Software Engineer, App Store

Apple Services Engineering is one of the most exciting examples of Apples long-held passion for combining the liberal arts and technology. We are the people who power Apple TV, Apple Music, Apple Podcasts, Apple Books, and the App Store. Our products operate at massive scale, delivering a huge variety of entertainment to customers in more than 150 countries and over 35 languages, and meeting Apples high expectations for performance and quality at every step. Our engineers build secure, end-to-end solutions: the custom software that processes creative work, the tools our providers use to deliver media, the server-side systems, and the APIs behind many Apple services. We use those systems to build delightful, easy-to-use customer experiences, increasingly enhanced by AI and generative AI. Thanks to Apples unique integration of hardware, software, and services, engineers here get behind a single unified vision, one that always includes a deep commitment to privacy, a core Apple value. Although Services is a bigger part of Apples business than ever, these teams remain small, nimble, and cross-functional, which means greater visibility and a wider array of opportunities than you might expect. If you care about the details that make an interface feel effortless, you will find a lot to love here. As a Frontend Engineer on Apple Services Engineering, you will build the next generation of customer- facing user experiences for some of the worlds most widely used subscription services. You will work day to day in HTML, CSS, JavaScript, and TypeScript alongside modern component frameworks and build tooling, partnering closely with design, product, and backend engineers to ship interfaces that are fast, accessible, and beautiful at global scale. This is a hands-on engineering role where craft matters. The surfaces you build are seen by hundreds of millions of people, so attention to detail, a high bar for quality, and a genuine investment in performance and accessibility are essential. You will also have the opportunity to help surface AI- powered and generative AI capabilities in consumer-facing interfaces, translating complex model behavior into experiences that feel simple and intuitive. We are looking for someone who is self-motivated and drives their commitments to completion, who collaborates generously, and who enjoys mentoring as much as being mentored.

Develop reusable UI components and shared frontend libraries that scale across multiple products, surfaces, and localized markets. Partner with design, product, and backend engineers to turn concepts into production experiences, and to shape technical direction early rather than after the fact. Optimize performance across load time, rendering, and runtime behavior, and measure the impact of your changes rather than assuming it. Champion accessibility and internationalization as product requirements, ensuring experiences work for every customer across 150+ countries and 35+ languages. Write and maintain automated tests at the unit, integration, and end-to-end levels, and help strengthen the teams testing and CI practices.
