Supply Chain Manager

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 Supply Chain Manager, you will join our team onsite in our Carson, CA office to develop and execute procurement processes, source suppliers and manage vendor relationships to ensure a seamless supply chain while optimizing costs. You will also collaborate with cross-functional teams, make strategic decisions and implement best practices within our procurement function. Role & Responsibilities Own end-to-end procurement operations: source and negotiate with suppliers, issue purchase orders, and confirm correct, on-time fulfillment in partnership with the logistics and deployment teams. Build and implement procurement systems and tools that give GMR clear visibility into every open PO, vendor commitment, and lead time as deployment volume grows. Negotiate supplier contracts and resolve delivery defaults against fixed lead-time commitments, treating vendor recovery as a core part of the job rather than an exception. Evaluate, select, and onboard suppliers against cost, quality, and engineering requirements, then manage the relationship through regular performance reviews. Partner directly with engineering and product teams to translate their requirements, including ones outside your prior experience, into concrete sourcing and purchasing plans. Analyze demand forecasts tied to robot deployment volume, including mobile robot rollouts, to determine what GMR needs, what it is missing, and what it will need next. Act as the working bridge between vendors and quality, driving down rework and turnaround time on parts and components that fall short of spec. Use AI-enabled procurement and data tools to automate reporting, flag anomalies in spend or lead time, and speed up sourcing research. Develop and report procurement metrics, cost savings, and sourcing effectiveness to the Head of Operations.
