About the Team Droyd builds autonomous robotic systems that automate repetitive manual work in real environments. We design and manufacture our hardware in-house, which means iteration, fabrication, and execution all happen under one roof. Our robots operate in production settings, which means mechanical design has to be robust, manufacturable, and tightly integrated with electronics and control systems. Our mechanical team designs the structures, linkages, and assemblies that make the robots real - this work moves fast and lives on the shop floor as much as it does in CAD. About the Role As a Mechanical Design Engineer at Droyd, you will own mechanical subsystems from first sketch through working prototype. You will design, build, break, and iterate on real hardware. This is a hands-on role. You will spend time in CAD, but also at the printer, in the shop, and on the robot, working closely with electrical, software, and robotics teams to bring systems together. This role...
