An Active Directory developer designs, develops, and manages the infrastructure of Windows Server Active Directory (AD). They primarily focus on the creation and maintenance of domains, users, and objects within a network. They create group policies, manage user access, and ensure network security. They also troubleshoot any issues related to AD and optimize its performance. These developers also work on integrating AD with other applications and platforms. They may also be involved in migration or upgrade projects for Active Directory. Understanding of scripting languages, such as PowerShell, for automating tasks is often required.
