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 fields 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.
As part of the materials characterization team, you will function as the subject matter expert for structural characterization and chemical analysis of lithium-ion battery materials and systems, with a strong foundation in Raman spectroscopy and complementary techniques including SEM, FIB-SEM, and FTIR. You will develop methods based on project needs to build a deep understanding of failure mechanisms and root causes in lithium-ion batteries, while also reviewing data from other analysts and coordinating the use of multiple techniques to drive materials understanding and causations between materials properties and performance.
