Supplier Development Engineer- Motors and Magnets

About 1X

We’re building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back. Simple, but it’s not.

To do this right, we have to solve robotics, AI, manufacturing - at the same time, at scale, in a form factor that has to be safe enough to live with your family. If you’re inspired by this, you’ll thrive here. We’ve been at this since 2014 and we’re at the point where the hard problems are behind us and the hard work is in front of us.

NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people. We’re not demoing it - we’re shipping it. We’re excited to meet you, if this excites you.

If you’ve spent your career working on problems that matter and want to see them actually reach the world - this is that moment. We’re scaling, we’re hiring with intention, and we need people who want to build something that will genuinely change how humans spend their time - safely creating abundance for all.

The Supply Chain team at 1X is responsible for building and scaling the global supplier network that powers our humanoid robots. We work closely with Engineering, Manufacturing, Quality, and Operations to bring highly complex electromechanical systems from concept to mass production.

As part of the Supplier Development Engineering team, you will ensure our most critical suppliers are capable, scalable, and ready to support rapid product development and production growth. Your work directly impacts product performance, reliability, and our ability to successfully ramp NEO at scale.

As the Supplier Development Engineer for Motors & Magnets, you will own supplier industrialization and quality readiness for critical motion system components that enable NEO's performance. You will work across engineering, sourcing, and supplier partners to develop robust manufacturing processes, mitigate supply chain risk, and ensure motors and magnetic assemblies consistently meet 1X's performance, quality, and scalability requirements.
