The job of a System Administrator is to assume a range of IT responsibilities and technical services for your company’s internet and intranet presence. This will include such duties as installing anti-virus and malware protection software, undertaking regular systems maintenance, and troubleshooting problems. Additional duties can include serving as a digital technology information resource for employees and consulting with company leaders on the possible adoption of new technologies. Aside from this, you might be asked to evaluate and boost network system performance, make needed upgrades and repairs, and add approved users to the network and train them in proper usage.

To thrive as a System Administrator, you need a solid understanding of computer networks, operating systems (Windows, Linux), and troubleshooting, often backed by a degree in IT or related certifications like CompTIA Network+ or Microsoft Certified: Azure Administrator Associate. Familiarity with tools such as Active Directory, virtualization platforms, backup solutions, and monitoring systems is typically required.
