About the role

This is a Principal role, meaning you are the senior-most technical authority on the pod.
Why This Role Matters Setting the Architecture: You define the multi-stage ranking and RL architecture that determines which short-form asset is surfaced to every user - directly shaping CTR, discovery velocity, and long-term retention.
Org-Level Quality Bar: You raise the technical bar across the Shortform pod and adjacent pods, anticipate systemic risks (data, modeling, feedback loops), and influence the broader Applied ML roadmap.

Set Technical Strategy: Own the multi-quarter technical roadmap for short-form ranking, candidate generation, and Post-training RL.
Architect End-to-End Systems: Design the multi-stage ranking architecture spanning retrieval, ranking, re-ranking, and RL-based policy optimization.
Cross-Pod Influence: Partner with Content Understanding, ML Platform, Core Science, and Product to align short-form personalization with broader Discovery strategy.
