A system administrator is an essential IT professional who is responsible for providing a reliable work environment for an organization—from server and network performance to security and all other areas that keep an organization’s IT systems running smoothly. System administrators must have an in-depth understanding of computer software, hardware, and networks and are highly skilled, valuable members of an organization.

• Design, organize, modify, and support an organization’s computer systems, including operating systems, business applications, security tools, web servers, email systems, and user hardware (laptops, PCs).
• Quickly resolve any system failures and troubleshoots issues.
• Upgrade and manage hardware and software.
• Research upcoming products, service protocols, and standards in support of systems software procurement and development efforts.

At a high level, system administrators are responsible for system performance, design, and reliability and the security and optimization of computer systems. The breadth of these responsibilities is dependent upon the size and scale of an organization’s IT-related infrastructure.
