Empower your technology with Linux expertise! Find top Linux developers for robust system solutions ensuring security, stability and high performance.

Developed by Linux Torvalds in 1991, Linux is an operating system similar to Windows or macOS. This means it provides services to applications while managing the computer hardware and acting as an interface between software and hardware. Although originally developed to act simply as an operating system, Linux is now an ideal platform for computer-savvy individuals to run desktops, servers, and embedded systems.

Thanks to its modular design, Linux offers many variations and distributions with a “Kernel” as its core. This Kernel helps schedule applications and processes, manages basic devices, oversees services related to file systems, and manages network access. Thanks to this customization capacity and the system's many advantages, almost all vertical companies currently use Linux in technologies ranging from supercomputers to intelligent products.

Developers specializing in Linux are typically the Swiss Army knives of the development community: they not only know how to use the programming languages needed to handle Linux itself, but also its applications. If you want to hire Linux developers here's what to look for.

Hiring Guide

Although macOS and Windows are the most common operating systems, Linux is constantly in demand in the professional world. In fact, it is one of the most sought after open source platforms by developers and companies. Its versatility, security, speed, and free public access as an open source operating system make it one of the most active developer communities.

Companies and individuals benefit greatly from using Linux. Most web servers actually use Linux or a Linux environment. It is very common as the core of a development environment, while also helping developers simulate real-world usage when testing applications. Linux acts as an excellent resource for testing code before deploying to a real production environment.

Part of what makes Linux a preferred choice for so many developers is its open source availability. Anyone can download the operating system's source code, modify it, and distribute the new version they created. With the code readily available to anyone who wants it, this means it is constantly peer-reviewed and scrutinized by a huge Linux expert online community.

As developers, those specializing in Linux offer many skills to companies in addition to knowing how to manage the operating system itself. Linux is an incredibly powerful and flexible platform, which means users can do much more with it than with other operating systems. This means that developers with Linux expertise are typically not only creative in their customizations, but also creative in making things work.

The creative mind of Linux developers also means they are curious by nature. They not only want to know how the platform works, but they also strive to gain a deeper understanding of its inner workings. Linux users typically understand that the operating system is more like a collection of parts that work together by design, which makes them not only better at understanding how hardware and software work together, but also forms the backbone of a great developer. .

Linux developers also have in-depth knowledge of installing applications from source, which means they are experts at viewing source code and understanding package layouts. By the nature of the operating system, Linux programmers also understand software dependencies at a much more detailed level than most. Typically, developers who specialize in Linux also have strong problem-solving skills, as Linux offers all the tools needed to solve problems.

Linux Interview Questions

What are the basic components of a Linux operating system?

Kernel – Most consider the Kernel to be the central aspect of a Linux operating system, as it is responsible for all the main activities of the system. Linux Kernel is free and open-source software that offers the ability to manage hardware resources to its users. It consists of modules that interact directly with the underlying hardware while the Kernel acts as the brain of the system.
System Library – System libraries implement most of the operating system's functionality. When application programs access Kernel resources, these libraries act as a special function.
System Utility – These programs perform specialized, individual-level tasks.

What are the main features of the Linux operating system?

The Linux kernel and applications are not restricted to any hardware platform, which means the operating system can be installed anywhere and considered portable.
It allows multitasking by serving many functions simultaneously.
The operating system provides a hierarchical file system.
It provides security in the forms of authorization, encryption, and authentication.
Supports proprietary apps and custom keyboards.
Linux supports multiple users accessing a system resource through different operating terminals.

What is LILO and what kind of advantages does it offer?

LILO is the abbreviated term for Linux Loader, which is the boot loader of the operating system to fully load it into main memory to begin operations. LILO resides inside the Master Boot Record (MBR) and the bootloader manages a dual boot. LILO helps developers quickly boot Linux after MBR installation. However, not all computers have the ability to tolerate modifications to the MBR.
