Mechanical Design Engineer

ABOUT THE ROLE Join a small, hands-on hardware team developing autonomous robots for industrial environments. You will take mechanical subsystems from initial concept through working prototypes, helping turn robotic systems into practical infrastructure for data centre operations. WHAT YOU'LL DO - Own mechanical subsystem design from early sketches through prototyping and iteration, selecting suitable materials, tolerances, and manufacturing methods. - Design parts and assemblies in CAD, using hand calculations and FEA to guide decisions and support rapid prototyping. - Build and iterate on hardware using 3D printers, CNC equipment, and shop tools. - Integrate mechanical designs with motors, sensors, electronics, and actuators on robotic arms and mobile platforms. - Work closely with electrical, software, and robotics teammates to deliver autonomous systems for production deployment. WHAT WE'RE LOOKING FOR - Two to five years of professional experience designing mechanical hardware for six-degree-of-freedom robot arms or comparable multi-axis robotic systems. - Experience taking physical robot prototypes from concept to working hardware, including mechanisms, joints, drivetrains, or end effectors, and shipping robotics hardware on a startup or small team. - Proficiency with SolidWorks, Fusion 360, Onshape, or equivalent CAD tools. - A bachelor's degree in Mechanical Engineering or a related field. - Hands-on fabrication experience with 3D printing, CNC machining, and shop tools, in addition to CAD and simulation work. - Experience integrating mechatronic systems, including motors, sensors, or actuators; FEA or topology optimization experience is also relevant. - Ability to own subsystems end to end and work effectively in a fast-moving, lightly structured environment. COMPENSATION & BENEFITS Base salary: $150,000 to $250,000 annually. Visa sponsorship is not available. LOCATION On-site in San Francisco, California, United States.
