About RivianRivian is on a mission to keep the world adventurous forever. This goes for the emissions-free Electric Adventure Vehicles we build, and the curious, courageous souls we seek to attract.
As a company, we constantly challenge what's possible, never simply accepting what has always been done. We reframe old problems, seek new solutions and operate comfortably in areas that are unknown. Our backgrounds are diverse, but our team shares a love of the outdoors and a desire to protect it for future generations.
Role SummaryThe Factory Design & Simulation team is at the core of Rivian's mission to redefine the future of automotive manufacturing. By turning industrial strategy into optimized value streams we enable production of market-leading EVs at scale. As part of Digital Manufacturing Engineering & Automation we create standardized tools and processes for throughput and material flow simulations. By understanding high-level factory goals and collaborating with teams designing individual systems, our team ensures the holistic factory design meets Rivian's ambitious objectives.
In this highly collaborative role, you will use discrete event simulation (DES) to guide factory design from early concepts to full operation. Partnering with industrial strategy, vertical, and integration teams, you'll define throughput architecture, establish buffer requirements, and create DES standards to ensure system designs achieve required production rates. Your responsibilities extend from executing simulations throughout the design process to identifying bottlenecks during production ramp-up and validation against actual production.
This position requires a comprehensive grasp of Manufacturing Engineering principles, complemented by a strong proficiency in simulation modeling. We seek candidates who solve complex problems using a first-principles approach and possess an intrinsic drive for design optimization. The successful candidate will thrive in a fast-paced environment, contributing to an agile, highly motivated team. You should be meticulous, analytical, and collaborative, with the ability to think at a systems level about ambiguous challenges and apply logical reasoning to build models that guide optimal factory design outcomes.
