About the team
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. We are building a Zillow World Model: a model of the housing market and the people in it that our agents can reason with. This is a very new field, and the team works on open-ended problems in close partnership with product, engineering, platform, and data teams.About the role
You'll build the demand side of the Zillow World Model: the representation of who is in the market, what they'll pay, and how that demand clears against supply. You will get to:
- Build latent state-space or world models that represent market participants and how their state evolves, with calibrated uncertainty and multi-step rollouts
- Turn large-scale user behavior (search, engagement, session trajectories) into structured demand representations, such as willingness to pay and conversion from attention to demand
- Apply causal inference to observational data to separate what a model can and cannot say about "what if" scenarios
- Connect learned representations to economic quantities like demand curves, market tightness, and clearing dynamics
- Lead ambiguous, open-ended research end to end and share technical direction with scientists and engineers
Who you are
Must-haves
- PhD in Computer Science, Machine Learning, Economics, Statistics, or a related field, or equivalent research experience
- Hands-on experience building world models or sequential dynamics models (e.g., RSSM/Dreamer-family, JEPA-style latent prediction, or event-sequence transformers), or modeling demand from large-scale behavioral data
- Practical experience with causal inference in observational settings, such as quasi-experiments, instruments, or policy discontinuities
- A track record of delivering on open-ended research projects and providing technical leadership to other scientists
- Proficiency in Python and ML frameworks such as PyTorch or JAX
Nice-to-haves
- Economics fluency: market microstructure, search-and-matching, or structural / discrete-choice demand models
- Experience with two-sided marketplaces, real estate, or other long-horizon consumer markets
- Background in simulation, model-based reinforcement learning, or LLM post-training with an interest in world models
- Publications at top ML or economics venues
