Security Platform Engineer

The UK Security Operations (SecOps) team in Google Public Sector delivers, operates and secures private cloud services. We aim 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.
