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 LiveKit is an equal opportunity employer and does not discriminate on the basis of any characteristic protected by applicable law.
