Job description
Much of the job is proactive monitoring: checking that servers, backups, and scheduled jobs actually completed, reviewing logs for anything unusual, and tracking how much load the network and servers are under so problems get caught before users notice. When something breaks, administrators diagnose the issue, manage user access and software licenses, and keep antivirus and email systems current. It's largely desk-based work with steady, moderate deadline pressure that calls for independent judgment rather than close supervision. The number of these roles has been declining somewhat as cloud services take over tasks once handled in-house, though it remains a common entry point into broader IT careers.
Pros
- High upside earning potential, up to $155k
- Standard indoor desk work with a consistent 40-45 hour week
- Broad, technical role spanning networks, servers, security, and backups rather than one narrow task
Cons
- Employment in this field is projected to shrink over the next decade (-4.2%), partly from cloud consolidation
- Requires a bachelor's degree, a longer educational path than many entry-level IT roles
- On-call responsibility for outages and disaster recovery can intrude on personal time
A typical day
The morning starts in the ticket queue: overnight monitoring flagged a server with a failing disk, so the first hour is swapping the drive and watching the RAID array rebuild while triaging password resets and a VPN issue. Mid-morning is project work — building out a new file server, testing group policy changes in a sandbox before they touch production. At 1pm a department's shared drive goes unreachable and the admin drops everything, tracing the outage to a switch that needs a reboot and a replacement on order. The afternoon closes with patch planning for the monthly maintenance window, verifying last night's backups actually restore — the check most people skip until it matters — and documenting the day's changes so future-them can retrace today's decisions.
Tasks at the job
- Maintain and administer computer networks and related computing environments, including computer hardware, systems software, applications software, and all configurations.
- Perform data backups and disaster recovery operations.
- Diagnose, troubleshoot, and resolve hardware, software, or other network and system problems, and replace defective components when necessary.
- Configure, monitor, and maintain email applications or virus protection software.
- Operate master consoles to monitor the performance of computer systems and networks and to coordinate computer network access and use.
- Monitor network performance to determine whether adjustments are needed and where changes will be needed in the future.
Workplace & working conditions
Work happens indoors in a climate-controlled setting, and most of the day is spent sitting at a desk.
There's a regular, moderate amount of time pressure, and you're expected to exercise significant independent judgment day to day.
