Job description

Lead C++ Architecture Engineer at GrayMatter Robotics

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.

Role & 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.

Minimum Qualifications

• Bachelor’s degree in Computer Science, Robotics or equivalent practical experience.
• 5+ 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 secure work authorization in the United States and maintain ongoing work authorization beginning at the time of hire through the entirety of employment.

Preferred Qualifications

• 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.
