Mechanical Engineer - Actuators

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 What does a successful 1X Team Member look like? Team members at 1X who thrive here are builders. They move fast, own their work completely, and treat time like it’s the one thing you can’t get back - because it is. They say what they mean, finish what they start, and hold themselves to a standard before anyone has to ask. We push each other to be better, and we do it with honesty and respect. Successful engineers on the Actuators team combine strong mechanical fundamentals with curiosity across adjacent disciplines. They enjoy moving between CAD, hardware builds, testing, and cross-functional problem-solving. They learn quickly from physical systems and take ownership of improving designs until they perform reliably in the real world.
