Job description

We are helping our client find a Mechanical Engineer to support the design, fabrication, and assembly of physical hardware systems in a hands‑on development lab.

In this role, you'll design and build mechanical components, assemble functional hardware systems, and demonstrate fabrication and assembly processes. You'll work through the full hardware development lifecycle, from design and component sourcing to fabrication, testing, and iterative improvements. Your builds and documented work will also contribute to training AI systems to better understand hands‑on physical tasks.

The ideal candidate brings strong mechanical design and fabrication experience, hands‑on assembly skills, and the ability to clearly explain technical processes while identifying opportunities to improve designs and build instructions.

Recording & Data Collection Notice

This role involves recording your work to support AI training and development. Lab cameras and screen recording on your work device will capture your activities. Depending on the project, you may also be asked to wear sensors, such as motion trackers or pressure‑sensing gloves, that collect biometric data. Before starting, you'll receive details about the recording and data collection requirements specific to your role, how your data will be protected, and the consent process.

As a Mechanical Engineer, you'll:

• Design and modify mechanical parts and assemblies using CAD software, including Onshape, SolidWorks, or similar tools.
• Fabricate components through 3D printing, post‑processing, and light shop fabrication using hand and power tools.
• Assemble mechanisms, frames, and subsystems using fasteners, bearings, belts, gear trains, and T‑slot framing.
• Verify component fit, tolerances, and assembly specifications using calipers and other precision measurement tools.
• Demonstrate and explain fabrication and assembly processes step by step, identifying design issues and inaccuracies in build instructions.
• Document build procedures, technical findings, and assembly steps with clear written notes and photographs to support team collaboration.

Nice to have: makerspace experience, actuator or gearbox assembly, fixture design, experience teaching or training others in a shop, makerspace or lab.

Daily tasks:

• About the program We're a hands‑on hardware lab hiring skilled engineers and technicians to design, build and test real devices.
• The work follows a real hardware loop: design, source parts, assemble, test, and feed what you learn into the next iteration.
• How your work is used: your builds, demonstrations and worked examples become training data that helps AI systems understand hands‑on physical work.
• You'll also review the written and on‑screen instructions at your bench and tell us where they're wrong.
• This role involves recording, and we want you to know exactly what that means before you apply. Cameras in the lab and screen recording on your work device capture your work.
• Depending on the project, you may also wear sensors such as motion trackers or pressure‑sensing gloves, which collect biometric data.
• You'll see exactly what applies to your role, and how that data is protected, and you'll give your consent before you start.
• What you'll do Teach assembly and fabrication: demonstrate and explain, step by step, how each part is made and how it goes together, and say where the design or the build instructions are wrong.
• Design and modify parts and assemblies in CAD, then make them: 3D print, post‑process, and do light shop fabrication. Assemble mechanisms, frames and subsystems by hand (fasteners, bearings, belts, gear trains, T‑slot framing), and check fit and tolerance by measurement. Write clear build notes with photos for the rest of the team.

Required skills

• Requirements 2+ years of hands‑on experience in both mechanical design and fabrication: you've designed parts and built them yourself.
• Fabrication and assembly to spec: 3D printing, shop tools, torque specs, fits and tolerances, measurement.
• Can explain clearly, while you work, how a part is made and how it goes together. Strong CAD skills and a track record of building things: hardware startups, engineering teams or serious hobbyist hardware.
• Tools: CAD (Onshape, SolidWorks or similar), 3D printers, hand and power tools, calipers and measuring tools, T‑slot framing.
