System administrator salary

The system administrator role is one of the few IT careers that can be a junior, intermediate, or senior position. Education is important, but work experience is incredibly meaningful here—veteran sysadmins are tremendously valuable and are compensated accordingly.

According to Glassdoor, the average total median salary for a system administrator is $98,384 USD, with senior system administrator titles averaging $124,120 USD. The United States Bureau of Labor Statistics places the median pay for a system administrator slightly lower at $80,600 USD per year without any related work experience.

How to be a successful system administrator

According to the United States Bureau of Labor Statistics, demand for system administrator positions is projected to grow five percent between 2020 and 2030. Whether you are looking to start or grow your career as a system administrator, a few strategies can help candidates stand out from the rest of the job market.

Aspire to be a lifelong learner

Stay ahead of the curve by researching new technologies, even at a high level. Let your curiosity be the guide and absorb any and all training that is available.

Work on your communication skills

System administrators are often the first point of contact for users experiencing issues—and that user might just be the boss. Therefore, sysadmins should have exceptional interpersonal communication skills so they can resolve problems as quickly as possible.

Be confident and understanding

Don’t underestimate the impact of IT-related issues on your organization’s users. When they can’t do their jobs, it adds stress to their world, and they are often powerless to do anything about it. A skilled system administrator knows how to project confidence and reassure users that even if the solution isn’t immediately clear, it will be soon.

Investigate patterns

The best system administrators can recall past scenarios and issues to find patterns and relate one issue to a previous one. This solution-oriented mindset means they are always wondering how the current issue fits into the big picture.

Stay flexible

System administrators often need to wear many hats and change them throughout the day. In one moment they may be helping developers get the access they need, and in the next, they are answering data architects’ questions about roles and requirements. This flexibility is essential to effective system administration.

Related positions to consider

It is not uncommon for system administrators to be a catch-all title that can apply to several different specialties and roles. For those looking to specialize, or to focus on specific technologies, there are a few other roles to consider:

• Network administrator
