Software Engineer - Trust and Safety

(Menlo Park, CA)

Facebook's mission is to give people the power to build community and bring the world closer together. Through our family of apps and services, we're building a different kind of company that connects billions of people around the world, gives them ways to share what matters most to them, and helps bring people closer together. Whether we're creating new products or helping a small business expand its reach, people at Facebook are builders at heart. Our global teams are constantly iterating, solving problems, and working together to empower people around the world to build community and connect in meaningful ways. Together, we can help people build stronger communities — we're just getting started.

Facebook is where people connect, and in recent years more people have been using Facebook to connect in another way: buying and selling with each other. This activity started in Facebook Groups and has grown substantially. More than 450 million people visit buy and sell groups each month — from families in a local neighborhood to collectors around the world.

To help people make more of these connections, we built Marketplace, a convenient destination to discover, buy and sell items with people in your community. Marketplace makes it easy to find new things you'll love, and find a new home for the things you're ready to part with.

We are looking for an experienced Engineer with background in fraud prevention to help define a system that will protect users and keep Marketplace a safe place to do business.
