Staff Software Engineer, ASE Storage Infrastructure

Apple Services Engineering (ASE) designs, builds, and operates the cloud infrastructure, server systems, and platform technologies that power many of Apple's most beloved experiences. Within ASE, the Storage Platforms organization develops the systems that store, protect, and serve Apple's data at massive scale, with a mission to deliver storage that is durable, secure, highly available, and operated with excellence. Engineers on this team will have the rare opportunity to work on storage device-optimized low-level storage, large-scale distributed systems, and high-performance IO stacks operating at mission-critical levels of availability and durability. Apple Object Storage is a massive scale storage system that provides the foundation for storing unstructured object data across Apple. The Apple Key-Value Store provides the metadata storage to make that happen, as well as supports other distributed Key-Value workloads within Apple Cloud platform. We are looking for a passionate lead engineer/architect with experience in developing large-scale services and infrastructure to take a central role in designing and building our next version. Join our friendly, collaborative, highly-motivated team!
