About the role
Every call, stream, and agent conversation running on LiveKit passes through our real-time media backend. It is the layer that ingests, transforms, and delivers audio and video at a scale of billions of calls a year — and it is the foundation the rest of the product is built on.
What they're looking for
- You've built critical real time media systems and pipelines that real customers depended on — you wrote the code, not just the integration
- You know the WebRTC stack from the inside: ICE, DTLS-SRTP, RTP/RTCP, congestion control, SDP negotiation
- You're a strong systems programmer in Go, Rust, C/C++, Java, or C# (Go preferred)
- You design asynchronous and multi-threaded systems, and can debug them under production load
- You communicate clearly and thrive with high individual ownership on a small team

As a Backend Engineer on the real-time media team, you'll own real time media distribution end to end: the interaction with real time clients, the distributed mesh allowing fast and reliable media distribution all over the world, and the new systems that customer-facing features depend on. Today a very small team covers this surface, so the scope is unusually large for one engineer — you'll set direction on reliability, performance, and protocol adoption (including newer transports like MoQ/WARP) rather than...
