Security Platform Engineer, UK Security Operations

Our client is a global technology company. As a part of the UK Security Operations (SecOps) team in our Public Sector, you will deliver, operate and secure private cloud services. You will 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.

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 our client product teams to continually improve our technology.

As a Security Platform Engineer, you will play a critical role in designing, building, and managing cloud-native security platforms with a strong emphasis on Kubernetes-based environments. You will be at the intersection of security and engineering, developing scalable tooling, automating security controls, and enabling robust detection and response capabilities across our cloud infrastructure.

In this role, you will require deep technical expertise in cloud environments, Kubernetes security, and platform automation. You will work closely with Incident Response Engineers and platform teams to ensure that security is seamlessly integrated into our 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 can be swiftly resolved. Minimum
