Linux Systems Engineer cover

Unlike Windows or macOS, Linux is an open-source operating system that is free and accessible to all. That is, any user can run, modify, and share Linux code. Its open-source nature is a big advantage over traditional operating systems which are locked down, proprietary, and unmodifiable. Linux also has the advantage of being more secure and having fewer security holes than traditional systems.

More and more, large companies are using computers running Linux. Accordingly, the Linux System Engineer function is on the rise. The Linux System Engineer is an essential link within companies that ensures the proper functioning of a Linux network. The engineer helps coordinate the IT team, optimises network operations and ensures communication between the various information systems.

What is the role of the Linux Systems Engineer?

The missions of a Linux Systems Engineer revolve around two main areas:

“Build” project activities

The Linux Systems Engineer is primarily in charge of what are called project or “build” activities. That is to say everything related to technical advice, expertise and innovation. The role of the Linux systems engineer is to advise CIOs on the use and configuration of technical solutions in Linux.

This professional is also responsible for supporting the implementation of new solutions under this operating system. They also contribute to the technical validation phase and must implement means to guarantee the high quality and availability of the service. This professional must also keep an eye on all new developments regarding Linux to optimise system resources and continuously improve the operating system.

“Run” production activities

The Linux System Engineer is also responsible for intervening in production activities, which is called the “run.” That is to say the maintenance of the operating system, administrating it and maintaining it operational. The engineer must ensure that the entire system is functional and usable. They must also take care of the day-to-day administration as well as measure and optimise system performance. They provide preventive, corrective and evolutionary maintenance of the Linux systems of the company. They are also responsible for managing incidents by ensuring the diagnosis and repair of any malfunctions. The Linux Systems Engineer is also responsible for testing the system, ensuring its security and reliability, and managing the user support side of things.

Linux Systems E can specialise in either project activities or in production activities, but, generally, these professionals are involved in both types of activities. A good Linux Systems engineer will be able to work on both project and production activities.

Required skills

Very good technical mastery

The Linux Systems Engineer should have very good knowledge of the Linux operating system and expertise in technical infrastructure software. They must have an in-depth knowledge of Linux system layers as well as a good knowledge of Linux installation processes. They must also often master programming languages, including Python, and also know Scripting (Patch or PowerShell). The Linux Systems Engineer should also have good knowledge of databases and security standards.

Solid professional skills

The Linux Systems Engineer must be rigorous, organised and methodical, as their missions require compliance with quality processes and rules. They must have great capacity for anticipation, initiative, technical curiosity and adaptability to ensure effective technical monitoring and adapt quickly to new technological developments. It is also important that this professional has good analytical skills, resistance to stress and reactivity so they can deal with breakdowns or technical incidents. They also need to be versatile and have good interpersonal skills to maintain good relationships with other stakeholders.


The average daily rate a Linux Systems Engineer ranges between €200 and €600. Their median salary sits between 30K and 60K per year.


To become a Linux Systems Engineer a university-level degree is required. That is to say, you generally need to have an engineering degree or a master’s degree specializing in computer science.

Several universities offer specialisations in operating systems, and engineering schools often offer specialties at the end of the course or have specialized courses. You can also take a Masters in computer science specialising in networks and systems or an engineering degree specialising in computer science.
