What is a windows device driver?

A Windows Device Driver job involves developing, debugging, and maintaining low-level software that allows hardware devices to communicate with the Windows operating system. Engineers in this role work with kernel-mode and user-mode drivers, ensuring compatibility, stability, and performance. They often use programming languages like C and C++ and work with tools such as Windows Driver Kit (WDK) and WinDbg for debugging. This role requires a strong understanding of operating system internals, hardware interfaces, and memory management.
