StaffMechatronicsEngineer

Summary GrayMatter Robotics is a well-capitalized Physical AI company headquartered in Los Angeles, building toward Factory SuperIntelligence (FSI), where intelligent machines learn, adapt, and improve the way factories run. Our robots take on the tedious, hazardous, and ergonomically demanding work that has kept manufacturing dependent on a shrinking skilled workforce. Delivered through a Robots-as-a-Service (RaaS) model, our systems improve with every part they touch, learning from one of the largest real-world manufacturing datasets ever assembled. We work at the intersection of AI, robotics, and manufacturing, and we hire people who want to solve hard physical problems at industrial scale. GrayMatter Robotics is seeking a Staff Mechatronics Engineer to lead the design, development, and deployment of advanced robotic systems for manufacturing automation. This role is intended for a senior technical leader who operates with high autonomy, influences system architecture, and mentors engineers while remaining hands-on. Strong controls and mechatronics foundation with hands-on experience in PID tuning, motor and drive control, and frequency response analysis, combined with practical debugging using lab instruments and PLC-based industrial automation hardware (PLCs, safety modules, sensors, actuators). Proficient in embedded C/C++ and Python for low-level control and integration, and experienced in full-system robotic design spanning electrical, mechanical, and controls domains. Designs and sources components, creates CAD and technical drawings, and rapidly prototypes using 3D printing and basic shop tools with a strong DFM mindset. Applies working knowledge of power electronics and common hardware certification standards, and leads thorough testing, validation, and troubleshooting of automation systems before deployment. Collaborates cross-functionally to translate customer needs into buildable solutions, standardizes PLC architectures within robotic cells, drives co
