Network Security Engineer

Meta’s Network Security team is seeking an experienced engineer to help secure our global Data Centers, Backbone, Optical Infrastructure, and PoP networks. We do this by working extensively across the Meta family of products, including Facebook, Messenger, Instagram, WhatsApp, Oculus, AR/VR, and AI efforts where we identify and solve security problems across network infrastructure.

You will be responsible for building and implementing security tools to protect Meta networks utilizing a combination of development, in-house services and open source tools. You will be directly involved in building and influencing security features within our open source network hardware platform (FBOSS) which helps serve traffic for billions users worldwide.

We are looking for a candidate with a passion for security and innovation, who will research and develop new solutions to help protect our infrastructure and our users through a defense in-depth approach. Candidates should thrive on finding security issues and eradicating them as well as a desire to make life hard for bad actors. With focuses that range from large scale DDoS, routing security, security tool development, defense against internal and external attacks there’s lots of room to push your skill set beyond simply protecting the network with firewalls.Network Security Engineer Responsibilities

Preferred Qualifications

• Understanding of defense-in-depth strategies used to protect critical network infrastructure and its supporting components.
