Facebook's mission is to give people the power to share, and make the world more open and connected. Through our growing family of apps and services, we're building a different kind of company that helps billions of people around the world connect and share what matters most to them. 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 make the world more open and accessible. Connecting the world takes every one of us—and we're just getting started.Facebook's datacenter footprint is constantly growing to adapt to the vast amount of new services we provide to people. This results in a dramatic scaling challenge that our engineers have to deal with on a daily basis. Not only we need to build and evolve the physical infrastructure that connects myriads of servers together, but also ensure that the network is running smoothly and meets strict performance goals. And with the introduction of our own switching software(FBOSS) and our networking products (Wedge and Six-pack) we have entered into a new era of unprecedented opportunities to re-think traditional networking and iterate quickly in an area that was previously very closed to innovation. Facebook's datacenter network engineering team is actively looking for people with passion to solve difficult problems and innovate at fast pace. Datacenter networking at Facebook is multi-faceted discipline and covers all layers, starting from physical (fiber and optics), actively using distributed routing protocols such as BGP and topping with our own software stack running on our network devices. Reach out to us if you are eager to innovate and contribute to our mission. This position is full-time and located our Dublin offices.
