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.

About the Team

The Tooling team builds the tools, pipelines, and infrastructure that speed up iteration and give us confidence our software works properly before it reaches physical robots. This team turns our simulator into a first-class tool that is easy to use, extensible by developers, and accurate to our robot’s unique hardware – leveraging game engine assets and expertise to accelerate the development of embodied AI.

Your Charter

Build the next generation of simulation tooling that powers robotics development at 1X. You will improve the simulator, developer workflows, and content pipelines that allow engineers to rapidly create environments, manage assets, automate testing, and validate robot behavior at scale. This role blends game engine engineering, developer tooling, technical art workflows, CI/CD infrastructure, and simulation platform development to create a world-class robotics development environment.
