Staff Rust SDK Engineer

About the Role

Join our world-class engineering team as a Staff Rust SDK Engineer to build the LiveKit Rust SDK and high-performance core modules, pushing the boundaries of real-time communication and developer experience.

Responsibilities

• 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, guiding and mentoring engineers with less Rust experience, promoting best practices, and fostering 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.

Requirements

• Strong expertise in Rust and 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-Haves

• Experience with LiveKit technologies.
• Background in real-time systems, networking, and performance optimization, potentially with WebRTC or related technologies.

Role Impact

In this role, you’ll play a key part in shaping the Rust developer experience for LiveKit, while also building 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. 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.
