iOS Engineer - Apple, Inc.

The Apple TV app brings together movies, shows, and live sports into one beautifully unified experience across Apple devices and dozens of third-party platforms. Our teams build the interfaces and interactions that millions of people rely on every day to discover, watch, and enjoy content they love. If you are passionate about crafting apps and experiences that ship at global scale, this is your opportunity to leave a lasting mark on how the world experiences Apple. In this role, you will architect and implement sophisticated media playback features using AVFoundation, CoreMedia, and AVKit across iOS and related Apple platforms. You will collaborate closely with framework, platform, and product teams to diagnose hard problems at the intersection of media pipelines, rendering, and system performance. Your work will directly influence the media experience on devices used by people around the world.Design and implement high-performance media playback features using AVFoundation, CoreMedia, and AVKit on iOS Build production-quality Swift and SwiftUI components that integrate seamlessly with underlying media pipelines Diagnose and resolve complex bugs spanning media decoding, synchronization, buffering, and AV rendering layers Profile and optimize CPU, GPU, and memory usage within media-heavy code paths using Instruments and low-level system tools Collaborate with cross-functional teams, including framework engineers, QA, and product managers, to define technical requirements and deliver robust solutions Extend and adapt media features across macOS and tvOS, ensuring consistent behavior and platform-idiomatic implementations Conduct rigorous code reviews, enforce engineering best practices, and contribute to internal technical documentation Participate in architecture discussions and drive technical decisions that balance correctness, performance, and long-term maintainability4+ years of professional iOS, MacOS, tvOS or VisionOS development Deep expertise in Swift, including protocol-oriented design, concurrency (async/await, structured concurrency), and performance-sensitive programming patterns Demonstrated ability to diagnose complex, multi-layered bugs involving media synchronization, codec behavior, or buffering anomalies Strong background in performance profiling using Instruments, including Time Profiler, Allocations, or Core Animation tooling Bachelors degree in Computer Science, Electrical Engineering, or a related technical discipline, or equivalent practical experience Track record of writing maintainable, well-tested Swift code at scale in a professional engineering environmentHands-on experience with SwiftUI for building declarative media-integrated user interfaces across Apple platforms Experience developing with a strong focus on media frameworks including AVFoundation, CoreMedia, and AVKit Familiarity with macOS and tvOS platform differences as they relate to media playback, window management, and HID input handling Proven experience building and shipping production applications that depend on real-time media playback, streaming pipelines, or AV capture Proficiency in Objective-C for interfacing with legacy or lower-level C-based media APIs within mixed-language codebases Experience with HTTP Live Streaming (HLS) internals, including manifest parsing, variant stream selection, and segment delivery optimization Exposure to Metal or Core Image for GPU-accelerated video post-processing or custom rendering pass integration
