Engineering Manager, Search Platform



Software Engineering, Other Engineering
San Francisco, CA, USA · Sunnyvale, CA, USA
Posted on Wednesday, February 7, 2024

About the Team

We are on a mission to build a reliable, fast and scalable search platform for DoorDash. This team is responsible for providing capabilities like search indexing, retrieval and ranking to help consumers find the most relevant merchants and products on DoorDash. We work across three dimensions.

Scale - DoorDash has millions of stores and billions of items. We index over a billion documents in our index and serve thousands of QPS running expensive operations on millions of documents per second. This requires the platform to be reliable, fast and provide high app quality.

Product Velocity - Search powers many verticals like Retail, Discovery (Feed) and Ads with several engineers building new product experiences on top of the platform. This requires the platform to enable product teams to experiment with new ideas with minimal friction.

Relevance - Machine Learning engineers regularly experiment with new relevance algorithms to improve search quality. This requires the platform to provide relevance capabilities like query understanding and multi-stage ranking to improve recall and precision.

The team is a part of Core Consumer org which owns the top of the conversion funnel from the initial landing page to checkout across iOS, Android, and Web platforms. With a universal Search bar on the home page, as Doordash expands into new verticals like Grocery, there is a growing need to help consumers easily find what they want, so the opportunity is massive and we are just getting started!
