Staff SDK Engineer

About the Role

Join LiveKit as a Staff SDK Engineer to revolutionize multimodal AI interfaces by powering real-time communications across platforms. This role offers the unique opportunity to own and guide the design, implementation, and long-term direction of LiveKit SDKs, impacting developers globally.

What You'll Do

• Own one or two SDKs (such as Python, Go, Rust, or other SDKs), becoming the go-to engineer responsible for design, development, and long-term maintenance.
• Contribute to high-performance shared modules that power LiveKit’s multi-language SDK ecosystem.
• Collaborate closely with cross-functional teams (client SDKs, agents, cloud teams, PMs) to ensure smooth integration, shared standards, and consistent developer experience.
• Diagnose and solve complex cross-platform performance or reliability issues, often at the intersection of mobile, desktop, web clients and servers.
• Improve CI/CD, testing, and make releases across SDKs, strengthening release pipelines and developer tooling.
• Push the boundaries of real-time performance, optimizing systems for low latency, scalability, and efficiency.

Who You Are

• Strong engineering fundamentals and experience shipping production-quality code in at least two of: Rust, Python, Swift, Kotlin, TypeScript/JS, C++, or C#.
• Comfortable moving between languages and toolchains, picking up new technologies quickly as the problem demands.
• Built or maintained SDKs, APIs, or developer-facing frameworks, with an eye for usability and long-term maintainability.
• Hands-on experience with CI/CD, testing, and release processes in multi-language environments.
• Collaborative, pragmatic, and communicative, able to work closely with other engineers to solve tough cross-platform challenges.

Bonus Skills

• Understanding of real-time systems, WebRTC, or network performance, and enjoyment of profiling and optimizing complex codebases.
• Experience with cross-platform SDK design or bridging native modules (e.g., Rust/C++ to mobile or web).
