Imagine what we could create together! At Apple, new ideas have a way of becoming phenomenal products, services, and customer experiences very quickly. Bring passion and dedication to your job, and there’s no limit to what we could accomplish. Apple is seeking an experienced Senior iOS Software Engineer to contribute to the development of the next generation of cloud services infrastructure.

You will be responsible for designing and implementing key components of the iCloud platform, integrating novel fundamental capabilities deeply into the core of Apple’s operating systems.

Your work will enable the creation of entirely new applications and the scaling of existing ones, including Face Time, Push Notifications, iCloud Drive, Photos, and Backup. This is an opportunity to make a significant impact. You will collaborate with highly skilled teams dedicated to engineering excellence and deliver features that uphold strong privacy guarantees for end users.

On the client-side of iCloud services, our team is responsible for establishing the foundations of a secure and private cloud.

This position requires close collaboration with the Cloud Kit team, as well as with several other teams working on server components and Apple’s Cryptography and Privacy teams.

The role entails both low-level (C/Objective C, lib dispatch, POSIX APIs) and system-level skills (synchronization protocols, framework design, IPCs, multi-process performance work, system-wide resource sharing). Reliability is paramount, and we seek engineers with a genuine passion for constructing complex systems that can seamlessly recover from errors.

• Work with adopters to craft clear APIs
• Work with the network and file system stacks to build performant system daemons
• Work with our server counterparts 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 Swift and/or Objective-C
• Experience building on Apple Platforms (macOS, iOS, watchOS, tvOS, etc.)
• Experience working with and building system-level frameworks and APIs
• Experience working with client-server architectures and network protocols in a distributed system
• Proven track record of working on rapid development cycles and shipping software on tight schedules
• Bachelor's degree, or above, in an engineering-related field or equivalent related experience

• Experience with Swift concurrency
• Experience with security, privacy, and cryptography concepts
• Experience with event-based programming and/or inter-process communication is a plus
• Ability to build relationships in highly cross‑functional environments
