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
can clearly explain complex technical concepts to other engineers
are a fast learner, frequently picking up new languages and tools
We love seeing how you think. If you've contributed to our ecosystem or similar low-level Rust projects, feel free to point us toward your PRs or Issues.
What You'll Do
Design, build, and maintain the LiveKit Rust SDK and the shared Rust core modules that power LiveKit's multi-platform client ecosystem
Lead by example - guide and mentor engineers with less Rust experience, promote shared code and engineering best practices, and foster a culture of high-quality, maintainable, and testable Rust code
Collaborate closely with cross-functional teams (client SDKs, agents, cloud teams, PMs) to ensure smooth integration, shared standards, and consistent developer experience
Own the testing, CI/CD, and release processes for Rust projects, ensuring reliability and stability across environments
Profile and optimize performance in real-time, low-latency systems to push the boundaries of what's possible in LiveKit's SDKs
Contribute to SDK architecture and design decisions, shaping the long-term technical direction for both the Rust SDK and cross-platform SDK interoperability
Who You Are
Strong expertise in Rust with experience delivering production-quality libraries or SDKs
Collaborative and communicative, comfortable working across multiple teams and platforms
Experience developing SDKs or libraries for multi-platform clients (mobile, web, or embedded)
Understanding of testing, CI/CD, and release best practices in modern Rust ecosystems
Nice to Have
You've worked with LiveKit technologies
Experience with real-time systems, networking, and performance optimization
Familiarity with WebRTC or related technologies
Our Commitment to You
An opportunity to build something truly impactful to the world
Contribute to open source alongside world-class engineers
Competitive salary and equity package
Health, dental, and vision benefits
Flexible vacation policy
