About the role

Backend Engineer focusing on real-time media distribution within LiveKit’s SFU and real-time mesh, driving latency reduction, reliability, and adoption of modern media transports.

Responsibilities

  • Build new real time systems to support customer-facing features, from first design through production
  • Drive down latency and improve call quality across every session on the platform
  • Assess and adopt modern media and transport protocols, including MoQ/WARP
  • Partner with client SDK, infrastructure, and product teams on cloud mesh architecture and cross-cutting reliability work, and serve as the internal expert those teams consult

Qualifications

  • You've built critical real time media systems and pipelines that real customers depended on — you wrote the code, not just the integration

  • You're a strong systems programmer in Go, Rust, C/C++, Java, or C# (Go preferred)
