• Establish and manage an Ansible framework to streamline infrastructure provisioning, configuration management, and repeatable deployments.
• Oversee file server operations and support storage platforms, including configuration, performance tuning, and ongoing administration.
• Deliver multiple infrastructure-focused projects covering server implementation, automation improvements, and overall environment optimization.
• Apply security standards and strengthen systems through hardening measures, access controls, and risk-reduction practices.
• Support the organization’s virtualized environment, including administration and upkeep of Proxmox-based systems.
• Work with technology leadership to define priorities, while independently driving assigned initiatives through completion.
• Troubleshoot infrastructure issues, recommend practical improvements, and help maintain reliable day-to-day system operations.
