What is a mainframe data engineer?

Mainframe data engineers are IT professionals who specialize in managing, maintaining, and optimizing data systems on mainframe computers. They develop and support data pipelines, databases, and storage solutions, ensuring the efficient processing and integrity of large-scale enterprise data. Their work often involves programming in languages like COBOL, SQL, and working with technologies such as IBM z/OS and DB2. Mainframe data engineers play a critical role in industries like banking, insurance, and government, where mainframes are still widely used for high-volume transaction processing.
