About the Team
Your future team is the heart of our AI conversational experience, dedicated to balancing operational efficiency with a world-class user journey. As a Senior Staff Data Scientist, you will drive success across two critical workstreams: Support XP, which focuses on optimizing end-to-end support through high-quality FAQ retrieval and intelligent human escalation (including the integration of Wall-e), and AI Central, where you will architect the "brain" of our system. Your challenge is to orchestrate specialized agents from across the company into a single, coherent experience—shaping its personality, governing the agent topology, and maintaining global user context. This is a high-impact role where you will define the standards for intelligence, behavior, and rigorous evaluation to scale our AI tools to 100% of our users.
