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 Actuators team develops the electromechanical systems that enable NEO to move with strength, precision, and reliability. Our work spans mechanical design, electric motors, sensing, power transmission, controls integration, and hardware validation.

We work closely with electrical, controls, firmware, test, and manufacturing teams to rapidly develop actuator concepts, validate performance, and mature designs into reliable systems that can be produced at scale.

Your Charter

Design and integrate the mechanical systems that enable high-performance robotic actuation.

You will contribute to actuator development from early concepts and technical viability decisions through detailed design, prototyping, testing, and manufacturing readiness. Your work will include mechanical packaging, tolerance definition, component integration, and design iteration based on hardware test results.

You will also work closely with electric motors and electromagnetic components, ensuring mechanical designs account for critical interfaces such as air gaps, magnets, laminations, sensors, thermal behavior, and assembly constraints.

Key Outcomes

• Design and release actuator components and assemblies that meet performance, packaging, reliability, and manufacturability requirements

• Deliver accurate CAD models, engineering drawings, BOMs, tolerance definitions, and interface documentation

• Improve actuator performance and durability through rapid prototyping, testing, failure analysis, and design iteration

• Successfully integrate mechanical, electrical, sensing, and electromagnetic components into complete actuator systems

• Support the transition of actuator designs from early prototypes into repeatable, production-ready hardware

Key Competencies

• Strong mechanical design fundamentals with the ability to create practical and manufacturable hardware

• Hands-on engineering mindset with an interest in assembling, testing, troubleshooting, and improving physical systems

• Strong mechanical intuition around tolerances, fits, materials, bearings, shafts, and structural interfaces

• Curiosity about electric motors, electromagnetic systems, and multidisciplinary actuator design

• Strong collaboration and communication skills across mechanical, electrical, controls, test, and manufacturing teams

Minimum Requirements

• Bachelor’s or Master’s degree in Mechanical Engineering or a related technical field

• 2–5 years of experience in mechanical design, product development, or a related engineering role

• Strong proficiency with CAD tools such as SolidWorks, Onshape, Inventor, or equivalent

• Experience creating production-quality engineering drawings and mechanical documentation

• Strong understanding of tolerances, fits, materials, and mechanical design fundamentals

• Hands-on experience supporting prototype assembly, testing, and hardware iteration

• Ability to work effectively in a fast-paced, multidisciplinary engineering environment

Preferred Skills

• Experience developing robotic actuators, motors, or other electromechanical systems

• Familiarity with electric motors, magnets, laminations, air gaps, encoders, or electromagnetic components

• Experience with bearings, gears, shafts, transmissions, and structural actuator components

• Exposure to rapid prototyping and iterative hardware development cycles

• Experience supporting hardware through verification testing, failure analysis, and design refinement

• Familiarity with Design for Manufacturability and Design for Assembly principles

What does a successful 1X Team Member look like?

Team members at 1X who thrive here are builders. They move fast, own their work completely, and treat time like it’s the one thing you can’t get back - because it is. They say what they mean, finish what they start, and hold themselves to a standard before anyone has to ask. We push each other to be better, and we do it with honesty and respect.

Successful engineers on the Actuators team combine strong mechanical fundamentals with curiosity across adjacent disciplines. They enjoy moving between CAD, hardware builds, testing, and cross-functional problem-solving. They learn quickly from physical systems and take ownership of improving designs until they perform reliably in the real world.
