Applied Scientist

As an Applied Scientist on Trust & Safety you will employ your analytical skills to detect and understand content spam at Yelp. You will set up robust statistical experiments to characterize user behaviour, assess our models through careful statistical analysis, and build end-to-end machine learned models that impact hundreds of millions of consumer contributions. Yelp engineering culture is driven by our values: we’re a cooperative team that encourages individual authenticity and 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’re all about helping our users, growing as engineers and scientists, 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.
