Health Technologies is a unique cross-functional organization at Apple that works on inventing, researching, and validating new physiological sensing methods for Apple's current and future hardware platforms and software portfolio. We have an opportunity for a highly capable Data Engineer to join our multidisciplinary Software Team. You will integrate with our research study leads, data scientists, and engineers to design and support effective data pipelines and analysis workflows. Additionally, you will build and maintain the iOS and macOS apps that collect data and prototype new health features. This is a rare blend of data engineering rigor and Apple-platform app development, in service of research years ahead of product launch cycles.
