Key job responsibilities
- Develop and maintain our video playback, broadcast, and real-time SDKs for iOS

- Build reliable unit, integration, and end-to-end tests
- Stay current on Apple platform developments, media frameworks, and streaming technologies

A day in the life
You might start the morning investigating a customer-reported playback issue, digging into AVFoundation behavior across iOS versions. By midmorning you're building new playback functionality in our HLS Player SDK including API design, implementing for functionality in C++, crafting platform specific bindings, and testing across a range of devices. After lunch you're reviewing a teammate's PR for the real-time SDK, discussing codec tradeoffs with the backend team, and running integration tests to make sure nothing regressed. The work spans the full media stack on Apple platforms and no two days look the same.
