Principal Software Engineer, Applied AI Services

About the team

Shopper Journey Services (SJS) is Zillow’s engine for authenticated user intent and a core enabler of Home Details Page (HDP) experiences. We gather rich, explicit and implicit signals from authenticated shoppers and co‑shoppers, refine them into durable models, services, and display‑ready data, and activate those capabilities across Zillow’s ecosystem to deliver personalized, high‑quality experiences. Our charter spans two tightly connected areas: User Intent & Applied AI, where we build the pipelines, services, and evaluation capabilities that turn user signals into intelligence and AI‑powered experiences, and the HDP Backend Platform, where we power HDP with robust, low‑latency, display‑ready data. AI is both a product capability and an engineering accelerator for this team, and we are investing in LLM‑ and ML‑powered workflows, evaluation, and agentic systems while modernizing our conventional backend stack.
