About Humanoid
Here at Humanoid, we believe in a future where robots amplify human potential. That’s why we’ve set out on a mission to build the world’s most capable, commercially-scalable, and safe humanoid robots. We’re bringing that mission to life with HMND-01 Alpha - our rapidly developed humanoid platform now running in real industrial pilots - and we’re growing the team to take it even further.
About The Role
We're looking for a hands-on Tech/Prototyping Engineer to build, assemble and maintain hardware prototypes for the end effectors on our robots and the human-worn devices operators use to interface with them. You'll run our prototyping shop, build and maintain test rigs, and support hardware testing and trial sessions — turning CAD files and BOMs into working units, fast. This is a high-paced environment where turnaround is tight and your work directly shapes what the design team builds next.
What You'll Do
- Build Prototype Hardware: Build, assemble and maintain prototype hardware from CAD/BOM through to working units.
- Operate Workshop Equipment: Operate 3D printers, CNC and general workshop tools to produce prototype parts quickly and to spec.
- Prototype with MCUs: Quickly wire up and prototype with MCU platforms such as ESP32 and Raspberry Pi to support test rigs and hardware validation.
- Build & Run Test Rigs: Build, set up and run test rigs and validation jigs for durability, calibration and functional testing.
- Support Hardware Testing: Support hardware testing, internal trials and demo sessions, providing hands-on troubleshooting and repair.
- Turn Around Fast: Deliver prototype builds within tight timelines to keep pace with rapid design-iteration cycles.
- Manage the Shop: Maintain an organised prototyping shop and parts inventory, including fasteners, connectors and components.
- Feed Back to Design: Document build issues and feed practical build, assembly and serviceability feedback directly into design decisions.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What We're Looking For
- Background in mechanical/mechatronic engineering, technician training, or equivalent hands-on hardware experience, with 2-4 years' experience prototyping physical hardware or robotics products.
- Practical skills with 3D printing, hand tools, basic machining, soldering and cable/harness assembly.
- Ability to prototype quickly with MCU platforms (e.g. ESP32, Raspberry Pi and similar), plus basic breadboarding and circuit assembly skills.
- Comfortable reading CAD drawings and BOMs and translating them into a physical build; any level of CAD design capability is a plus.
- Experience building test rigs and supporting hardware testing, trials or demos of prototype hardware.
- A practical, get-it-working mindset with good organisational habits, comfortable in a high-paced, iterative environment.
