Systems administrators are essential to most companies. So you could probably find a job almost anywhere. Which is great, especially if you're looking for a career with a lot of job opportunities. Of course, who's going to realistically turn down opportunity?
As a systems administrator, it's on your shoulders to keep the company servers up and working smoothly. Of course, there will be crashes you'll have to deal with. After all, that's why you're there in the first place.
When an employer looks for a systems administrator, they're usually looking for an individual who has a bachelor's degree. But that's not all. This isn't an entry-level position so you're going to need at least 3-5 years of experience under your belt as well. Once you get all of those checked off, you'll be well on your way to your dream career.
