AIML Frontend Engineer, Annotation Platform & Agentic UI Experiences

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 others 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. Its 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 youll do more than join something youll add part of Apples central data annotation engineering team you will help shape the interfaces through which human expertise and machine intelligence meet. Our platform powers high-quality dataset creation and annotation across every vertical at Apple from Siri to Photos from iPhone to Vision Pro. Were looking for a Senior Software Engineer who brings genuine depth in frontend engineering and a designers sensibility: someone who executes with precision elevates the people and work around them and cares as much about how something feels as how its built.

The AIML Annotation Platform provides the tools frameworks and services that make large-scale privacy-focused data annotation possible across Apple. As a Senior Software Engineer on our team you will be a key contributor to the web frontend of our annotation and quality platform a complex multi-role product used daily by annotators quality analysts ML engineers and internal partners have a mature eye for design systems. You can articulate why a pattern works spot where an evolving product breaks established conventions and translate visual and interaction language into guidance that an engineering team can actually use. You are as comfortable reasoning through a component architecture as you are in a design critique and you bring both rigour and taste to each. That same rigor extends to your engineering craft you hold a high bar for performance testing and architectural soundness in everything you work well in interdisciplinary settings. You have led frontend work in cross-functional teams coordinating across design backend and product stakeholders not as the sole contributor but as the person who brought the pieces together.
