Unix System Administrator

3 Month Contract


£600 p/d Inside

A systems administrator at the most basic level is responsible for the installation, maintenance, configuration, and reliability of computer and operating systems - particularly in multi-user and networked environments. A systems administrator is expected to be a SME in a wide range of subjects, the most important of which are Operating Systems, Networking, Databases, Security, Computer Hardware, and Systems Reliability. A Systems Administrator must ensure reliable consistent uptime, performance, security, and resource usage on the systems they manage.

As a career discipline systems administration began with the creation of multi-user/timeshared computer systems in the 1950s and while the functions and skill sets required of the systems administrator have evolved considerably since that time the core skill of Problem Solving has remained central to the role.

Skill Sets:

These are divided into required skill sets and desirable skill sets. The required skill sets are those we have previously used to select candidates for interview in The Cloud WiFi while the desired skill sets are those we have found most useful in carrying out projects and interacting with colleagues in other team. We are limiting ourselves to technical skill sets. Where possible we prefer knowledge of a range of software or packages used for different protocols and functions rather than knowledge of particular packages, e.g. Git rather than Gitlab, SMTP rather than Sendmail.
