• Integrate with backend APIs for content catalog, analytics, and player events.
• Ensure high performance, low memory usage, and smooth playback on both iOS and tvOS devices.
• Debug and resolve complex playback issues, buffering/latency problems, and platform-specific behaviors.
• Write clean, maintainable code following best architectural practices.
• Participate in code reviews and contribute to improving overall engineering standards.
• Stay up to date with Apple platform updates, new APIs, and best practices.

What you'll bring:

• 5–7+ years of professional experience in Swift development.
• Strong expertise with AVPlayer, AVFoundation, HLS streaming, and media playback architecture.
• Proven experience building and releasing iOS and/or tvOS applications.
• Solid understanding of UI frameworks (UIKit; SwiftUI is a plus).
• Experience with performance optimization, memory profiling, and debugging tools (Instruments, Console, etc.).
