Quora

Quora’s mission is to share and grow the world’s knowledge. We are a web-scale Library of Alexandria, a place where people go to learn about anything and share everything they know. At Quora, we use Machine Learning in almost every part of the product - feed ranking, answer ranking, search, topic and user recommendations, spam detection, etc. Within the past year we released a large question sincerity dataset, improved our statistical tests for ratio metrics, and introduced a new feature that allows people to curate collections and form communities around shared interests and tastes. As a Machine Learning expert, you will have a unique opportunity to have high impact by advancing these systems, as well as uncovering new opportunities to apply Machine Learning to the Quora product. As a ML Infrastructure Expert, you will play a key role in developing tools and abstractions that our other developers would build on top of.
