People at Apple don’t just build products — they craft the kind of experience that have revolutionized entire industries. The diverse collection of our people and their ideas inspire innovation in everything we do. Imagine what you could do here! Join Apple, and help us leave the world better than we found it. The Apple Service Engineering (ASE) team builds and provides systems and infrastructure that fuel Apple’s services (such as iCloud, Apple Music, Apple Fitness, and Apple TV). We are the foundation on which Apple’s software developers build the products that our customers love. Our services have to scale globally, stay highly available, and "just work.” We are looking for a passionate and dedicated Senior Software Engineer who will focus on creating fundamental security services, addressing identity and authorization challenges on a large scale within the ASE organization. Success in this role requires individuals to possess a blend of profound technical expertise, extensive knowledge in security, and substantial experience in large-scale operations.
