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.\nWe 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.\nRole & Responsibilities\nAs a Staff C++ Architecture Engineer, you will…\nDesign and implement high-quality C++ (and some Python tooling) for ROS/ROS 2 nodes, libraries, and utilities (rcl-cpp, actions/services, components, lifecycle, launch).\n\nIntegrate and support sensors and actuators (cameras, LiDAR, robot controllers); develop and maintain device drivers, message interfaces, health checks, and diagnostics.\n\nArchitect scalable, testable subsystems (configuration, state machines, fault recovery, observability) using robust design patterns.\n\nDiagnose and resolve performance and scalability challenges.\n\nOwn components, features, or systems with end-to-end responsibility.\n\nDevelop reusable software components for interfacing with back-end platforms.\n\nPartner with cross-functional teams (product, design, operations, infrastructure) to create innovative application experiences.\n\nContinuously improve code quality, efficiency, and performance.\n\nConduct reviews, write clear documentation, and advocate best practices for safety, reliability, and maintainability.\n\nExport Control Requirements\nIn order to comply with the export regulations of the United States Government, it is required that the applicant must fall under one of the following categories: (i) U.S. citizen or national, (ii) U.S. lawful permanent resident (i.e. current green card holder), (iii) Refugee under 8 U.S.C. § 1157, or (iv) Asylee under 8 U.S.C. § 1158.\nMinimum Qualifications\nBachelor’s degree in Computer Science, Robotics or equivalent practical experience.\n\n8+ years of industry experience in developing and shipping production software in modern C++ (14/17/20).\n\nProven track record of owning and delivering components, features, or systems.\n\nFamiliarity with large-scale system design and architecture best practices.\n\nExperience with concurrency and real-time programming.\n\nStrong analytical, problem-solving, and decision-making skills.\n\nStrong skills in debugging and troubleshooting real robots/embedded systems (logs, tracing, sanitizers, core dumps).\n\nExcellent communication and cross-team collaboration skills.\n\nAbility to thrive in a fast-paced environment with shifting priorities.\n\nPreferred Qualifications\nMaster’s or PhD in Computer Science or Robotics.\n\n3+ years of hands-on experience with ROS or ROS 2 (nodes, messages, actions/services, launch, packaging).\n\nExpertise in object-oriented design and API development; familiarity with SOLID principles and clean architecture.\n\nProficiency with Linux, CMake/colcon, Git, and common CI tools (e.g., GitHub Actions, GitLab CI).\n\nSolid foundation in algorithms and data structures.\n\nRecognized as a technical mentor or thought leader.\n\nGrayMatter Robotics provides equal employment opportunities to all employees and applicants for employment and prohibits discrimination and harassment of any type without regard to race, color, religion, age, sex, national origin, disability status, genetics, protected veteran status, sexual orientation, gender identity or expression, or any other characteristic protected by federal, state or local laws.
