Sysadmins are vital roles within every company’s IT department, often covering a wide swath of technology support. Common sysadmin tasks may range from installation and deployment of servers to providing troubleshooting and technical support for projects.
If you’re reading to explore a career in system administration, you’ve come to the right place. In this article, we’ll define the sysadmin job, roles and responsibilities, and salary trends.
What is a sysadmin?
Short for “system administrator”, sysadmins are responsible for administration, management, and support activities associated with the IT infrastructure at a multi-user organization. Responsibilities within the domain of IT systems administration can be distributed across different job titles depending on size of the organization or the scope of work required. For instance, database administrator (DBA), security administrator, and network administrator may be distinct job roles at a large enterprise but accomplished by an individual sysadmin at an SMB organization.
End users frequently interact with sysadmins through support ticketing systems and sysadmins respond with appropriate changes and solutions while maintaining organizational policies for issue resolution.
Sysadmin role and responsibilities
The responsibilities of a sysadmin position typically include the following:
- User administration. The primary responsibility of a sysadmin is to support reliable and effective use of complex IT systems by end users, whether internal employees or external customers.

- System health monitoring. Most IT issues go unnoticed until the impact reaches end users. Sysadmins therefore monitor system health and identify anomalous network behavior, which may include security-sensitive activities such as unauthorized network access and data transfer. Advanced technology solutions may be used to accomplish these tasks, supporting the wider IT Security and Operations departments.
- Backup and disaster recovery. Sysadmins implement data backup and disaster recovery strategies for different IT systems and SDLC environments.
