## Job description

info_outline About the job There's no such thing as a "safe system" - only safer systems. Our Security team works to create and maintain the safest operating environment for Google's users and developers. As a Security Engineer, you help protect network boundaries, keep computer systems and network devices hardened against attacks and provide security services to protect highly sensitive data like passwords and customer information.

Security Engineers work directly with network equipment and actively monitor our systems for attacks and intrusions. You also work with software engineers to proactively identify and fix security flaws and vulnerabilities. You use your industry experience to own and drive the resolution of complex security incidents, policy questions and technical security issues. Part of Google Cloud, Mandiant is a recognized leader in dynamic cyber defense, threat intelligence and incident response services.
