Apple is where individual imaginations gather together, committing to the values that lead to great work. Every new product we build, service we create, or Apple Store experience we deliver is the result of us making each other's ideas stronger. That happens because every one of us shares a belief that we can make something wonderful and share it with the world, changing lives for the better. It's the diversity of our people and their thinking that inspires the innovation that runs through everything we do. When we bring everybody in, we can do the best work of our lives. Here, you'll do more than join something - you'll add something.\\n\\nApple Vision Pro is a revolutionary spatial computer that seamlessly blends digital content with your physical space. It will allow us to do the things we love in ways never before possible - all while staying connected to the people around us. Join the RealityKit framework team building the character animation systems that bring digital beings to life on Apple's spatial computing platform. This role combines deep expertise in real-time animation with the opportunity to shape how developers create expressive, responsive characters for immersive experiences.\n\nYou will design and implement animation runtime systems including skeletal animation pipelines, blend trees, inverse kinematics solvers, and procedural motion techniques. Your work will directly impact how characters move, react, and feel present in mixed reality environments-where physical plausibility and performance constraints create unique technical challenges.\nWe're looking for an engineer who understands both the artistic intent behind great character animation and the systems engineering required to deliver it on resource-constrained devices. You'll collaborate closely with artists, designers, and framework engineers to build animation technologies that are powerful enough for AAA-quality experiences yet accessible to developers across skill levels. Proven industry experience in animation systems, game engines, or related fields\nBS in Computer Science, Computer Graphics, or equivalent degree/experience\nStrong knowledge of C++ and real-time animation architectures\nSolid understanding of 3D mathematics (linear algebra, quaternions, transforms)\n Excellent communication skills for cross-functional collaboration with artists and engineers\nExperience implementing skeletal animation, state machines, or blend systems\nExperience with inverse kinematics, physics-based animation, or procedural techniques\nHands-on experience with AR/VR animation challenges (latency, prediction, presence)\nContributions to animation tools or artist-facing workflows\nFamiliarity with RealityKit, ARKit, or SceneKit
