The Cocoa team designs and implements frameworks which deliver user level features and developer APIs that are essential building blocks used by Apple and Apple's customers to create top-notch applications for the Apple platforms. The team's deliverables include a wide range of rich functionality in areas such as user interface, text, graphics, document handling, asset management, data modeling, persistence, concurrency, and operating system interaction. We are looking for critical thinkers with a sharp eye for detail who would like to play a key role in qualifying the Cocoa frameworks and helping ensure Apple software is of the highest quality. As a Software Development Engineer in Test (SDET), you will partner closely with engineering teams to design robust testing strategies, develop automated tests, and build scalable test infrastructure. This role blends quality assurance with software development, placing a strong emphasis on improving overall product quality through thoughtful automation. You will gain deep domain knowledge and use it to shape effective test strategies, while architecting, prototyping, and maintaining test applications and automated suites that validate SDKs, APIs, and critical Cocoa framework functionalities. Your keen debugging skills and attention to detail will be essential in surfacing actionable defects and elevating the reliability of our systems. We cultivate a culture rooted in curiosity, initiative, and continuous learning, especially as we navigate new technologies and evolving features. If you're ready to shape the future of testing and be a catalyst for innovation, then join our team.
