As a member of the Personalization ML Platform team, you will be responsible for designing and building machine learning (ML) frameworks and underlying infrastructure that power experiences across various Apple Services. Your work will involve developing frameworks that can run both on the cloud and on devices. Cloud-based frameworks must be scalable to handle billions of requests per day, while device-based frameworks must operate with minimal memory and compute resources. You will collaborate with a diverse team of experts, including ML researchers, Core OS engineers, infrastructure engineers, user interface designers, tools engineers, and technical writers. This dynamic environment encourages lively discussions and the exchange of ideas. Individuals with a broad perspective and a willingness to learn from others will thrive in this multi-disciplinary setting.
