Mechanical Engineer (Robotics & Electromechanical)

About Overlay Overlay is building the world's first intelligent makeup robot, reimagining beauty application through robotics, perception, and design. As a venture-backed, pre-launch startup, we're defining a new category of personal robotics at the intersection of self-expression and engineering. We're a small team inventing what doesn't yet exist and turning it into something beautiful. What You'll Own Own mechanical design of robotic and electromechanical subsystems, from concept through build Design motion systems: select and size motors, gearboxes, bearings, sensors and actuators Design cable management and routing through moving assemblies Run FEA and tolerance analysis, and turn results into design changes Design plastic and machined parts for manufacturing (injection molding, CNC, sheet metal) Design and build test fixtures; plan and run validation with clear pass/fail data Create assembly and fabrication-ready drawings Work with firmware, electrical, robotics and vendor teams to keep interfaces and specs clear Embody our company values of ownership, velocity and craft What We're Looking For 4+ years designing robotic or electromechanical products, through at least one build SolidWorks and FEA Motor, actuator and drivetrain sizing Cable routing and packaging in moving assemblies DFM for injection molding and machining Test fixture design and validation testing Working knowledge of ASME Y14.5 / GD&T Thrive in a small, resource-conscious startup where the job is to invent, build and ship Bonus Points Robot arms, consumer robotics, or medical/personal-care devices Experience working with contract manufacturers or vendors in Asia Metrology experience: CMM, laser tracker or stereo camera Prototype bring-up, 3D printing, machining Interesting side projects Who You Are Mission-driven: excited to build a new category of personal robotics that works on real people Hands-on: you like building, testing and fixing hardware yourself Energized by working in person with a small team in our Oakland office High ownership, and comfortable moving fast with incomplete information Culture and Values Move Fast, Move Smart: Act quickly, but with clear thinking and good judgment.
