Here’s what to look for when hiring a system administrator.

What Does a System Administrator Do?

A system administrator (SA) is responsible for installing, configuring, maintaining, and securing an organization’s IT infrastructure. They manage servers, operating systems, user accounts, networks, backups, and system performance while troubleshooting technical issues that affect employees and business operations.

Modern system administrators also play an important role in cloud infrastructure, cybersecurity, automation, and disaster recovery, helping organizations maintain reliable and secure technology environments.

Security is now a core responsibility for system administrators. Look for candidates who understand access controls, multi-factor authentication, patch management, endpoint security, and security best practices that reduce organizational risk.
