About The Position

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.

• Familiarity with large language models, AI-assisted tooling, or agents as applied to bug triage or quality workflows
• Excellent written and verbal communication skills, with the ability to clearly summarize technical findings for a range of audiences
