Senior Data Scientist

Zillow Zillow · Consumer · Mexico City, Mexico

Senior Data Scientist at Zillow supporting customer communication platforms. Responsibilities include leading the design, development, and maintenance of WBR dashboards, analyzing complex datasets for performance insights, designing and executing A/B tests, building basic predictive or heuristic models for personalization and governance, and collaborating with data engineering and product teams. The role requires strong statistical concepts, experimental design, A/B testing, causal inference, SQL, Python/R, and data visualization tools.

What you'd actually do

  1. Lead the design, development, and maintenance of Weekly Business Review (WBR) dashboards and reports for the Connections, Conversations, and Communications Platforms, partnering with product teams to define and validate key performance metrics (e.g., connection rates, message reply rates, campaign performance).
  2. Analyze large, complex platform datasets (e.g., leads, conversations, campaigns) to provide timely, accurate performance insights and uncover trends, patterns, and opportunities for optimization across our communication channels.
  3. Design, execute, and analyze A/B tests and other experimental designs for feature launches and platform optimizations, including defining success metrics, applying causal inference techniques, and delivering clear post-test readouts and recommendations.
  4. Build and integrate basic predictive or heuristic models into platform features to enhance personalization and governance—for example, modeling the value/impact of communications across campaigns or developing conversation sentiment and engagement signals.
  5. Collaborate with data engineering and product teams to design and optimize data pipelines and new data products/tables (primarily in Databricks) that power WBRs, experimentation, and client-facing reporting, ensuring data integrity, usability, and scalability.
