• Evaluate, design and deploy hypervisor solutions to support system requirements.
• Create secure Windows 10/11 Gold Image builds, with security as the primary consideration.
• Harden operating systems by disabling non-essential services and telemetry to reduce the potential attack surface.
• Apply appropriate vendor, NCSC and equivalent security standards.
• Support the design and implementation of Multi-Factor Authentication (MFA) capabilities.
• Support system management capabilities including logging, updates and patching.
• Maintain consistency across multiple deployments through strict version control and repeatable build processes.
• Produce clear and comprehensive technical documentation.
