Meta is seeking a Network Security Engineer to help protect and harden the global network infrastructure that underpins Meta's family of products and services. In this role, you will drive the design, implementation, and continuous improvement of security controls across Meta's large-scale network fabric, including edge, core, and data center environments. You will partner with network engineering, security operations, and product teams to identify vulnerabilities, define security architecture standards, and lead initiatives that reduce risk across the network infrastructure stack. This is a high-impact, technically deep role for an engineer who can operate at the intersection of network engineering and offensive and defensive security at global scale.
