Description
We're seeking a motivated software engineer who is eager to learn systems programming and wants to work on compositing infrastructure. You'll work closely with experienced engineers who will mentor you as you contribute to the core systems that manage how graphics are displayed across all Apple devices. This is a great opportunity to build broad expertise in low-level systems programming while working on technology that impacts billions of devices.You'll join the UI Compositing team and gain exposure to diverse technical challenges across compositing infrastructure. You'll learn how systems coordinate hardware (displays, GPUs, processors) to deliver smooth visual experiences. You'll work on performance optimization, system features, input handling, and critical platform code. With guidance from senior engineers, you'll work on real features, fix bugs, and gain hands-on experience across different areas of compositing. Over time, you'll collaborate with GPU driver teams, Display teams, and Metal framework engineers to understand how all the pieces fit together.Our team values versatility, deep technical expertise, and a proactive approach to problem-solving. We work in complex Unix-based codebases where autonomy, strong debugging skills, and the willingness to dive deep into intricate system-level code are essential. You'll develop the ability to work across different technical areas—a valuable skill for your career growth.
