Staff C++ Architecture Engineer

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. 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. 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.

Responsibilities

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

Requirements

Bachelor’s degree in Computer Science, Robotics or equivalent practical experience; 8+ years of industry experience in developing and shipping production software in modern C++ (14/17/20); Proven track record of owning and delivering components, features, or systems; Familiarity with large-scale system design and architecture best practices; Experience with concurrency and real-time programming; Strong analytical, problem-solving, and decision-making skills; Excellent communication and cross-team collaboration skills; Ability to thrive in a fast-paced environment with shifting priorities; Must be a U.S. citizen or national, U.S. lawful permanent resident (green card holder), refugee under 8 U.S.C. § 1157, or asylee under 8 U.S.C. § 1158 (export control requirement)

Nice to have

Master’s or PhD in Computer Science or Robotics; 3+ years of hands-on experience with ROS or ROS 2 (nodes, messages, actions/services, launch, packaging); Strong skills in debugging and troubleshooting real robots/embedded systems (logs, tracing, sanitizers, core dumps); Expertise in object-oriented design and API development; familiarity with SOLID principles and clean architecture; Proficiency with Linux, CMake/colcon, Git, and common CI tools (e.g., GitHub Actions, GitLab CI); Solid foundation in algorithms and data structures; Recognized as a technical mentor or thought leader

Benefits

Bonus or commission; Equity; Medical; Dental; Vision; Unlimited PTO; 401(k) plan + employer match; Regular offsite events; Discretionary fund for enhancing productivity
