Lead the vision - Help define the technical direction, contribute to the long-term technical roadmap, and support strategic initiatives in the search platform.

Build for scale, reliability, and efficiency - Lead design and implementation of critical components to evolve the platform to ensure scalable, efficient, low-latency search and retrieval across a large corpus of data.

Improve developer velocity - Drive innovations that reduce time-to-production.

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 merchants 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 scalable, reliable, fast, and provide high app quality.

Product Velocity

- Search powers more than 20 verticals, including 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.
