Summary 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 an exceptional senior software engineer who combines deep technical expertise with versatility and strong leadership to work across our UI Compositing team. You will contribute to the core compositing infrastructure that powers all Apple devices, working on challenges that span from low-level system optimization to cross-platform feature development. This role requires the ability to context-switch between different technical domains while maintaining the same high standards of quality and performance.
As part of the UI Compositing team, you will play a central role within our graphics stack. Your work will span multiple areas of compositing infrastructure—optimizing how frames are scheduled and displayed, implementing visual security features, handling user input events, and maintaining critical system code. You'll work on problems that balance performance with battery life, ensure security and privacy, and maintain the reliability of systems that billions of users depend on daily. Partnering with GPU driver teams, Display teams, and Metal framework engineers, you'll help shape compositing infrastructure across iOS, macOS, tvOS, and watchOS.
Our team values versatility, deep technical expertise, and a proactive approach to problem-solving. We work in complex codebases where autonomy, strong debugging skills, and the willingness to dive deep into intricate system-level code are essential. The ability to move fluidly between different technical challenges and work across the full compositing stack is critical to success in this role.
Minimum Qualifications
5+ years of experience in software development with strong systems programming background
Deep familiarity with Unix environments, system programming, and low-level debugging
Proficiency in C/C++ with understanding of memory management, threading, and performance optimization
Strong debugging skills with ability to trace complex issues through multiple layers of abstraction using tools like lldb, dtrace, and Instruments
Experience with performance analysis and optimizations.
Understanding of compositing, frame timing, vsync, and display technologies
Proven track record of leading technical initiatives and driving projects from concept to completion
Demonstrated ability to work across multiple technical domains and context-switch effectively
Self-driven approach to testing, validation, and ensuring code quality
Demonstrated ability to mentor others and provide technical leadership
Bachelor's or Master's degree or equivalent in Computer Science or related field
Preferred Qualifications
Experience with compositing systems, scheduler design, or graphics infrastructure
Experience with GPU Programming, Metal, or modern graphics APIs
Familiarity with advanced display technologies and variable refresh rate systems
Understanding of display hardware and GPU architectures
Experience with event-driven systems and input handling
Experience working with large legacy codebases and incremental modernization strategies
Experience working across multiple Apple platforms (iOS, macOS, tvOS, watchOS)
Experience integrating software with hardware capabilities
Proven ability to define processes and drive automation to increase productivity
Experience shipping consumer products at scale and working across hardware and software
Versatility to work across different technical areas and problem domains
Apple is an equal opportunity employer that is committed to inclusion and diversity. We seek to promote equal opportunity for all applicants without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, Veteran status, or other legally protected characteristics.
