Build the UI that lets Airbnb engineers run and trust an agentic testing platform

This is a senior frontend seat on Airbnb's Quality Platform team, building the web surfaces that expose an LLM-driven agentic testing platform to thousands of internal engineers. The role sits at the intersection of Quality Engineering, Infrastructure, and Applied AI, so the interview will probe React/TypeScript depth, developer-tooling UX judgment, and comfort visualizing large volumes of test data.
