10 Essential Skills for Novice, Junior and Senior SysAdmins

SysAdmin evolution

As the world evolves for systems administrators, “Linux is exploding with new ideas and it's a little scary …,” as commenter Mike Tarkowski put it.

Keeping up with emerging technologies in cloud computing such as OpenStack will be key to navigating this changing landscape, according to Randy Russell, director of certification for Red Hat.

Over the last year, the continuing rise of open cloud platforms and the increasing need for support for open source security projects have created even more demand for pros with special expertise in that area. Fifty-one percent of surveyed hiring managers say knowledge of OpenStack and CloudStack has a big impact on open source hiring decisions, according to the 2016 Linux Foundation/Dice Open Source Jobs Report. The skills they’re most aggressively seeking include DevOps, 58 percent, systems administration, 48 percent; and network administration, 32 percent.

Along with new skills, there are some core skills employers are looking for. Employers recruiting on college campuses ranked leadership and the ability to work as a team as their two most-sought-after traits, according to Job Outlook 2015 survey by the National Association of Colleges and Employers. But they’re also looking for strong communication skills, problem-solving skills, a strong work ethic and analytical/quantitative skills.

At every level, they seek three core skills: the ability to work with others; the ability to listen to directions and to troubleshoot problems; and the ability to communicate, both verbally (in person and on the phone) and in writing.

Beyond that, here are 10 essentials at each level in the evolution of systems administrators, gleaned from The Linux Foundation, LISA’s list, job descriptions and sources such as analyst Victor Janulaitis at Janco Associates.
