# Software Development Engineer - System Analytics & Intelligence (SAIL)

Core OS ships the foundational software that powers every Apple product.

You'll engineer a unified platform that correlates events across many specialized systems to provide end-to-end observability of the Core OS development workflow. We're looking for engineers who put the customer experience first, are passionate about building scalable and reliable services, and bring strong data engineering foundations. This role goes further than building and ru
