Mechanical Engineer - Actuators

The role

This person will design and integrate mechanical systems for high-performance robotic actuation. They will contribute to actuator development from early concepts through prototyping, testing, and manufacturing readiness.

What you will do

• Design and release actuator components and assemblies
• Deliver CAD models, engineering drawings, BOMs, and tolerance definitions
• Improve actuator performance through prototyping, testing, and failure analysis
• Integrate mechanical, electrical, sensing, and electromagnetic components
• Support the transition of designs from prototypes to production-ready hardware
• Work with electric motors and electromagnetic components regarding critical interfaces

Required qualifications

• Bachelor's or Master's degree in Mechanical Engineering or a related technical field
• 7 - 10 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

Nice to have

• 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

Benefits

• Comprehensive medical, dental, and vision coverage
• Generous paid time off, company holidays, and parental leave
• 401(k) plan with company match (100% on the first 3% of contributions, 50% on the next 2%)
• 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
• Onsite snacks and catered lunches
