Internship - Swift Compiler and Runtime Engineer

Internship - Swift Compiler and Runtime Engineer

Apple's Swift Compiler and Runtime teams are now looking for interns for 2025! We are looking for students who want hands-on experience working on these exciting technologies. We have interesting problems to solve at every level, from low-level assembly to high-level Swift code. No prior language, compiler, or debugger experience is required, and candidates without such experience are encouraged to apply. Candidates should be comfortable writing code in C++.

Description

As a part of this team, you will be helping to develop the Swift compiler and associated runtime. You will work alongside experienced compiler engineers to implement high-level language analysis, new performance optimizations, improved code generation, or finding new and better ways to test and verify the correctness of a complex and critical codebase. You’ll be working primarily in C++, and the majority of your work will go directly into our github.com/swiftlang repositories, where it will be visible to the entire world.

Minimum Qualifications

• Internships are restricted to students. Students must be enrolled in school in the quarter/semester immediately following the internship. We are looking for candidates of all education levels, from Bachelor’s to Ph.D. The position will be onsite in our London office.

Preferred Qualifications

• Swift, compiler, optimization, C++, runtime, performance, program analysis, open source
