Facebook Network Specialist in Seattle, Washington
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.

We are the team that builds the Real-Time media stack for low-latency media connections at global scale. Do you want to build new features and improve existing products that connect people in real-time via Messenger, Facebook, Oculus, and more? Want to solve unique, large scale, highly complex technical problems? Facebook is looking for a hands on Software Engineering Lead with mobile networking experience. The candidate should have experience with lossy and unreliable networks, cellular and wifi stacks, bandwidth estimation and optimization, writing and debugging C/C++ code. This engineer will be personally responsible for the networking stack in a real-time communication engine, which includes real-time bandwidth estimation, buffering, and QoS across various devices and networks. This engineer will additionally support and optimize the real-time transport between two peer devices, single devices for media streaming to very large groups, and participating devices in a group video chat. Challenges this engineer will face include instantly estimating changes in bandwidth (below round trip latencies), buffering QoS to support real-time transmission of media while providing a more reliable stream for broadcasting, and supporting group video chats between multiple participants without degrading bitrates due to a single participant's slow connection. This position is full-time and based in our Seattle, WA office.
