Mechanical Engineer - Actuators

Actuators Team Member 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 Compensation Range $107,700 - $161,500 + Equity 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 Equal Opportunity Employer 1X is an Equal Opportunity Employer.
