Our users come to Pinterest to explore ideas and run more than 80 billion search queries every month. Many of these queries represent exploratory search and shopping intent and are broad, which means that the search system should be able to deeply understand this intent, then help people explore content, personalize results, harness visual and multimodal signals effectively, and show the most engaging content up front. All of this means that Pinterest Search presents a unique challenge quite unlike other search systems and the opportunity to innovate on a product that only Pinterest can build.

We are looking for an exceptional Senior Staff Engineer to lead Search’s product and front-end strategy across iOS and other platforms such as Android and Web, spanning core product lines like Text Search, Visual Search, and Image Search.
