Senior Infrastructure 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 hiring a Senior Infrastructure Engineer to join the small team that owns the cloud foundation all of LiveKit's real-time products run on — reliability, networking, and shared platform primitives like CockroachDB, NATS, and Nebula. LiveKit is at 3B+ calls per year, and the reliability surface area is growing faster than team capacity. There are three buckets of work on this team: (1) Product SRE — jumping directly into the product codebase and implementing reliability goals within it: load balancing, load shedding, instrumentation, scalability, efficiency. (2) Self-service platform tooling — building frameworks and libraries so product teams can self-serve reliability without Infra as a bottleneck. (3) Reactive work — on-call, urgent feature requests, reliability debt. The goal is to minimize #3 through #1 and #2. There is still meaningful reliability debt to work through when you join. We're being honest about that up front. The upside: small team, high ownership, and real influence over how a global real-time platform scales. 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 work hard and can build and ship fast can clearly explain complex technical concepts to other engineers are a fast learner, frequently picking up new languages and tools The best way to impress us is with thoughtful Issues and/or PRs on our GitHub repos. What You'll Do Ramp on LiveKit's global architecture — CockroachDB, NATS, Nebula, Kubernetes — and map where reliability debt lives Ship product SRE work directly in the product codebase: load balancing, load shedding, instrumentation, scalability, efficiency Build and extend common tooling so product teams can self-service reliability without Infra as a bottleneck Participate in the on-call rotation and help resolve recurring reliability patterns Bring informed systems opinions that improve how the team makes architectural decisions Who You Are Strong Go fluency — you write production Go, not just read it Kubernetes at depth (internals + networking), not just ops Comfortable working directly in product codebases, not only around them Debug by looking behind the curtain, not just at dashboards Track record of building or operating production distributed systems at scale Nice to Have Experience with CockroachDB, NATS, or similar distributed systems Google SRE or equivalent high-scale background Nebula, WireGuard, or similar overlay networking experience Open source contributions, especially on infra or developer tools Experience in realtime, audio/video, or low-latency systems 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.
