Job description

We're looking for a highly creative and self-motivated individual who is excellent at creating and maintaining tests and tools, and communicating with the development team about feature quality — while also engaging compiler, runtime, and OS teams when issues cross those boundaries. You'll be paired with a Xcode feature team and work with them to extend their automated testing coverage to help ship a high-quality Xcode and Instruments. You'll have the opportunity to build shared APIs for testing and be challenged to develop testing strategies that maximize coverage with minimal manual intervention. This includes reasoning about failure modes that span OS, compiler, and runtime boundaries — where the root cause of a bug may live far from where it surfaces. BS in Computer Science or equivalent experience Strong object-oriented programming experience in Swift and/or Python or other scripting experience required Demonstrated experience writing and executing detailed test plans for complex software systems Proven ability to identify, reproduce, and clearly document software defects; strong troubleshooting and root-cause analysis skills Experience with UI framework testing, debugging, bug hunting, and regression identification Experience with macOS/iOS platform frameworks such as AppKit, UIKit, SwiftUI, XCTest, or LLDB Demonstrated use of LLMs or AI tooling to improve quality, failure triage, or automation workflows Track record of shipping test automation frameworks at scale; experience mentoring engineers or leading cross-team quality initiatives
