IT support specialist

What does an IT support specialist do?

An IT support specialist helps staff and customers fix problems with computers, phones, software and accounts.

The job sits in the IT team of a Singapore company, government agency, school or hospital. It also exists at managed service providers that support many client firms.

You answer tickets, set up devices, reset access and record each fix. Work follows service level agreements (SLAs), which set how fast a ticket must get a first reply and a resolution.

You deal with end users every day. You also work with network, security and cloud teams, software vendors and the service desk manager. Problems you cannot solve go up to those teams with clear notes.

What the work involves

• Pick up tickets from the helpdesk queue, rank them by urgency and reply to the user.
• Fix hardware and software faults on laptops, desktops, printers and mobile phones, in person or by remote session.
• Create accounts, reset passwords and set access rights in Microsoft 365 and other business systems.
• Set up new devices through endpoint management tools and install the approved software.
• Record each fix in the ticket, then escalate faults you cannot solve to the right team.
• Write short guides for common problems and spot faults that keep coming back.

   What a good answer covers

   • Checks the IP address and whether it is a valid DHCP lease or a self-assigned one.
