About the role

Software Engineer specializing in real-time graphics rendering. Contribute to CoreAnimation, Metal command generation, and low-level compositing to deliver high-fidelity UI materials and animations across Apple devices, focusing on performance, power efficiency, and visual quality.

Responsibilities

  • Cross-Functional Collaboration: Collaborate with teams across UI Frameworks, System Experience, HI Design, Metal, and GPU Hardware to deliver rendering solutions for complex graphics challenges.
  • CoreAnimation Pipeline & Metal Development: Implement and optimize UI rendering architecture and features within CoreAnimation across Apple platforms, contributing to efficient Metal command generation and pipeline performance.
  • Multi-Platform Experience & Material Innovation: Partner with framework and design teams to implement rendering support for new UI materials (e.g., blur, Liquid Glass effects), system animations, and visual design language evolution across Apple Watch, Home accessories, iPhone, iPad, Mac, and Vision products.
  • Latency & Battery Engineering: Profile and optimize rendering performance to minimize latency across CPU and GPU pipelines and improve power efficiency for UI rendering across the device lineup.
  • Visual Quality & System Health: Drive rendering quality, correctness, and visual fidelity by diagnosing and fixing glitches, flickering, frame drops, and visual corruptions in multi-layered rendering contexts.
  • Modern Engineering Workflows: Leverage modern engineering practices—including agentic coding workflows—to accelerate development iteration and deliver high-quality code.

Qualifications

  • 3+ years of experience in software development
  • 2+ years of experience with real-time rendering and computer graphics
  • Experience delivering graphics or rendering features in production software.
  • Strong expertise in C/C++ programming, and GPU-accelerated rendering pipelines.
  • Hands-on experience with modern graphics APIs (Metal, Vulkan, or DirectX) and low-level rendering optimization.
  • Foundational understanding of Operating Systems, Computer Architecture, and CPU/GPU programming including memory subsystems
  • Strong debugging and triaging skills for complex, multi-layered systems issues
  • Excellent collaboration skills with cross-functional teams on complex software projects
  • Demonstrated expertise in graphics performance analysis, profiling, and optimization across CPU/GPU boundaries.
  • Practical experience incorporating modern AI-assisted workflows and agentic coding tools into software engineering practices.
  • Bachelor's or Master's degree in Computer Science, Computer Engineering, or related field, or equivalent experience.
  • Familiarity with tile-based deferred rendering (TBDR) GPU architectures and advanced graphics programming
  • Experience with low-level Metal/Vulkan/D3D12 command generation, multi-threaded rendering architectures, or CPU/GPU synchronization models.
  • Experience with client/server or multi-process graphics architectures
  • Experience working on consumer graphics products
  • Experience with automated testing frameworks for graphics rendering
  • Knowledge of or interest in CoreAnimation, layer-based compositing systems, scene graph architectures, or multi-process graphics engines.
  • Experience delivering graphics and UI rendering capabilities across diverse hardware constraints (mobile, wearable, spatial computing, home/embedded, desktop).
  • Knowledge of color management, HDR presentation, wide color gamut workflows, or shader programming (MSL/GLSL/HLSL).
  • Familiarity with iOS, macOS, watchOS, or visionOS software development in Swift or Objective-C.
