You will be directly involved in building and influencing security features within our open source network hardware platform (FBOSS) which helps serve traffic for over 3 billion 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. 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.
