You’ll be the primary front-end engineer on a focused pod within a 20+ person team, building internal video and media tooling used by teams supporting Apple Music, Apple TV+, and Sports. This is a high-impact, highly autonomous role ideal for someone who can balance UI polish with deep system understanding.You should be comfortable navigating a complex codebase, proposing UI architecture, and collaborating closely with backend and product partners. Our stack includes React/Svelte and TypeScript on the front end, with Java/Kotlin/Python services. While the role is front-end focused, the ability—or eagerness—to work across the stack is highly valued. You’ll partner closely with backend peers and be empowered to explore across the stack in an environment that values technical depth and curiosity.
