SeniorHybridSoftware Engineering
We design Spotify’s consumer experience—end to end, moment to moment, across every screen, platform, and partner integration. Our mission is to make listening feel effortless, personal, and joyful for billions of users around the world. That means turning complexity into clarity across hundreds of touchpoints—from our mobile and desktop apps to the smart speakers, TVs, cars, and integrations where Spotify shows up every day. If it touches a consumer, we shape it. We bring deep insight into human behavior, design, and technology to craft experiences that feel intuitive, expressive, and unmistakably Spotify.
At Spotify, we’re building the best way to experience audio and video — everywhere, every time. As listening and watching on TV continues to grow, we’re investing deeply in native, video-first playback experiences that are fast, reliable, and feel effortless.
The Native Playback team sits at the heart of Spotify’s TV strategy. We integrate Spotify’s playback experience with the native players and media frameworks available on each platform. Our work happens close to the system — where performance, reliability, and quality truly matter — and directly impacts how millions of people experience Spotify every day.

- Own critical playback areas including buffering strategies, playback state handling, A/V synchronization, adaptive bitrate configuration, track selection, and rendering paths
- Debug complex performance and reliability issues across multiple layers — from application logic to OS-level frameworks and hardware acceleration
- Partner closely with Playback platform teams and device teams to ensure shared APIs and designs translate cleanly into real-world TV implementations
- Improve test coverage, tooling, and observability to detect regressions and speed up iteration cycles
- Contribute to thoughtful technical design discussions and raise the bar for playback quality through code reviews and knowledge sharing

- You are comfortable working close to the OS and media framework layer and diagnosing issues that span multiple system boundaries
- You have experience contributing to the design and evolution of scalable technical systems across platforms
- You are confident debugging performance and reliability issues using logs, traces, profilers, and system diagnostics tools
- You collaborate effectively across teams and communicate technical trade-offs clearly
- You care deeply about delivering reliable, high-quality playback experiences for millions of users
