LiveKit is looking for a Staff SDK Engineer to power real-time communications across platforms. You'll help build SDKs, shared modules, and developer tooling that enable teams worldwide to create high-quality, low-latency applications. As a generalist who enjoys moving between layers of the stack, you'll become the owner of one or more SDKs, guiding their design and long-term direction.
What You'll Do
- Own one or two SDKs (such as Python, Go, Rust, or others), becoming the go-to engineer 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 and a consistent developer experience.
- Diagnose and solve complex cross-platform performance or reliability issues.
- Improve CI/CD, testing, and release processes across SDKs.
- Optimize systems for low latency, scalability, and efficiency.
What We're Looking For
- Strong engineering fundamentals and experience shipping production-quality code in at least two of: Rust, Python, Swift, Kotlin, TypeScript/JS, C++, or C#.
- Comfort moving between languages and toolchains, picking up new technologies as needed.
- Experience building or maintaining SDKs, APIs, or developer-facing frameworks with a focus on usability and maintainability.
- Hands-on experience with CI/CD, testing, and release processes in multi-language environments.
- Collaborative, pragmatic, and communicative style, able to work with other engineers on cross-platform challenges.
Nice to Have
- Understanding of real-time systems, WebRTC, or network performance, with experience profiling and optimizing complex codebases.
- Experience with cross-platform SDK design or bridging native modules (e.g., Rust/C++ to mobile or web).
Technical Stack
- Rust
- Python
- Swift
- Kotlin
- TypeScript/JS
- C++
- C#
Team & Environment
You'll join a small, world-class engineering team and work closely with cross-functional teams including client SDKs, agents, cloud teams, and product managers.
Benefits & Compensation
- Health, dental, and vision benefits.
- Flexible vacation policy.
- Competitive salary and equity package.
