We are seeking a highly motivated Battery Hardware Engineer to develop and optimize battery pack and cell designs for next-generation energy storage applications. The role requires strong technical knowledge of electrochemical systems, mechanical and thermal design, and experience with battery system integration in Consumer Electronics applications such as laptop, battery pack, tablet or phones.In addition to core design responsibilities, this role requires active involvement in factory build support, including solving during prototype and mass production builds, developing and implementing factory-level testing solutions, and ensuring product reliability and quality. The engineer will lead or support Failure Analysis and Corrective Action (FACA) processes, respond to line-down events, and drive root cause analysis and rapid issue resolution in coordination with manufacturing, quality, and supplier teams. This position is critical in bridging the gap between design intent and scalable, high-quality production.
