A typical day for an AS400 Developer involves writing, testing, and troubleshooting code in RPG, COBOL, or CL for business-critical applications running on IBM iSeries systems. Developers often work closely with business analysts, system administrators, and other IT professionals to gather requirements, implement system enhancements, and ensure data integrity within DB2 databases. Daily tasks may also include resolving production issues, performing regular maintenance, and participating in code reviews or deployment planning. Collaborative work and clear communication are common, as developers typically play an integral role in supporting both legacy and modernized business processes.
To thrive as an AS400 Developer, you need strong skills in RPG, COBOL, or CL programming languages, knowledge of IBM iSeries/AS400 systems, and typically a degree in computer science or related field. Familiarity with DB2 databases, SQL, and tools like Turnover or Aldon for change management and version control is highly valued, and certifications in IBM technologies are beneficial. Strong problem-solving abilities, attention to detail, and effective communication help developers collaborate with cross-functional teams and resolve technical issues efficiently. These competencies ensure reliable business application support, seamless integration with enterprise systems, and success in maintaining legacy environments.
