A CORBA (Common Object Request Broker Architecture) developer designs and implements software systems using the CORBA framework. This involves writing code in languages like Java or C++, defining system interfaces using IDL (Interface Definition Language), and integrating these interfaces with the CORBA middleware to facilitate communication between objects in a network. They also debug and maintain existing systems, ensuring the smooth operation of distributed applications. Additionally, they handle issues of system interoperability, scalability, and security. They often collaborate with other developers and stakeholders to understand requirements, troubleshoot issues, and deliver robust, efficient solutions.
