About the jobAs a part of the UK Security Operations (SecOps) team in Google Public Sector, you will deliver, operate and secure private cloud services. Your aim is to provide the flexibility, reliability, and scalability of public cloud for customers with exceptionally high security requirements that can only be met in a private cloud environment. You will deliver and operate these private cloud deployments for the most critical customers, helping scale, secure and maintain the deployment whilst working closely with Google product teams to continually improve our technology.

In this engineering-centric role, you will require deep technical expertise in cloud environments, Kubernetes security, and platform automation. You will work closely with Incident Response, Platform Engineering and Security Architects to ensure that security validation and defensive hardening are seamlessly integrated into infrastructure and operational workflows. Your role will require participation in a rotating on-call schedule outside of core business hours and over the weekend to ensure security incidents and critical operations can be supported.
