About The Position

The people here at Apple don't just build products - they build the kind of wonder that's revolutionized entire industries. It's the diversity of those people and their ideas that encourages the innovation that runs through everything we do, from amazing technology to industry-leading environmental efforts. Join Apple, and help us leave the world better than we found it. Do you have a passion for invention and self-challenge? Do you thrive on pushing the limits of what’s considered feasible? As part of our Battery Engineering group, you’ll help craft creative battery solutions that deliver more energy in smaller spaces than ever before. You’ll work across disciplines to transform improved hardware elements into a single, integrated design. Join us, and you’ll help us innovate new battery technologies that continually outperform the previous iterations. By collaborating with other product development groups across Apple, you’ll push the industry boundaries of what batteries can do and improve the product experience for our customers across the world. The Battery Product Development team at Apple produces high energy and highly reliable embedded battery systems for all product teams. Tightly integrated with Product Development, Operations, Industrial Design and Reliability Testing groups, we own battery module development from initial system architecture through ramp. The Battery Cell Engineering Team works within the Battery Product Development organization and is seeking a cell engineer focused on developing and qualifying advanced lithium based rechargeable cell designs for new product consideration, develop performance and test specifications for batteries for new products, work to define cell designs that meet internal customer requirements and supervise failure analysis and root cause investigations.

Requirements
