Spotify
We think this is a rare opportunity to be part of Spotify's groundbreaking journey as we evolve from an audio-first platform to also become a world-class video service. From offline playback to adaptive streaming with optimized video quality, you will be part of a team that defines how video will be consumed by hundreds of millions Spotify users. Our next challenge is to move more of our pre-render video pipeline, things like decoding, timing, synchronization and adaptive streaming from higher-level native integrations down into a performant, portable C++ stack. By driving this space alongside our existing players, you will shape the APIs, abstractions, and optimizations that make video on Spotify seamless everywhere: across iOS, Android, desktop, and beyond. We think you have many years of solid hands-on experience with video in code, from transcoding, streaming, demuxing, to adaptive bitrate selection and presentation of frames and audio samples. With that type of background this is a very good opportunity to expand your impact to help us at Spotify drive innovation in a space that's becoming increasingly vital to our growth. Joining us now will enable you to greatly influence our journey and make a lasting impact for the years to come.

Being a technical leader means that you are actively coding (in C++ with Swift and/or Kotlin), writing easy to understand documents and presenting for larger groups and key leaders. Debug complex performance issues across operating systems, device types, and networks. Optimise Spotify's AV stack by driving pre-render logic from platform-specific frameworks like AVFoundation into a cross-platform core to reduce duplication and increase consistency and device reach. Design and implement low-level C++ video components that handle decoding, synchronization, and adaptive playback with minimal overhead. Share expertise in low-level video systems, raising the bar across Spotify engineering. Who You Are A seasoned professional with a proven track record in senior roles, bringing a wealth of expertise and leadership to the table. Passionate about coding and hands-on problem-solving, while actively shaping and driving key strategic decisions. Strong understanding of decoding, synchronization, adaptive bitrate streaming, and frame-level control. Over 8 years of deep, hands-on experience in the video playback domain. Experience with platform-level frameworks like VideoToolbox, MediaCodec, or AVFoundation internals and motivated to generalize that work into reusable C++ systems. A deep understanding of video streaming technologies, with expertise in delivery protocols and the nuances of modern streaming ecosystems.
