Network Security Engineer / Remote / Firewall

Our client is a large enterprise organization looking for a Network Security Engineer to join their team on a contract basis. This fully remote role will focus on network security, firewall security and policy analysis, configuration compliance, vulnerability management, and security risk remediation while supporting EST business hours and collaborating with U.S.-based and offshore teams.
