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.


Messenger engagement has increased dramatically in terms of number of messages sent per active user. Messenger teams are focused on continuing to increase the user base and the number of mobile messages sent, and also largely focused on all the new product and feature development across the platform to engage all demographics (Visual messaging, Status, Realtime Communication, Expression, Groups, VoIP, Chat Heads, and Rich Attachment Types, like Selfies, Location, and Stickers.). We are evolving from a person to person platform into this much more robust platform where you can virtually do anything.
Messenger currently has 1.3 billion+ monthly active users. The scale of user impact here is tremendous. This team is responsible for user acquisition and retention strategy for Messenger which includes acquiring new users from FB, from other marketing channels, registration/login, needy user retention, contacts/connections and our Messenger Lite and emerging markets strategy.

I'm an engineering manager on our real-time infrastructure team, and my team focuses on GraphQL Subscriptions — a component of the widely-used GraphQL open source query language for APIs — that makes it easier for engineers to build real-time features into their products. At Facebook, this framework powers a number of features that people use every day, including comment-typing indicators and streaming reactions on live videos.

At Facebook, you have the opportunity to contribute to an incredibly wide range of infrastructure projects. While our engineers have a variety of expertise, they share a passion for solving complex engineering challenges at scale. It's humbling to know that everything you work on can potentially impact more than two billion people around the world.

We develop the network software for Facebook applications on iOS and Android platforms. This includes measuring and improving performance, reliability, security, and efficiency of network communication with Facebook servers. Getting the most out of a diverse set of worldwide mobile networks, and millions of handsets with a wide range of hardware capabilities is challenging as well as fun. All this while we play good citizens in these networks and are mindful of the device battery, storage, and data consumption.
