Mechanical Engineer - Actuators
Kind Humanoid
Job description
About 1X
We’re an AI and robotics company based in Palo Alto, California, on a mission to build a truly abundant society through general-purpose robots capable of performing any kind of work autonomously.
We believe that to truly understand the world and grow in intelligence, humanoid robots must live and learn alongside us. That’s why we’re focused on developing friendly home robots designed to integrate seamlessly into everyday life.
We’re looking for curious, driven, and passionate people who want to help shape the future of robotics and AI. If this mission excites you, we’d be thrilled to hear from you and explore how you might contribute to our journey.
Role Overview
We are looking for a Mechanical Engineer to support the design, integration, and iteration of robotic actuators. In this role, you will work closely with electrical, control, and test engineers to develop robust mechanical designs that can be prototyped, tested, and eventually manufactured.
You will contribute to both concept development and viability decisions and day-to-day execution, including CAD design, detailed drawings, tolerance definition, and support of assembly and testing. This role also interfaces closely with electric motors and electromagnetic components, and curiosity about electromagnetic effects on mechanical design is strongly encouraged.
Responsibilities
Design and integrate mechanical components and assemblies for robotic actuators
Create and maintain CAD models, drawings, and BOMs
Define tolerances, fits, and interfaces for actuator components
Support prototyping, assembly, and iteration of actuator hardware
Work closely with electrical engineers on packaging, clearances, and integration constraints
Consider electromagnetic interfaces (air gaps, magnets, laminations, sensors) in mechanical designs
Support testing by updating designs based on test feedback and failures
Help maintain mechanical documentation and revision control
Contribute to DFM/DFA considerations as designs mature
Job requirements
Requirements
Bachelor’s or Master’s degree in Mechanical Engineering or a related field
2–5 years of experience in mechanical design or related roles
Strong CAD skills and experience producing manufacturing drawings (Solidworks, Onshape, Inventor, …)
Understanding of mechanical fundamentals such as tolerances, fits, and materials
Curiosity about electric motors and electromagnetic effects in electromechanical systems
Hands-on mindset and willingness to support builds and testing
Ability to work effectively in a multidisciplinary engineering team
Nice to Have
Experience with electromechanical systems or actuators
Basic familiarity with electric motors or electromagnetic components
Exposure to rapid prototyping and iterative design cycles
Familiarity with bearings, gears, shafts, and structural components
Experience supporting hardware through testing and iteration
Benefits & Compensation
Salary Range: $107,700 - $161,500 + Equity
Health, dental, and vision insurance
401(k) with company match
Paid time off and holidays
