Remanufacturing Engineer II, HV Battery

About Rivian Rivian 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 Summary The Battery Remanufacturing Team is seeking a hands-on Mechanical or Electrical Engineer to join the front lines of electric vehicle innovation. In this role, you will be a key driver in the lifecycle of the High Voltage (HV) Battery—the most critical component of the Rivian platform. As a Remanufacturing Engineer II, you will blend technical expertise with a "first principles" approach to ensure our remanufactured products meet the highest standards of performance and sustainability. Responsibilities Engineering Oversight: Own the components and assemblies for HV battery packs, specifically focusing on the transition from failed field units to certified remanufactured assets. Root Cause & Resolution: Lead deep-dive investigations into electro-mechanical failures. You will identify functional issues impacting production and implement engineering solutions to resolve them. Continuous Improvement: Leverage your previous experience to lead projects that improve battery yield, reduce waste, and optimize assembly processes. Cross-Functional Bridge: Serve as the technical link between Process/Test Engineering and Technical Operations. You will translate complex engineering requirements into actionable procedures for the production floor. Supplier & Lifecycle Management: Manage suppliers for rapid change implementation and provide a critical feedback loop to Product Development teams to prevent issue recurrence in future vehicle generations.
