About the role

Zillow is looking for a Senior Applied Scientist on the Applied Reasoning team within the Agentic AI organization to research and develop advanced LLM-powered reasoning systems specialized in the real estate domain. In this role, you'll take a hands-on approach to prototyping, evaluating, and deploying agents capable of deep, multi-step reasoning, accurate use of tools/skills, and contextual decision-making tailored to real estate use cases. Your work will focus on eliciting deep reasoning and strong information synthesis from LLMs through test-time scaling and targeted post-training, supported by rigorous evaluation frameworks to improve the reliability and quality of agent responses in real estate use cases.

As a Senior Applied Scientist in the Agentic AI team, you will: 

• Design, prototype, and build advanced agentic systems capable of highly autonomous, context-aware, and adaptive interactions across diverse real estate use cases

• Apply test-time scaling and post-training techniques to develop agents that can reason, collaborate, compete, or negotiate in dynamic, goal-driven environments to fulfill user needs.

• Define and refine evaluation and experimentation processes for LLM-driven applications.

• Stay at the forefront of agentic AI research and innovation, bringing emerging techniques into practical application to shape product direction.

• Contribute to the broader scientific community through publications, conference presentations, and internal knowledge sharing

• Mentor and guide junior scientists and engineers, promoting best practices in applied research, scalable agentic architecture, and responsible AI development.
