## About the role

Write code to understand 1B products . We stitch together the latest language, embedding, image, and segmentation models to build a true understanding of each and every product. Product pages vary greatly across retailers. We’ve built a computer-vision system that can understand any PDP, with no custom code or manual intervention on any site.

## What they're looking for

- Understanding what variants a product comes in might be even harder. We want to know what colors and sizes every shirt comes in, and what configurations customers can order for a new couch
- Lately, we’ve been ideating about how to return “good” results, which we’ve learned is not just the highest keyword/semantic match
