This is the story of Royer Ramirez Ruiz, the engineer who built the infrastructure that made Rivian's rapid electric vehicle production possible. When Rivian's first R1T pickup truck rolled off the line in September 2021, the company faced an enormous challenge: moving from a few prototypes to mass production. By 2024, Rivian had built more than 100,000 vehicles, becoming one of only two U.S. automakers producing electric vehicles at that scale. Among the engineers who helped make that possible was Ramirez Ruiz. He joined Rivian at a pivotal moment, as the company transitioned from an ambitious startup to a full-scale manufacturer. Starting as a Senior DevOps Engineer, Royer built the foundations that connected software, networking, and factory operations, laying the groundwork for Rivian's growth from fewer than 600 vehicles to over 100,000 across the R1T, R1S, and EDV models. Today, as a Staff Engineer at Maven Robotics, he continues to design large-scale AI and robotics infrastructure systems that bridge the gap between data science and real-world automation. The Challenge of Smart Factory Data "When you're building the factory of tomorrow, the infrastructure has to be bulletproof," Ramirez Ruiz recalls. "We weren't just building cars. We were building the backbone that let every team, from quality to supply chain to operations, make real-time decisions." At Rivian's massive 2.6-million-square-foot plant in Normal, Illinois, every robot, stamping press, and battery line produced mountains of data. Ramirez Ruiz built systems to capture and analyze that information in real time, replacing manual checks with continuous monitoring. This shift was critical to hitting Rivian's ambitious goals, including Amazon's order for 100,000 electric delivery vans. Bringing AI to the Battery Line One of his most important contributions was applying edge AI to battery production. He led the deployment of AI models on the factory floor to validate laser welds on battery submodules. "The battery is the heart of every EV," he says. "A defect in welding can compromise safety. We needed real-time validation to catch issues before they reached the road." By running AI directly at the line, Rivian gained instant feedback without the lag of cloud-based systems. The result was safer, higher-quality batteries that could be built at scale. What was once experimental is now becoming standard practice across the industry. Scaling New Drive-Unit Assembly Lines When Rivian introduced its Enduro drive units, a new generation of efficient quad motors, the company needed infrastructure that could keep pace. Ramirez Ruiz worked with teams across the factory to make sure production systems were ready. "Scaling manufacturing isn't just about making more parts faster," he explains. "It's about building systems that adapt and improve as production grows." His work supported the rollout of these lines, which were vital for Rivian to meet demand for both consumer vehicles and Amazon's commercial fleet. Recognition Beyond Rivian In 2023, Ramirez Ruiz shared what he had learned with a wider audience. At KubeCon + CloudNativeCon, he spoke about operating production databases for smart factories at scale, addressing engineers and industrial leaders from around the world. "The automotive industry was watching Rivian closely," he reflects. "We showed that American companies could scale EV manufacturing, and the infrastructure patterns we developed became examples others could follow." As Rivian emerged as a major EV competitor, other manufacturers took note. Engineers from multiple companies reached out to learn from Rivian's infrastructure decisions, many of which traced back to systems Ramirez Ruiz had helped design. From EVs to Autonomous Robots By April 2024, Rivian celebrated its 100,000th vehicle, less than four years after the first R1T hit the road. Ramirez Ruiz has since taken that experience to Maven Robotics, where he now works as a Staff Engineer designing infrastructure for general-purpose autonomous robots. "Everything I learned at Rivian applies to robotics," he says. "Whether it's cars or robots, you need infrastructure that can handle real-time data, support AI, and grow with demand." Building for the Future Rivian is expanding again, breaking ground on a $5 billion facility in Georgia that will produce up to 400,000 vehicles annually. The foundations Ramirez Ruiz helped lay in Illinois still guide the company's growth. "The systems we built weren't just for the vehicles of that moment. They were platforms designed to scale for whatever came next," he says. His journey from supporting hundreds of vehicles to enabling more than 100,000 shows how infrastructure engineering can shape the future of manufacturing. As the EV revolution accelerates, the work he helped pioneer at Rivian continues to set the standard for American innovation.
