Swift Compiler Engineer

Cupertino, California, United States Software and Services

The Swift Compiler Team at Apple is a unique opportunity to evolve the Swift programming language and related developer tools that shape the experience of writing Swift code. We are looking for a software engineer passionate about programming languages and developer experience. We are a fast paced and collaborative group working to improve and expand the Swift language and the compiler technology that provides Swift language support to IDEs and editors.

You will have experience with some of the skills below. Nobody is expected to have experience with all of these, but we are looking for someone with a strong desire to learn what you don’t know.

The Swift Compiler Team is looking for an engineer to collaboratively design and implement new language features, improve type checking performance, and enhance the Swift developer experience through diagnostics and other compiler-driven tools. Drawing from your own experience writing code, internalizing a programming model, and working with developer tools, you will bring diverse perspectives and a desire to help solve the problems you’ve encountered in your own development work.

This position requires a highly creative and self‑motivated individual, capable of communicating with and giving feedback to others in a range of roles across software engineering at Apple, the open source Swift community, and beyond. You will have the opportunity to affect design decisions not only on the Swift programming language and its developer‑facing tools, but also general programming patterns, applications of Swift, and community building/outreach across the Swift ecosystem.

Iteration and innovation are key to this role. You should relish change, and be prepared to question commonly established practices, with the desire to create the best possible experience to enrich the lives of programmers, both current and future. As a Swift compiler engineer, you will:

• Collaborate with teammates through in‑person conversations, pull requests, and other online discussions.
• Collaborate with open source contributors through pull requests and the Swift Forums.
• Design and implement new language features and tooling improvements, documenting and iterating on your design decisions through the Swift evolution process.
• Welcome constructive feedback on your changes from Swift programmers, and iteratively improve the experience of writing Swift.
• Drive the testing, integration, and adoption of your changes into the development ecosystem.

• Demonstrated ability to communicate through technical writing.
• Curiosity for understanding a programming mental model and how code works “under the hood”.
• Experience with software design and programming in a statically‑typed language such as (but not limited to) C++ or Swift.
• Familiarity with algorithms and data structures.
• Ability and motivation to investigate and learn what you don’t know.
• Receptiveness to constructive feedback and mentorship.

• Swift development experience is a plus, but not required.
• Prior experience working on compilers or developer tools is a plus, but not required.
