Apple is where individual imaginations gather together, committing to the values that lead to great work. Every new product we build, service we create, or Apple Store experience we deliver is the result of us making each other’s ideas stronger. That happens because every one of us shares a belief that we can make something wonderful and share it with the world, changing lives for the better. It’s the diversity of our people and their thinking that inspires the innovation that runs through everything we do. When we bring everybody in, we can do the best work of our lives. Here, you’ll do more than join something — you’ll add something. Do you love working on challenges that no one has solved yet? Do you like changing the game? Envision what you could do here. At Apple, we believe new ideas have a way of becoming extraordinary products, services, and customer experiences very quickly. Bring passion and dedication to your job and there's no telling what you could accomplish. This position contributes to the development and qualification of advanced lithium ion battery technology for portable power consumer applications. You will work with internal multi-functional teams to develop battery firmware, algorithm and battery management system (BMS) qualification protocols using system requirements, user profiles and the battery health monitoring estimation models to ensure high level of customer experience. You will collaborate with BMS firmware and algorithm engineers to improve the quality, productivity, and efficiency of Apple products.
