Description

About the team Zillow has the richest housing market data in the industry. You help us build out a foundational model that leverages a representation of who is in the market, what they’ll pay, and how that demand clears against supply. The Agentic Foundations team is a focused group of 15–20 applied scientists within Zillow’s broader Agentic AI organization, building the foundational AI technologies that power the next generation of home shopping experiences. This Principal Applied Scientist will help build the Zillow World Model: a single, uncertainty-aware model of the housing market that ties together supply, demand and macro conditions such as mortgage rates and policy. Today, bespoke models like Zestimate, Time-to-Pending and Listing Soon each answer one question well. The foundational “World” Model aims to answer the multi-step “what if” questions consumers actually ask, such as “If I list at $500K, when will it sell?” or “I want at least $800K; what should I list at?”, as consistent projections of one market state, and to serve those answers to Voyager, Zillow’s AI Mode, as a tool. This is a very new field and an open-ended research effort. You will partner with the World Model working group (listing-state modeling, market simulation and evaluation) and with product, engineering, platform and data teams. Zillow observes both sides of the housing market at a depth no one else can, so this work can directly help guide users toward their goals. About the role Build the d
