About The Position

Headquartered in sunny Los Angeles, GrayMatter Robotics is a well-capitalized AI robotics startup serving the manufacturing industry. We empower shop floor workers with our smart robots that assist with tedious and ergonomically challenging tasks, specifically in automated surface finishing. Our proprietary GMR-AI™ software is integrated with state-of-the-art industrial robots, sensors, and tools to create application-specific turnkey solutions for customers through a Robot-as-a-Service (RaaS) model. We help manufacturers improve the quality of life for their workforce while increasing production capacity, and reducing scrap, repair, and rework costs. As a Lead C++ Architecture Engineer, you will join our Robotics Software Engineering Team onsite in our Carson, CA office to design and implement robust, scalable software architectures that power our advanced robotic systems. You will lead the development of core C++ and ROS/ROS 2 components, architect high-performance subsystems, and integrate cutting-edge hardware to deliver reliable, production-ready automation solutions.
