Job Description

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.

Job Responsibility

  • 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

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

What we offer

  • Health, dental, and vision insurance
  • 401(k) with company match
  • Paid time off and holidays
  • Equity
