Staff C++ Architecture Engineer

Summary GrayMatter Robotics is a well-capitalized Physical AI company headquartered in Los Angeles, building Factory SuperIntelligence (FSI) through systems that learn, adapt, and develop genuine process intelligence across every part they touch. Our robots take on the tedious, hazardous, and ergonomically demanding work that has kept manufacturing dependent on a shrinking skilled workforce, delivering superhuman performance. Robotics has a demo problem. GMR doesn't. Our systems are in active production today, adapting autonomously to real geometries, real materials, and real process variation without reprogramming. We deliver our system through a Robots-as-a-Service (RaaS) model that converts capital expenditure into an operating subscription, making Physical AI accessible to the manufacturers who need it most. We hire people who want to solve hard physical problems at an industrial scale. We help manufacturers improve the quality of life for their workforce while increasing production capacity, and reducing scrap, repair, and rework costs. As a Staff 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. Role & Responsibilities As a Staff C++ Architecture Engineer, you will… Design and implement high-quality C++ (and some Python tooling) for ROS/ROS 2 nodes, libraries, and utilities (rcl-cpp, actions/services, components, lifecycle, launch). Integrate and support sensors and actuators (cameras, LiDAR, robot controllers); develop and maintain device drivers, message interfaces, health checks, and diagnostics. Architect scalable, testable subsystems (configuration, state machines, fault recovery, observability) using robust design patterns. Diagnose and resolve performance and scalability challenges. Own components, features, or systems with end-to-end responsibility. Develop reusable software components for interfacing with back-end platforms. Partner with cross-functional teams (product, design, operations, infrastructure) to create innovative application experiences. Continuously improve code quality, efficiency, and performance. Conduct reviews, write clear documentation, and advocate best practices for safety, reliability, and maintainability.
