A Kernel Development developer works on the core component of an operating system, known as the kernel. They write and maintain code that manages system resources such as memory, CPU, and disk space, ensuring efficient and secure operations. They handle device drivers, system calls, application interfaces, and other low-level functions. Their responsibilities also include diagnosing and fixing bugs, optimizing system performance, and integrating new hardware support. They need a deep understanding of computer architecture, data structures, algorithms, and programming languages like C/C++. They also need to collaborate effectively with other developers and understand the complex layers of an operating system.
