About the Team

Our team is responsible for optimizing, ranking, and presenting ads on behalf of our sellers on Etsy’s website and mobile apps. This is an opportunity for you to play a major role in connecting our buyers with Etsy’s 60+ million listings through our ML-fueled ad platform.

How can we help our sellers set bids to achieve the highest rate of return?
How do we rank millions of ads in a matter of milliseconds, so that we’re giving our buyers the best experience while maximizing revenue?
How can we detect bad actors in our system to protect sellers?
