and workshop tools to produce parts quickly and to spec.
• Prototype with MCU platforms to support test rigs and hardware validation.
• Build, set up and run test rigs and validation jigs for durability, calibration and functional testing.
• Support hardware testing, trials and demos, providing hands-on troubleshooting and repair.
• Deliver prototype builds within tight timelines to keep pace with rapid design-iteration cycles.
• Maintain an organized prototyping shop and parts inventory.
• Feed practical build and assembly feedback into design decisions.
