To thrive as an Entry Level COBOL Developer, you need foundational programming knowledge, especially in COBOL, and typically a degree in computer science or a related field. Familiarity with mainframe systems like IBM z/OS and tools such as JCL, CICS, and DB2, along with any relevant certifications, is beneficial. Strong analytical thinking, attention to detail, and effective communication help you understand legacy codebases and collaborate with senior developers. These skills are crucial to maintaining critical business systems, troubleshooting issues, and supporting ongoing technology needs in industries that rely on COBOL.
