eBay | www.ebay.com | New York | NYC | Full Time | ONSITE | REDACTED_EMAIL | VISA ok We are hiring experienced data scientists to change the way eBay does advertising. eBay's old advertising strategy was 3rd party focused (Ads that sent people off eBay). Our CEO said that strategy has changed. We need ads that keep people on eBay and offer better choices for our buyers. We are the team blowing up the old strategy and doing something better. You can move the needle when it comes to eBay's profit. We are a small team in a growing remote office. This is a unique opportunity to learn search engine and recommendation technology which rank eBay's 1+ billion active items. We apply cutting edge machine learning techniques on petabytes of data and thousands of Spark/YARN nodes. This includes deep learning, XGBoost and online learning. Our interview consists of two phone screens. Then you come onsite to meet the team and do a code test. The role will be 50% production coding and 50% research. REDACTED_EMAIL | Ask for Adam
