What does a Linux kernel developer do?

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.
