Job description

The Xcode and Developer Tooling teams provide the tools to develop software for Apple's innovative iOS, watchOS, tvOS and macOS platforms. Because tools are our products, we have the unique and rewarding opportunity to apply personal experience to enhance and augment the tools we and agents use everyday. Xcode Previews and Playgrounds change the way we build apps with immediate feedback for both developers and agents, whether in powerful IDEs like Xcode or in external experiences via Xcode's rich suite of MCP tools. The Live Coding team is looking for an engineer who loves to learn to help us take fast, iterative development even further.

Description

We’re looking for an engineer who loves to sit at the cross section of languages, compilers, frameworks like SwiftUI and FoundationModels, operating systems, and user interface development. Xcode Previews touch every part of the system: from the details of the Swift grammar, to build systems, to app development and lifecycle, to the forefront of agentic techniques, to the depths of our operating systems. Working on this team can involve everything from low level programming to high level UI design and interaction to agentic workflows and strategies. We develop components that are built in to all of our operating systems, as well as technology and experiences used by Xcode and other developer tools that uses those operating system components to bring the developer's code to life. This position requires a highly creative, curious, and self-motivated individual. We're looking for engineers who love to learn, love to work with a variety of teams and disciplines to bring the best experience for our developers and agents, and who thrive on ambiguous problems to explore unpaved paths. You will have the opportunity to affect design decisions not only on developer-facing tools, but also for our frameworks, and for future products across the Apple ecosystem.
