Lead Security Engineer, gTech Risk Solutions

About the job

Our Security team works to create and maintain the safest operating environment for Google's users and developers. Security Engineers work with network equipment and actively monitor our systems for attacks and intrusions. In this role, you will also work with software engineers to proactively identify and fix security flaws and vulnerabilities.

gTech Risk Solutions is executing a strategic transformation from a reactive, program-led organization to a proactive engineering powerhouse. Operating as a federated security partner to Google's central security organizations, we design and build highly contextualized security solutions tailored specifically for the gTech business ecosystem. Our mission is upfront risk prevention through technical delivery excellence, shifting the paradigm from unsustainable "risk-chasing" to "prevention by design."
