- Problem-solving. When technical problems arise within computer systems or networks, a system or network administrator is tasked with troubleshooting the issue and resolving the problem.
- Automation. The ability to implement automated solutions, where tools and software can be administered in a self-service way to a host of constituents, is a key skill systems administrators should possess.
- Security and monitoring. Because computer networks can be vulnerable to malicious attacks, inside and outside the organization, the systems administrator should not only protect the network from vulnerabilities but also repair any damage caused by those attacks.
- IoT and mobile device management. Systems administrators should be familiar with setting up and maintaining an IoT (Internet of Things) environment, where an organization’s workforce can use mobile and other devices to leverage cloud platforms in the office or in the field.

- Software management. In addition to managing hardware, systems administrators must also install, troubleshoot, and maintain software the organization relies on to conduct business.
- Cloud computing. A systems administrator should be well versed in overseeing a company’s cloud computing environment, adding or removing software and data.
What are the core freelance systems administrator job responsibilities?
Although the size of the organization will dictate the specific responsibilities, a freelance systems administrator will generally be responsible for the following:
- Installing and maintaining of hardware and software
- Managing data centers within a network and in the cloud
- Managing security and protocols through permissions, updates, patches, and troubleshooting
- Monitoring computer systems in order to identify potential trouble areas
- Resolving problems when issues arise
- Establishing and managing backup procedures
- Training staff and other constituents regarding the use of new software, technologies, and hardware
- Providing support, as needed, to key constituents
Should I get a systems administrator certification?
In addition to developing your skills, obtaining a professional certification can help your Upwork profile stand out. Some examples of popular systems administrator certifications include:
- MCSE: Productivity Solutions Expert. Cloud computing is a $150 billion industry. As a result, MCSE certification can prove valuable for anyone looking to expand their understanding of cloud and IT-related environments.
