Are you ready to help us deliver the next groundbreaking Apple products?","responsibilities":"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

Preferred Qualifications

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)

Minimum Qualifications

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
