Quality & Test Automation Engineer – Xcode

Summary

The Xcode team provides the tools to develop software for Apple's innovative iOS, macOS, watchOS, tvOS, and visionOS platforms. Because tools are our products, engineers on the Xcode team have the unique and rewarding opportunity to apply personal experience to enhance and augment the tools they use every day!

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.

Preferred Qualifications

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

Minimum Qualifications

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
