Data Analytics Engineer

Cupertino, California, United States Software and Services

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.The Applied Health & Sensing team builds the pipelines and infrastructure that turn raw motion data from Apple devices into insights that help users improve their health. Every time someone exercises or moves with their device, engineers and scientists on this team are behind the systems that capture, validate, and make sense of that data at scale. As a member of our dynamic group, you'll build and monitor the data pipelines that power our products, run large-scale analyses that uncover how people actually use and benefit from them, and help shape upcoming products that delight and inspire millions of Apple customers every day. Join our team and enrich lives by shipping software and data systems that motivate fitness goals, improve health, and enhance the way customers interact with our products.
