Do you have a sharp eye for detail, a love of problem-solving, and a passion for software quality? Join the Cocoa QA team to help raise the bar for the frameworks that power every Apple experience. Our team sits at a unique intersection: we are engineers who think like detectives, using deep platform knowledge, automation, and analytical rigor to triage, investigate, and resolve the bugs that matter most across Cocoa. Whether we're routing a newly filed radar to exactly the right engineer, bisecting commits to pinpoint the precise change that introduced a regression, or building tools that make the whole process faster and smarter, our work has a direct and measurable impact on the quality of software that ships to the world. If you're technically sharp, genuinely curious, and motivated by the satisfaction of turning chaos into clarity, we'd love to meet you.
As a Software Integrity Engineer on the Cocoa QA - Integrity team, you will triage and investigate incoming bug reports across Cocoa components, routing issues to the right engineering teams and conducting deep-dive investigations - including commit bisection - to accelerate the fix lifecycle. You will also contribute to presubmission testing, write automation and tooling using Xcode, XCTest, and Swift, and support new feature work, ensuring that Cocoa frameworks meet Apple's high bar for quality across macOS, iOS, watchOS, and visionOS.
Triage and screen incoming Radar bug reports across Cocoa components, accurately routing issues to the appropriate developer or sub-component.
Conduct in-depth investigations into escalated bugs - tracing regressions to their source and providing engineers with clear, actionable findings that accelerate fixes.
Develop and maintain automation tools, test harnesses, and utilities using Swift, XCTest, and Xcode to scale and improve the screening process.
Contribute to presubmission testing efforts, verifying that changes to Cocoa frameworks meet quality standards before integration.
Identify trends in incoming bug reports and surface insights that help engineering teams prioritize and allocate resources effectively.
Collaborate with Cocoa framework engineers, QA partners, and cross-functional teams to continuously improve bug triage processes and tooling.
Assist in new feature work and quality initiatives as team needs evolve, demonstrating versatility across the breadth of Cocoa QA responsibilities.
