AIML Sr OS Software Engineer, Evaluation

For the engineer that obsesses on how software can enable OS developers to evaluate and improve their features there is no better place than Apples Experimentation team. The Experimentation team builds an end-to-end platform spanning the OS data and server for all the Apple OSes operating at a scale of 2.5 billion devices. We are addressing key challenges to accelerate the adoption of AI and an experimentation culture mindset across all Apple products/services. We are seeking seasoned engineers that can push the boundaries of low-level operating system technologies while maintaining a customer-centric focus on the developer and user experience.

The mission of Evaluation is to measure understand and proactively improve all Apple features. We are looking for an experienced engineer to build and extend the experimentation system for Apple to use across all our operating systems. You will be responsible for the on-device daemon and framework that is at the heart of the experimentation platform. You will partner with feature teams across Apple to enable them to make a positive impact for the customers. You will ship code that runs on devices you use every day and powers a variety of Apple products. You will obsess over memory power performance in addition to the developer experience. Your technical leadership will drive critical design discussions elevate peers through code reviews and push the boundaries across the operating system.
