About the role

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.
Integrate motors, sensors, PCBAs, cabling, bearings, and power transmission systems into robust robotic assemblies
Hands-on builder who enjoys designing, prototyping, testing, and refining hardware

We're building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back.
NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people.
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.
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.
Design and release mechanical components and electromechanical subsystems that meet performance, reliability, and manufacturability requirements

Bachelor's or Master's degree in Mechanical Engineering or a related engineering discipline
5+ years of experience designing mechanical systems or electromechanical products
Strong proficiency with professional 3D CAD software
Experience with GD&T, tolerance analysis, and production-ready engineering documentation
Extensive experience selecting and integrating bearings into precision mechanical systems

Experience with ANSYS or equivalent structural simulation tools
Knowledge of injection molding, die casting, machining, and other high-volume manufacturing processes
Experience designing power transmission systems, robotic joints, or actuator assemblies

Comprehensive medical, dental, and vision coverage
Generous paid time off, company holidays, and parental leave
Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) options
Commuter benefits (transit and parking)
Short-term and long-term disability, and life insurance
Employee Assistance Program (EAP) for mental health, financial, and personal support

Deliver lightweight, high-strength designs through structural analysis, FEA, and rapid design iteration
Improve product quality through Design for Manufacturability (DFM), Design for Assembly (DFA), serviceability, and cost optimization
Drive hardware from concept through prototype validation, design refinement, and successful production release
Strong mechanical engineering fundamentals with exceptional structural and mechanism design capability
Strong analytical skills with the ability to balance engineering trade-offs across performance, reliability, weight, and manufacturability
Excellent collaboration across electrical, firmware, controls, manufacturing, and robotics disciplines
Ownership mindset with the ability to independently drive complex hardware development efforts
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.
