• Build and secure scalable Azure and AWS environments, ensuring every VNET, Firewall, and PaaS service is hardened against modern threats while optimized for cost and performance.
• Drive the transition to a modern operating model by automating security controls using Terraform or similar tooling, ensuring compliance is baked in by default.
• Beyond prevention, you will own the technical execution of Disaster Recovery and Business Continuity plans, ensuring our global operations remain uninterrupted.
