What will I do?

IT Systems Administrators keep a company’s technology running safely and well. They handle everything from server faults to network upgrades. Their work covers hardware, software, security, and records.

  • Troubleshooting and support: diagnose and fix server hardware and software faults, including workstations and network gear.
  • System monitoring: check and adjust network performance to keep all components running reliably.
  • Security management: enforce access controls, apply security patches, and support disaster recovery planning.
  • Backup and recovery: set up and maintain backup steps to protect data and allow quick recovery.
  • Documentation: write and update system records, operational steps, and configuration notes.
  • Capacity planning: check the current setup to spot future network needs and recommend improvements.

What skills do I need?

IT Systems Administrators need a blend of technical skills and people skills. On the technical side, they must know how to manage operating systems such as Windows, Linux, and Unix. They also need to know server hardware, networking, virtualisation tools, and cloud platforms. Strong skills in fixing issues and applying security measures are key day to day.

Communication skills matter too. Admins explain technical issues to non-technical staff and write clear system records. They work with IT colleagues, vendors, and managers to plan upgrades and solve problems. A proactive mindset helps, as good admins spot issues before they become outages.
