Full Job Description
The On-device ML Performance team has the responsibility to analyze latency, memory, power and numerical correctness of the latest machine learning models running on Apple SoC's, and to make Apple's ML software stack take full advantage of the capabilities in Apple's ML accelerators. The work from this cross functional team enables model developers' decisions to optimize performance via advanced techniques such as quantization, sparsity, performance and accuracy tradeoffs. The work of this team impacts all new Apple HW and ML Inference on them.

Our group is looking for an On-device ML Performance Engineer, with technical expertise in computer architecture, performance, memory, power, ML model architectures and on-device ML inference. The role entails deep analysis of ML inference from the SW stack and low level drivers to HW debug involving CPU, GPU, Apple Neural Engine, system memory and power.

Description

As an engineer in this role, you will be primarily focused on analyzing and optimizing the performance of the latest ML models on the latest iPhones and Mac's. You will work with models created by the most popular ML frameworks (PyTorch, MLX, etc) and will analyze the inference of those models on device to ensure the stack achieves full machine performance on Apple Silicon. The role also includes scripting, coding, and generation of utilities and debug tools to extract, analyze, and report performance and power related metrics for Apple HW. The ideal candidate will have a passion for ML model architectures and ML inference, deep knowledge of GPU and CPU, computer architecture and memory, compilers and HW drivers.

Minimum Qualifications

Experience with ML inference, quantization, performance and accuracy

Familiarity and experience with the most popular ML architectures (e.g. LLM's, Diffusion models, CNN's)

A passion to explore and learn about the latest advances in ML model design and architecture, particularly as related to model implementation on HW and on-device inference

Familiarity with Operating Systems, embedded systems, and CPU/GPU HW architectures

Highly proficient in Python/C++ and shell scripting

Familiarity with Linux or macOS

Exceptional clarity in verbal and written communication, including the ability to present and lead discussions in larger groups

Preferred Qualifications

Masters or PhDs in Computer Science or relevant disciplines.

Experience with Apple's CoreML, MPS Graph, Metal Performance Shader's or MLX frameworks

Experience with any on-device ML stack, such as TFLite, ONNX, ExecuTorch, etc.

Experience with any ML authoring framework (PyTorch, TensorFlow, JAX, etc.).

Experience with Apple's App development framework such as Xcode, Swift, Objective-C

Experience with any compiler stack (MLIR/LLVM/TVM etc.)

About Apple

Apple is a corporation that designs, manufactures, and markets mobile communication and media devices, personal computers, portable digital music players, and sells a variety of related software, services, peripherals, networking solutions, and third-party digital content and applications. Apple provides many products and services, including iPhone; iPad; iPod; Mac; Apple TV; a portfolio of consumer and professional software applications; the iOS and OS X operating systems; iCloud; and accessories, service, and support offerings. It sells its products worldwide through its retail stores, online stores, direct sales force and third-party cellular network carriers, wholesalers, retailers, and value-added resellers to the consumer and also sells third-party iPhone, iPad, Mac and iPod compatible products, including application software and accessories through its online and retail stores. Introduced in 1984, the Macintosh was the first widely sold personal computer with a graphical user interface (GUI). That feature and others such as an improved floppy drive design and a low-cost hard drive that made data retrieval faster helped Apple cultivate a reputation for innovation. Apple was named as the most admired company in the United States in 2008 and in the world from 2008 to 2012 by the Fortune magazine. The company was founded by Steven Paul Jobs, Steve Wozniak, and Ronald Gerald Wayne on April 1, 1976, and is headquartered in Cupertino, California.
