SeniorSoftwareEngineer,MediaBackend

LiveKit is building the infrastructure layer for the voice-driven era of computing. Our platform gives developers everything they need to build, test, deploy, scale, and observe agents in production. Founded in 2021, LiveKit powers voice AI applications for OpenAI, xAI, Salesforce, Coursera, Spotify, and thousands of others, collectively facilitating billions of calls each year. YOU'LL THRIVE AT LIVEKIT IF YOU: - Care deeply about producing clean, reliable, and practical systems - Consistently step up to own challenging technical problems - Are known for figuring things out, even in unfamiliar domains - Value clear communication and simple, understandable designs - Like building systems that ship, run in production, and improve over time The best way to impress us is with thoughtful Issues and/or PRs on our Github repos 😊 ABOUT THIS ROLE: We’re looking for a Senior/Staff Engineer to own and improve the media pipeline and services that surround the real-time core: the systems that bring media into LiveKit sessions and get it back out again. Recordings, ingest from arbitrary sources, exports to wherever a session needs to land, format and codec handling across a long tail of inputs — this is the connective tissue that makes voice agents useful beyond the live conversation. The scope is broad, the surface area is large, and the impact is visible across every product built on LiveKit. Experience with media pipelines, systems, and algorithms is valuable, but we weigh programming fundamentals, judgment, and the ability to learn quickly just as heavily. We expect you to reason from first principles, shape technical direction through your own implementation, and leave the codebase better than you found it. Your work will be felt across every LiveKit-powered voice agent — in every recording reviewed, every session replayed, every pipeline that feeds them. WHAT YOU’LL DO: - Design, build, and optimize the media pipeline and services around LiveKit's real-time core - Build di
