What Is a Linux Kernel Developer and How to Become One

By ZipRecruiter Marketplace Research Team

A Linux kernel developer uses computer code to create a program that functions as the core of a computer operating system. Your duties can include creating kernels for open-source operating systems for desktop computers, laptops, phones, and tablets. You can also develop programs for embedded systems for routers, smart devices, or automated machinery. Linux uses C programming languages, so you often write code in C and C++. In addition to your coding responsibilities, you also test and debug your programs. Your employer may ask you to develop applications, drivers, and other tools to use with your kernel.

Linux kernel developers design and implement applications and drivers for devices, such as a cell phone or smartwatch. There are no formal education requirements to become a Linux kernel developer, though some employers prefer candidates with a bachelor’s degree in computer science or a related field. Practice using Linux, version control systems such as Git, and programming languages including C, or C++, and Python to become proficient in their uses. Or, acquire an entry-level position with a software company or in an IT department to gain experience working with different kinds of applications. Develop mock Linux kernels to build a portfolio, and seek positions with software companies that utilize Linux.
