Network Engineer, Deployment and Support

(Odense, Denmark)

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'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 face on a daily basis. Not only do 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. With the introduction of our own switching software (FBOSS) and our open networking hardware projects (Wedge, Wedge100, and Backpack), 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 Edge & Network Service (ENS) team is actively looking for passionate people to help us tackle the unique set of challenges and opportunities we face, while contributing to our company mission of connecting the world. Our team is the execution arm of the Facebook network team and is responsible for the deployment and support of all production networks (Edge, Backbone, Optical, and Datacenter) as well as our content delivery network (CDN) across the globe. This truly global team offers a unique career opportunity to work with all of the latest network technologies and talented engineers solving some of the most complex problems in the industry. This position is full-time and based in our Odense datacenter in Denmark.
