Description

Apple's Compositing, Color, and Display Software organization provides the graphics software foundation for all of Apple's innovative products, including iPhone, iPad, Apple TV, Mac, Apple Watch and Vision Pro. Our goal is to enable developers and UI designers to create exceptional visual experiences by efficiently utilizing hardware acceleration and color technologies through compositing and display. We're a highly technical team working on critical compositing and windowing system components across Apple's platforms. Our mission is to maintain and evolve the compositing infrastructure that powers billions of devices. We tackle challenging problems in scheduler architecture, event processing, security rendering, hardware integration, and legacy system support while maintaining the high-quality standards our users expect. If you are passionate about building efficient compositing systems, optimizing for new hardware capabilities, and great battery life for millions of users worldwide, we want to hear from you. If you're excited about working across the full spectrum of compositing challenges—from scheduler design to event handling to security features—this role is for you. DESCRIPTION We're seeking a talented software engineer to join our UI Compositing team and grow into a key contributor to the core compositing infrastructure that powers all Apple devices. You'll have the opportunity to learn and work across different technical domains—from low-level system optimization to cross-platform feature development—while being mentored by experienced engineers. This role is ideal for someone early in their career who is eager to tackle diverse technical challenges and develop both depth and breadth in their engineering skills.
