About the role

What will you do at Apple?

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 and Apple Watch. Our goal is to enable developers

and HI designers to create exceptional visual experiences by efficiently

utilizing hardware acceleration and color technologies through compositing and

display. The technologies we develop are central to enabling enhanced

experiences across our platforms, including acceleration for Liquid Glass UI

material and presenting HDR content with the highest quality. Are you passionate

about building the rendering technologies that make interfaces feel alive? Do

you get excited about solving complex graphics challenges to deliver beautiful,

responsive experiences at scale? If creating world-class visual experiences

through innovative rendering architecture energizes you, this is your

opportunity.

DESCRIPTION

We are looking for a talented Software Engineer with rendering expertise to join

our UI Rendering team.

In this role, you will

contribute directly to the core
systems that manage how graphics are displayed across all Apple devices. You
will join the UI Rendering team and gain exposure to diverse technical
challenges across rendering configurations. You will work on core rendering
features, platform and device-specific code. You will implement features, debug
complex issues, and build hands-on experience across different areas of UI
Rendering. You will collaborate with GPU driver teams, display teams and Metal
framework engineers to understand how 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 will develop the ability to work across different
technical areas, a valuable skill for your career growth. As part of the team,
you will contribute to the Core Animation graphics compositing and rendering
engine that powers visual experiences across iPhone, iPad, Mac, Apple TV, and
Apple Watch. You will implement and build the graphics technologies that bring
our user interfaces to life, from foundational compositing systems to
cutting-edge visual effects. Working at the heart of our graphics stack, you
will bridge the gap between creative vision and technical reality. You will
partner directly with HI designers to prototype and productize new visual
concepts, collaborate with framework engineers to expose powerful rendering
capabilities, and work alongside our Metal and GPU teams to unlock the full
potential of Apple Silicon. From next-generation material systems to
sophisticated animation techniques, you will help shape the visual foundation
that defines how millions experience Apple products every day.
