Build AI agents that generate, validate, and maintain test coverage across Airbnb's codebase
Airbnb's Quality Platform team builds AI-native systems that embed LLMs directly into the testing lifecycle — test generation, agentic PR validation, and coverage maintenance as code changes. This is a fullstack, applied-AI role spanning client tooling (TypeScript, Swift, Kotlin) and backend services (Java, Python). Good prep if you want to practice explaining how you'd design an LLM-backed agent for a developer workflow and defend it against reliability and scale concerns.

Tell me about a time you used prompt engineering or RAG to make an AI system more reliable
Describe building both the developer-facing tooling and the backend service behind a feature
How would you keep an AI-powered test system from becoming a CI/CD bottleneck at scale
Tell me about identifying and removing a bottleneck in a testing or CI workflow
How do you explain a complex AI system design to someone without an ML background
