Remanufacturing Engineer II, High Voltage Battery

About Rivian

Rivianis 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.

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‑diving 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.
• Provide on‑site engineering support for High Voltage Battery assemblies and components in Shepherdsville, Kentucky, covering series production and legacy products.
• Actively support the development and validation of remanufacturing processes
• Perform technical analyses, document issues, prioritize and elevate to the appropriate assignee
• Accurately and clearly communicate detailed steps taken to verify issues
• Collaborate with the Reman team onsite in Kentucky along with Manufacturing, Process, and Quality teams to resolve issues related to failed High Voltage Battery assemblies and components.
• Assemble, maintain, and/or modify test equipment and data acquisition systems as needed
• Responsible for continuous improvement in the remanufacturing process by creating new tooling, fixture and eliminating production bottlenecks
• Comfortable working in a small‑team environment where individuals are expected to fill the needs of multiple roles to ensure program success
• May perform other duties as assigned

• BS+ in engineering and 1-3+ years working with mechanical/electrical systems, hand tools, and test equipment in a manufacturing or prototype lab environment
• Excellent problem‑solving skills with a focus on core engineering principles
• Passion for working on products that involve the intersection of mechanical, electrical, and software engineering
• Dedicated to expanding knowledge of electro‑mechanical systems by leveraging a passion for diagnostic testing and teardowns to identify and resolve root‑cause failures
• Previous experience in engineering design tools Catia, Solidworks, Autocad or similar
• Self starter, must be willing to run to and seek out issues
• Experience with issue tracking and collaboration tools (Jira, Trello, Gitlab, Asana, Confluence, etc.)
• Ability to view, read, and interpret mechanical & electrical drawings
• Experience with MS Office and Atlassian (Confluence and Jira) software
• Knowledge of Battery cyclers and hardware (NHR, NI, EA)
• Knowledge of CAN/Ethernet tools for debugging purposes
• Knowledge of CANalyzer, CANape, Labview or other diagnostics software
• Knowledge of Python and/or C++ for interfacing with measurement hardware
• Knowledge of high…
