Software Integrity Engineer, Cocoa

Cupertino, California, United States Software and Services

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‑dived 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, watch

OS, and vision
