Apple • Cupertino, CA

About The Position

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, software engineers on the Xcode team have the unique and rewarding
opportunity to apply personal experience to enhance and augment the tools they
use everyday. The Xcode team is looking for a detail-oriented and focused
Quality Engineer with deep curiosity about how complex systems fail — and the
initiative to find those failures before developers do. This position involves
not only ensuring that each of these features work but they also coalesce into a
cohesive development environment. Responsibilities include API/Integration
testing, manual/LiveOn testing, building test tools, developing automation
platforms, and working to continuously improve Xcode’s runtime tools - including
profiling, debugging and memory diagnostics.

DESCRIPTION

We're looking for a highly creative and self-motivated individual, excellent at
creating and maintaining tests/tools and communicating with the tools
development team about feature quality — while also engaging compiler, runtime,
and OS teams when issues cross those boundaries. You’ll be paired with a tools
development team, and work with them to extend their automated testing to help
ship a high quality Xcode and Instruments. You’ll have the opportunity to build
shared APIs for testing, and be challenged to come up with testing strategies
that maximize coverage of your component 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.
In this position, you will: Identify test scopes and develop quality plans for
complex, dependency-heavy features across rapid development cycles. Execute
tests with attention to detail and communicate the overall quality to
stakeholders. Drive teams to resolve issues, championing problems that degrade
the developer experience in profiling, debugging, or memory analysis workflows.

Requirements

• BS in Computer Science or equivalent experience
• Strong object-oriented programming experience in Swift and Objective-C, with Python or other scripting experience a plus
• Excellent troubleshooting skills with a passion for quality
• Experience in writing automation tests at API, UI, and non-UI levels
• Collaborative and curious contributor with a proactive communication and demonstrated ability to lead projects
• Ability to reason about how failures in dependent systems (OS, compiler, runtime) can surface in higher-level tools

Nice To Haves

• Experience with profiling, memory diagnostics, or other runtime analysis tools
• Proven experience designing test strategies that account for complex failure modes and cross-system dependencies
