Yelp has billions of pieces of user-contributed content, millions of users and business listings, and hundreds of thousands of advertising customers—all of which are constantly growing. Our machine learning engineers turn raw data into valuable signals by building end-to-end ML systems from feature ETLs, as well as deploying predictive models in production and building the ML platforms that those models rely on. These systems power applications like search ranking, ads targeting, push notifications, and photo understanding.

The Spam team is responsible for ensuring that Yelp is a safe platform to use and reflects real user experiences by leveraging machine learning techniques.

Yelp engineering culture is driven by our values: we’re a cooperative team that values individual authenticity and encourages creative solutions to problems. All new engineers 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’re all about helping our users, growing as engineers, and having fun in a collaborative environment

This opportunity requires you to be located in the Republic of Ireland.
