Senior Software Engineer

Our Swift Server Networking team is responsible for building libraries and frameworks which form the foundations of mission-critical systems at Apple. We write software in the Swift programming language and specialise in frameworks for distributed systems. Much of the software we produce is published as open source (such as SwiftNIO and gRPC Swift), as we firmly believe in growing a strong community. This, combined with our drive to create amazing products, makes the team a truly exciting place to work.

We’re a collection of highly skilled and friendly engineers who value each other’s opinions and experience. We strive for excellence and believe strongly in the quality of our output. We have built a team of domain experts who specialise in specific core subject areas, and also have broad experience of cloud software services and platforms.

You will have significant responsibilities in building and improving libraries and SDKs for running large-scale, mission-critical services in Swift. You will have the chance to influence the direction of the platform and collaborate with multi-functional teams across Apple to help define, implement, and deliver functionality to help build the next generation of Apple Services.

Our work takes us across multiple domains, from cloud services to iOS and macOS SDK development. The common thread for all of our development is a focus on the Swift programming language. If you have experience in any of these areas, you can hit the ground running, but we believe that great engineers can learn these skills on the job.

Successful candidates will have strong engineering skills and communication, as well as the ability to build relationships and collaborate across the company. You will have a real passion for quality, technical excellence, and an ability to understand complex systems. If this sounds like you, then we would love to hear from you.
