Battery Engineer - Cell Development

The Battery Engineer / Senior Battery Engineer will join the product development team to drive cell-level development of next-generation electrolytes into larger formats. In this role, you will drive cell design, electrolyte optimization, and formation protocol development for lithium-ion chemistries, with a strong emphasis on cylindrical cell development. You will work cross-functionally with electrolyte and manufacturing teams to translate lab-scale results into pilot-scale cells and will play a central role in diagnosing performance and safety issues through postmortem failure analysis and electrochemical characterization. Key Responsibilities Evaluate cell designs and electrolyte optimization for high-voltage lithium-ion chemistries from pouch format into cylindrical and prismatic cell formats. Develop and refine cell formation protocols to improve performance and manufacturing yield. Conduct postmortem failure analysis and electrochemical characterization to diagnose degradation mechanisms and drive corrective action. Drive cell development and process optimization in pilot-scale manufacturing, including assembly, testing, and troubleshooting of cylindrical and prismatic cells. Perform data analysis of cell life and electrolyte performance under diverse testing conditions (e.g., fast charge, high voltage, low/high temperatures, etc) across multiple cell chemistries and formats. Deliver technical reports to multidisciplinary R&D teams, summarizing test results, data analysis, and recommendations to guide project decisions. Champion safe lab operations, ensuring adherence to safety protocols across all laboratory and pilot-scale testing activities. Qualifications Bachelor's degree in engineering, materials science, chemistry, or a related field (advanced degree a plus). Experience in lithium-ion cell development, including cell formation protocol development, postmortem failure analysis, and electrochemical characterization. Hands-on experience with cell development in pilot-scale manufacturing environments, from prototype build through process optimization. Experience with cylindrical and/or prismatic cell formats is required Strong laboratory skills, including precise instrumentation handling, data collection, and experimental design, along with a demonstrated commitment to safe lab operations. Bonus Skills Familiarity with Neware and Arbin battery cyclers and associated software for electrochemical testing and analysis. Prior experience with cell design and scale-up efforts spanning multiple form factors, including transition from pouch to cylindrical and prismatic cells. Cross-functional project execution experience, working alongside materials, manufacturing, and product teams to bring cells from lab to pilot scale. #J-18808-Ljbffr Mapt
