What does a Senior Systems Administrator do?

Systems administrators are responsible for the setup and maintenance of a company or organization’s computer systems. They ensure a computer within a company's network, and especially the server, is operating smoothly and securely. Systems administrators configure and maintain a network computer system that includes hardware system software and applications.

Systems administrators ensure data is securely stored and perform regular backups of the data and information. They diagnose and resolve any hardware, software, networking, or system issues that arise and replace and upgrade any defective or outdated components if appropriate. They monitor systems’ performance to ensure they are functioning smoothly and securely and research and recommend new approaches to improve the network computer system if requested. They provide technical support to employees and personnel, and document the processes employees need to follow to work within a computing system. Systems administrators need relevant degrees, including a bachelor's degree in computer science or a relevant field, a diploma in information systems or information technology, and familiarity with SQL and database operations.
