Role Overview
We are seeking a Senior Cloud Platform Engineer with deep expertise in Google Cloud Platform (GCP), Kubernetes, and High-Assurance UK Defence environments.
In this role, you will design, deploy, and maintain mission-critical, sovereign cloud infrastructure for sensitive national security operations. You will operate at the intersection of modern cloud-native software engineering and strict defense compliance—building automated, air-gapped platforms using Google Distributed Cloud air-gapped (GDC air-gapped) and GKE Enterprise capable of supporting tactical edge analytics and disconnected containerised workloads.
Requirements
Key Responsibilities
- Sovereign Infrastructure as Code (IaC): Design, build, and maintain enterprise-grade GCP environments and Sovereign Landing Zones using Terraform and Ansible
- Kubernetes Orchestration: Manage, scale, and secure production GKE and GKE Enterprise clusters in air-gapped or low-bandwidth environments
- High-Assurance Security Architecture: Implement Zero-Trust network topologies, Private Google Access, Service Controls, and IAM policies aligned with NCSC Cloud Security Principles, JSP 604, and MoD Secure by Design (SbD) frameworks
- Air-Gapped & Edge Deployments: Operate fully disconnected, sovereign cloud nodes (GDC air-gapped) and handle offline artifact management (e.g., container image mirroring, local Helm repositories, offline Terraform providers)
- DevSecOps & Policy-as-Code: Build secure CI/CD pipelines incorporating container scanning, cryptographic image signing, secret management (Vault/GCP KMS), and automated policy enforcement (OPA/Gatekeeper)
- Data Sovereignty & Isolation: Configure private interconnects, network firewalls, and outbound-only proxies to guarantee strict data sovereignty and prevent data exfiltration
