How to Write a System Administrator Resume

Here’s how to write a system administrator resume of your own.

Write Compelling Bullet Points

When you’re writing bullet points, it can be tempting to focus on the tasks and responsibilities of your job. But if you want to stand out from other candidates, you need to go beyond that and focus on the results of your work.

For example, rather than saying you “managed server infrastructure,” you could say that you “reduced server downtime by 50% through proactive monitoring and maintenance of infrastructure.”

The second bullet point is more specific and provides more detail about what exactly you did and the results of your work.

If your resume doesn’t include enough of the right keywords, the ATS might disqualify you from further consideration.

The best way to identify the right keywords is to read through a few of the job postings and take note of the terms that keep popping up. Then, try to use them throughout your resume. Here are some commonly used system administrator keywords:

  • Windows Server
