• Design and implement API's for Apple's Neural Engine - defining how clients load, compile, schedule and execute models on device
• Architect APIs which provide client control of model lifecycle management, memory allocation strategies, multi-model scheduling, and concurrent execution — ensuring the runtime scales with new hardware capabilities
• Collaborate deeply with driver, firmware and compiler teams to co-design the runtime-to-silicon interface, ensuring new hardware features are exposed with correct abstractions
• Profile and optimize end-to-end inference paths, identifying bottlenecks in scheduling, compilation, and inference execution
• Support clients in adopting APIs and ensuring efficient integration

• BS and a minimum of 10 years relevant industry experience
• Experience defining interfaces that are used by other teams or external developers, with attention to lifecycle, error handling, and forward compatibility
• Deep proficiency in C and C++ in large, production system software
• Understanding of runtime systems: process/thread models, memory management, IPC/RPC, and resource lifecycle
• Understanding of software-hardware interfaces: registers, DMA, command queues, or similar accelerator interaction patterns
• Experience shipping production system software

• Experience building or extending ML runtimes, inference engines, or accelerator driver stacks (e.g., TensorRT, ONNX Runtime, XLA, Metal, Vulkan compute, or similar)
• Familiarity with Swift/Rust or another memory-safe systems language
• Familiarity with ML model compilation pipelines and how runtime APIs interact with compiler outputs (graph IR, compiled binaries)
• Experience with multi-client runtime scenarios: arbitrating hardware access, managing priority/QoS, and handling client lifecycle (ex: connect, disconnect, crash recovery)
• Knowledge of neural network inference: operator execution, tensor memory layout, pipelining, and batching strategies
• Strong communication skills and experience working across team boundaries (framework teams, compiler teams, hardware teams)

At Apple, we're not all the same. And that's our greatest strength. We draw on the differences in who we are, what we've experienced, and how we think. Because to create products that serve everyone, we believe in including everyone. Therefore, we are committed to treating all applicants fairly and equally. We will work with applicants to make any reasonable accommodations.

At Apple, we believe accessibility is a fundamental human right. You’ll find that idea reflected in everything here — in our culture, our benefits and our digital tools. By welcoming as many perspectives as possible, we help you build a career where you feel like you belong.
