We’re looking for a Senior iOS Video Player Engineer with deep, production-level experience in live video streaming to work on high-quality playback experiences across iPhone, iPad, and Apple TV. The focus is squarely on media and streaming, with hands-on ownership of live HLS playback, AVPlayer behavior, performance tuning, and playback reliability at scale. You’ll be working on challenges like fast startup times, buffering behavior, live edge management, latency, and real-world playback stability. This role is designed for someone who can join and contribute quickly in a mature streaming ecosystem.
Key Responsibilities

Optimize HLS playback using AVPlayer, with a strong focus on startup time, buffering behavior, latency, and playback stability.
Troubleshoot and resolve complex playback issues in live streaming environments, including errors, stalls, and drift from the live edge.
Tune playback performance at scale to ensure reliable, high-quality viewing experiences.
Use video analytics and QoE metrics to diagnose issues and improve real-world playback performance.

Proven experience building and maintaining video players or live playback components for iOS/tvOS.
Strong hands-on experience with HLS and AVPlayer, including tuning and troubleshooting playback behavior, especially for live streaming.
Demonstrated ability to debug and optimize playback performance, including rebuffering, startup time, and playback stability.
Familiarity with video streaming protocols, live playback concepts (latency, live edge, drift), ABR logic, and DRM integration.
Experience using video analytics or QoE metrics (e.g., Mux, Conviva) to diagnose and improve real-world playback performance
