We design and build custom machines, robotic cells, and factory automation for aerospace, automotive, and precision manufacturers. Projects move fast: concept to running machine in weeks, not years. ### What you'll do - Design complete custom machines and robotic cells: frames, fixtures, grippers, part feeders, guarding, and integration with CNC machines and robots. - Select off-the-shelf components (Misumi, SMC, Festo, THK, motors and gearboxes) and size actuators, linear motion, and pneumatics. - Design custom parts to be machined in-house, keeping them simple and fast to make and assemble. - Produce 3D models, drawings, and BOMs in SolidWorks quickly, then support build, debug, and installation on the floor. - Work closely with controls engineers on sensors, PLC I/O, and motion. ### What we're looking for - 3+ years designing custom machinery, automation equipment, or robotic cells at a machine builder or integrator. - Strong component selection: pneumatics, linear guides, ballscrews, servo/stepper sizing. - Fast and practical; you can take a concept to a buildable design in days. - SolidWorks proficiency; good DFM/DFA habits. - Part feeding and CNC machine tending experience a plus. Compensation: $70,000–$100,000 per year, depending on experience.
