Apple is the best place to do on-device machine learning, and this team sits at the heart of that discipline, interfacing with research, SW engineering, HW engineering, and products.\nThe team builds critical infrastructure that begins with onboarding the latest machine learning architectures to embedded devices, optimization toolkits to optimize these models to better suit the target devices, machine learning compilers and runtimes to execute these models as efficiently as possible, and the benchmarking, analysis and debugging toolchain needed to improve on new model iterations. This infrastructure underpins most of Apple’s critical machine learning workflows across Camera, Siri, Health, Vision, etc., and as such is an integral part of Apple Intelligence.\nOur group is looking for an On-Device ML Quality Infrastructure Engineer. The role involves building and maintaining the infrastructure used to connect, validate, and benchmark the components of the On-Device Machine Learning stack.\nDescription\nWe are building the first end-to-end developer experience for ML development that, by taking advantage of Apple's vertical integration, allows developers to iterate on model authoring, optimization, transformation, execution, debugging, profiling, and analysis.\nAs an engineer in this role, you will build and maintain the infrastructure that keeps every component of our ML stack robust and testable, and that lets our engineers move fast without breaking things. This means owning build and CI systems, developing automation frameworks, and ensuring high-quality, low-friction workflows from commit to validation.\nBeyond pure infrastructure, this role contributes directly to quality: writing and expanding test suites, developing robustness tests (such as fuzz testing), running performance benchmarks, and tracking regressions across the stack. You will also collaborate with Apple's broader CI and infrastructure teams to improve validation speed and scale.\nThis is a great role for an engineer who cares deeply about software quality and wants to work at the intersection of systems infrastructure and cutting-edge ML.\nMinimum Qualifications\nBachelors in Computer Science or relevant disciplines.\nBuild systems (CMake, Bazel) and CI/CD experience\nStrong programming and software design skills in Python.\nIn depth knowledge of quality practices and fundamentals, including test planning, automation, and performance evaluation.\nExcellent collaboration and communication skills.\nPreferred Qualifications\nMasters in Computer Science or relevant disciplines.\nExperience with any ML authoring framework (PyTorch, TensorFlow, JAX, etc.).\nExperience with standard ML architectures such as Transformers, CNNs or Stable Diffusion a strong plus.\nExperience with fuzz testing tools or methodologies\nExperience with performance profiling and analysis tools\nFamiliarity with GenAI tooling for developer productivity or test generation.","description_format":"text","description_chars":3169,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":true},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Operating
