Security Platform Engineer, Google Cloud Public Sector

As 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.

Responsibilities:

• Deploy, configure, and manage cloud security platform tools and technologies, including Security Information and Event Management (SIEM), Intrusion Detection/Prevention Systems (IDS/IPS), and Cloud Workload Protection Platforms (CWPP).
• Develop and implement security monitoring and logging strategies.
• Investigate and analyse security incidents, including identifying root causes, determining the scope of impact, and taking appropriate containment and remediation actions.
• Perform forensic analysis to identify and investigate suspicious activity.
• Automate security tasks and workflows to improve efficiency and effectiveness.

Minimum qualifications:

• Bachelor's degree in Computer Science, Information Security, a related field, or equivalent practical experience.
• 5 years of experience in security engineering, offensive security (Red Team/Purple Team), or platform engineering roles.
• Experience with infrastructure-as-code and GitOps (e.g., Terraform, Helm, ArgoCD) and cloud-native security orchestration.
• Experience with Kubernetes security (e.g., workload isolation, RBAC, network policies) and container orchestration.
• Experience in scripting and development languages (e.g., Python, Go) for building custom security tooling, automation, and exploit Proof-of-Concept (PoCs).
• Active, or the ability to obtain, a Developed Vetting (DV) UK security clearance.

Preferred qualifications:

• Advanced offensive security certifications (e.g., OSCP, OSEP, OSCE, GXPN).
• Experience in conducting full-scope Red Team engagements and Purple Team exercises in cloud-native environments.
• Experience developing custom exploits, adversary emulation scenarios, or security automation frameworks for internal testing.
• Knowledge of cloud-native logging, monitoring, and Security Information and Event Management (SIEM) integration for detecting sophisticated adversary tactics.
• Understanding of Kubernetes attack surfaces, including container escapes, privilege escalation, and lateral movement techniques.
• Current and active UK Developed Vetting (DV) Security Clearance.
