• Troubleshoot and resolve infrastructure issues promptly; perform root‑cause analysis and implement preventative measures.
• Collaborate closely with other teams (applications, security, user support) to support new services or changes in infrastructure.
• Oversee third‑party vendor and service provider relationships for anything infrastructure‑related.
• Prepare and present reports on infrastructure health, incidents, planned improvements, budget impacts.

• Experience in backup, disaster recovery, storage solutions, load balancing, patch management.
• Solid knowledge of security controls, monitoring tools, vulnerability management.
• Familiarity with automation, scripting, and configuration management (e.g. PowerShell, Python, Terraform, Ansible).
• Ability to mentor, review technical work, set infrastructure standards.
• Strong communication skills; able to explain technical concepts to non‑technical stakeholders.
