Whether you’re looking for a plumber, contractor, or an electrician, we believe that better matching and accurate pricing in Yelp’s Service marketplace results in higher engagement from business owners and users, who are a critical part of what allows Yelp’s business model to thrive.</p><p style="margin: 0px;"> </p><p style="margin: 0px;">We are looking for an entrepreneurial, self-driven machine learning scientist who will help invent the future of optimization at Yelp.
