# Principal Data Scientist

About the team At Zillow Group, our mission is to help more people get home. The CoreTech Org delivers on this mission by building the foundational platforms, data, and developer capabilities that power every consumer, partner, and employee experience at Zillow.You will work most closely with the Connections Platform (CP) - the engine that turns consumer interest into a connection with the right partner, owning the conversational experience, the lead funnel and follow-up workflows, and the shared agent services that sit underneath both. Increasingly, that experience is powered by LLM-based and agentic systems: agents that qualify leads, summarize and extract intelligence from conversations for partner teams, and drive proactive outreach. Beyond CP, you will be a measurement partner for the broader CoreTech Org - the foundational platforms every consumer, partner, and employee experience at Zillow is built on - wherever a hard data science problem needs an owner. These are platforms with hundreds of touchpoints and dozens of dependent teams - and they have historically been among the hardest places at Zillow to measure well. CP itself is mid-transformation, shifting from NLP to LLM
