Device ML Infrastructure Engineer; Compiler & Runtime

Cupertino, California, United States Machine Learning and AI

Imagine being at the forefront of an evolution where modern AI meets the elegance of Apple silicon. The On-Device Machine Learning team transforms groundbreaking research into practical applications, enabling billions of Apple devices to run powerful AI models locally, privately, and efficiently. We stand at the unique intersection of research, software engineering, hardware engineering, and product development, making Apple the leading destination for machine learning innovation.

Our team builds the essential infrastructure that enables machine learning at scale on Apple devices. This involves onboarding powerful architectures to embedded systems, developing optimization toolkits for model compression and acceleration, building ML compilers and runtimes for efficient execution, and creating comprehensive benchmarking and debugging tool chains. This infrastructure forms the backbone of Apple’s machine learning workflows across Camera, Siri, Health, Vision, and other core experiences, contributing to the overall Apple Intelligence ecosystem.

If you are passionate about the technical challenges of running sophisticated ML models across all devices, from resource-constrained devices to powerful cluster, and eager to directly impact how machine learning operates across the Apple ecosystem, this role presents a great opportunity to work on the next generation of intelligent experiences on Apple platforms. We are seeking an ML Infrastructure Engineer with a specific focus on building the best execution engine and compilation toolchain that employs our compilers infrastructure and the world’s most efficient, portable, and extensible runtime, and which is capable of optimizing and driving ML models efficiently on Apple products and services, current and future.

We’re building an end-to-end developer experience for machine learning development that brings to bear Apple’s vertical integration. This allows developers to iterate on model authoring, optimization, transformation, execution, debugging, profiling, and analysis. This role is to function as the glue between our compiler technology, the runtime components, the kernel libraries, and the low-level hardware compilers to enable the execution of ML across a wide variety of devices and use cases.

We’re seeking a highly motivated software engineer who is creative, skilled, and passionate about machine learning, common compiler optimizations, and system software engineering in the fast-paced and dynamic field of machine learning.

• Help lead and deliver on critical initiatives for on device machine learning infrastructure.
• Design, build, and maintain critical machine learning infrastructure that powers Apple’s machine learning features.
• Collaborate with downstream hardware compilers to best leverage Apple’s machine learning hardware.
• Collaborate with first and third party users to adopt our infrastructure and apply protocols when they implement machine learning on Apple devices.
• Ensure our infrastructure can run optimally for a wide range of first and third party machine learning models.

• Bachelors in Computer Science, Engineering, or related subject area.
• Highly proficient in C++. Familiarity with Python and Swift.
• Familiarity with Operating Systems and Embedded Programming.
• Sound understanding of ML fundamentals, including common architectures such as Transformers.
• Good communication skills, including ability to communicate with multi-functional audiences.

• Experience with any on-device ML stack, such as TFLite, ONNX, Execu Torch, etc.
• Experience with open source machine learning models (Mistral, Phi, Gemma, Huggingface, etc)
• Experience with any compiler stack (MLIR/LLVM/TVM/...).
• Experience with any ML authoring framework (PyTorch, Tensor Flow, JAX, etc.).
• Experience with machine learning accelerators and GPU programming.
