Posted on Jan 28, 2026
Apple is seeking an experienced Software Engineer to help build the next generation of cloud services infrastructure. You'll design and implement key components of the iCloud platform, integrating powerful new capabilities deep into the core of Apple's operating systems. Your work will enable entirely new applications and help scale existing ones—including iCloud Drive, Photos, Notes, FaceTime, and many more. This is an opportunity to make a significant impact. You'll collaborate with highly skilled teams dedicated to engineering excellence and deliver features that uphold strong privacy guarantees for our users.
Our team builds the on-device software that makes iCloud work. In this role, you'll focus on two major areas: * Private Cloud Compute — Apple's platform for running workloads with enforceable privacy and security guarantees. This system powers many Apple Intelligence and iCloud features. * CloudKit — Our privacy-focused sync and storage system. CloudKit manages user data for most Apple apps, as well as many third-party apps. You'll design and build the frameworks and daemons that support both systems, working closely with engineering teams across the company who are adopting this technology—and with colleagues who build our client and server dependencies. A strong candidate will have experience and interest in Apple platforms, ready to tackle challenges like protocol design, interprocess communication, device resource management, API design, reliability, and performance. Since so much of the user experience depends on services, we're also looking for engineers who are passionate about complex distributed systems. We value thoughtful engineering, collaborative problem-solving, and shipping work we're proud of. You'll have opportunities to deepen your expertise in distributed systems, security, and platform engineering.
- Collaborate with adopters to design clear, intuitive APIs
- Build daemons and components that make use of system resources efficiently
- Partner with server teams to design scalable features and protocols
- Implement core components of the cryptographic protection of cloud data
- 5+ years of software engineering experience with strong programming skills in Objective-C and/or Swift
- Experience building on Apple Platforms (macOS, iOS, watchOS, tvOS, etc.)
- Experience in building system-level frameworks and APIs
- Experience with Swift concurrency
- Strong communication skills
- Familiarity with event-based programming or inter-process communication is a plus
- Track record of shipping software on rapid development cycles
- Bachelor's degree in an engineering-related field or equivalent related experience
