Apple is where individual imaginations gather together, committing to the values that lead to great work. Every new product we build, service we create, or Apple Store experience we deliver is the result of us making each other’s ideas stronger. That happens because every one of us shares a belief that we can make something wonderful and share it with the world, changing lives for the better. It’s the diversity of our people and their thinking that inspires the innovation that runs through everything we do. When we bring everybody in, we can do the best work of our lives. Here, you’ll do more than join something — you’ll add something. At Apple AIML Evaluation, you will be part of a team that makes it possible for Apple engineers to innovate ML driven product features rapidly and at scale. The team’s large scale distributed Annotation platform enables current and future Apple intelligence products by generating high quality critical data that facilitates Apple Intelligence and other cutting edge ML technologies. Imagine what you could do in a team like this, where great ideas have a way of becoming great products, services, and customer experiences very quickly. Bring passion and dedication to your job and there’s no telling what you could accomplish!
The AIML Annotation Platform team provides frameworks and services for enabling effective data annotations across all of Apple, while protecting user privacy. As a member of the team, you’ll have the opportunity to work with the team of highly skilled engineers to build reliable backend systems.
