Software Engineer, Signal Platform

San Francisco

We are building a reliable platform for Pinterest engineers to produce and consume signals about pins, boards, and users. These signals power critical Pinterest product features, such as home feed, search, recommendations, ads, and trust & safety. The signal platform is also the foundation for our unified ML feature store. It provides a uniform way to access batch, incremental, and real-time generated data, and complete data governance capabilities: quality and freshness monitoring, lineage tracking, ownership, cost attribution and lifecycle management.
