Connecting people with great local businesses


Terabytes of data: high resolution photos, 120+ million text documents in more than a dozen languages, real-time location data, semantic business information collected from users and business owners, and more… If this gets your heart racing, you just might be a good fit for our data mining teams at Yelp!  

We’re a passionate and diverse group of engineers who can work across disciplines to provide incredible insights to our users.  We own the whole stack: scoping the problem by digging through data in Redshift and Jupyter, designing a solution by reading cutting edge research and industry best practices, training a model using gradient boosted decision trees and deep learning, and finally scaling it to millions of users, businesses, and advertisers.

Develop a learning-to-rank model on Search?  Design a clever new feature to keep web-scraping bots at bay?  Model the complex interactions between an advertiser, their budget, user behavior, and business inventory?  All in a day’s work for our data teams! Check out the details below:
