Senior to Mechanical Engnieer

Overview

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 Hardware Engineering team designs and delivers the electromechanical systems that allow NEO to move, manipulate, and interact safely with the world. From structural components and precision mechanisms to complete robotic subsystems, the team owns hardware development from concept through production. Working closely with electrical, controls, firmware, manufacturing, and robotics engineers, you ll help transform ambitious ideas into robust, manufacturable products that operate reliably in real-world environments.

Design and deliver the mechanical systems that power humanoid motion.

You will own mechanical subsystems from concept through production, developing high-performance electromechanical hardware that balances strength, weight, durability, manufacturability, and cost. Through rapid prototyping, rigorous testing, and close cross-functional collaboration, you ll help build robots capable of operating reliably in homes around the world.
