Staff Rust SDK Engineer

ABOUT LIVEKIT

LiveKit is building the infrastructure layer for the agentic era of computing. Our platform gives developers everything they need to build, test, deploy, scale, and observe AI agents in production. Founded in 2021, LiveKit powers voice and agentic AI applications for OpenAI, Salesforce, Spotify, Meta, and tens of thousands of other developers, collectively facilitating billions of calls each year.

ABOUT THIS ROLE

We're looking for a passionate Senior / Staff Rust engineer to help build both the LiveKit Rust SDK and the high-performance Rust core modules that power our real-time client SDKs across multiple platforms. You'll be joining a small, world-class engineering team focused on pushing the boundaries of real-time communication performance, reliability, and developer experience.

In this role, you'll play a key part in shaping the Rust developer experience for LiveKit, while also building the shared systems that other SDKs (Swift, Kotlin, TypeScript, Unity, Node, Flutter, C/C++, and more) depend on. You'll have the opportunity to work across deep systems layers and developer-facing abstractions, contributing to open-source software used by teams building real-time apps worldwide.

What makes this role unique is its dual focus: you'll build a robust, idiomatic Rust SDK while also designing core modules that serve as the performance-critical foundation for LiveKit's cross-platform ecosystem. Your work will directly influence how developers integrate real-time audio, video, and data streaming into their applications — from embedded systems to large-scale production apps.

As a Staff engineer, you'll help define architectural direction across SDKs and drive technical alignment across teams.

YOU'LL THRIVE HERE IF YOU:

- obsess over crafting code that is fast, reliable, and practical for the problem

- are known as the go-to person for tackling tough technical problems

- move quickly and ship high-quality systems with strong ownership...
