Remanufacturing Engineer, HV Battery

About Rivian

Rivian is on a mission to keep the world adventurous forever. The company builds emissions‑free electric adventure vehicles and is looking for curious, courageous souls who love the outdoors and want 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 life cycle of the High Voltage (HV) Battery—the most critical component of the Rivian platform—blending technical expertise with a “first principles” approach to ensure remanufactured products meet the highest standards of performance and sustainability.

• Engineering Oversight:
  Own the components and assemblies for HV battery packs, focusing on the transition from failed field units to certified remanufactured assets.
• Root Cause & Resolution:
  Lead deep‑dive investigations into electro‑mechanical failures, identify functional issues impacting production, and implement engineering solutions.
• Continuous Improvement:
  Drive 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, translating 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.
• On‑site Engineering Support:
  Provide engineering support for HV battery assemblies and components at Shepherdsville, Kentucky, covering series production and legacy products.
• Process Development:
  Actively support the development and validation of remanufacturing processes. Perform technical analyses, document issues, prioritize, and communicate steps taken to verify issues.
• Collaboration:
  
  Work with the Reman team onsite in Kentucky along with Manufacturing, Process, and Quality teams to resolve issues related to failed HV battery assemblies and components.
• Test Equipment:
  Assemble, maintain, and modify test equipment and data acquisition systems as needed.
• Tooling & Fixture Creation:
  Create new tooling and fixtures to eliminate production bottlenecks and continuously improve the remanufacturing process.
• Team Flexibility:
  Work effectively in a small‑team environment where individuals fill multiple roles to ensure program success. 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 products at the intersection of mechanical, electrical, and software engineering.
• Dedicated to expanding knowledge of electro‑mechanical systems through diagnostic testing and teardowns to identify and resolve root‑cause failures.
• Experience with engineering design tools (Catia, Solidworks, Autocad, or similar).
• Self‑starter, 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) and CAN/Ethernet tools for debugging.
• Knowledge of CANalyzer, CANape, Labview or other diagnostics software.
• Knowledge of Python and/or C++ for interfacing with measurement hardware.
• Knowledge of high‑voltage batteries, BMS, chargers and DC/DC AC/DC converters.
• Knowledge of automated DC‑powered tools, functions, programming and usage.
• Knowledge of Manufacturing Execution Systems (MES).
• Ability to stand for 8‑10 hours per day.
• Ability to lift 35 lbs.
• Occasionally required to climb, walk, kneel, or crouch.
• Possibly required to travel, less than 10% of time.
• Required to communicate by phone and/or e‑mail.
• Ability to perform all duties in an office environment that may contain ambient noise and temperature fluctuations.
