Backend Engineer I

Advertising, subscriptions and transaction fees each bring in a significant share of revenue. Our engineering, trust and safety, and customer support teams work across offices in Los Angeles and several other countries. We started in 2007 and have grown to about 800 people. Product reviews happen on Thursdays, with demos of whatever shipped that week.
