Job details

About LiveKit LiveKit is building the infrastructure layer for the voice-driven era of computing. Our platform gives developers everything they need to build, test, deploy, scale, and observe agents in production. Founded in 2021, LiveKit powers voice AI applications for OpenAI, xAI, Salesforce, Coursera, Spotify, and thousands of others, collectively facilitating billions of calls each year. About You Most product designers want to design for everyone. This role is for someone who'd rather design for one very specific, very opinionated person: the developer at 2am trying to figure out why their voice agent just failed a call. You'll design the tools developers use to test, evaluate and debug AI agents — a category that's still being invented, with no established patterns to copy. If dense data, real-time systems and reading a stack trace sound more fun than intimidating, keep reading.
