Yelp Software Engineer - Machine Learning

Yelp has hundreds of millions of pieces of user-contributed content, millions of users and business listings, and hundreds of thousands of advertising customers–and all of these numbers are constantly growing. Yelp’s machine learning engineers turn raw data into valuable signals by building end-to-end ML systems, from feature ETL to deploying predictive models in production, as well as by building the ML platforms that these models rely on. These systems power applications like search ranking, ads targeting, push notifications, and photo understanding. Our data teams banter about Bandits, know their way down a Gradient, and aren’t too Naïve to kick back in our office. Yelp engineering culture is driven by our values: we’re a cooperative team that values individual authenticity and encourages creative solutions to problems. We enable all new team members to deploy working code their first week, and your impact will only grow from there with the support of your manager, mentor, and team. At the end of the day, we are all about helping our users, growing as engineers, and having fun in a collaborative environment. We’d love to have you apply, even if you don't feel you meet every single requirement in this posting. At Yelp, we’re looking for great people, not just those who simply check off all the boxes.
