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.

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.
