The 10 Essential Skills for Mainframe Developers in 2024

In an increasingly digital world, mainframe systems continue to play a crucial role in many organizations. Despite their longevity, these systems require highly skilled professionals for their maintenance and development. This article explores the most in-demand skills in the field of mainframe development, offering a valuable guide for those looking to thrive in this specialized technological area.

The resurgence of a classic technology
Mainframes, despite being considered by some as technology of the past, continue to be the backbone of data operations for numerous large-scale companies. Their ability to process massive volumes of information at high speeds makes them indispensable in sectors such as banking, insurance, and government.

Fundamental technical skills
1. Mastery of specific programming languages
Mainframe developers must be experts in languages like COBOL, PL/I, and Assembler. Although they may seem outdated, these languages remain vital for many critical systems.

2. Knowledge of CICS (Customer Information Control System)
CICS is a crucial transaction manager in mainframe environments. Developers must understand how to create and maintain applications that use this system.

Database management is essential, and DB2 is the predominant system in mainframes. Developers must be able to design, implement, and optimize DB2 databases.

4. Experience with JCL (Job Control Language)
JCL is essential for job execution on a mainframe. Developers must be able to write and debug efficient JCL scripts.

Soft skills and supplementary knowledge
5. Analytical ability
Solving complex problems and optimizing systems require strong analytical skills.

6. Effective communication
Mainframe developers often have to explain technical concepts to non-technical teams, so clear communication is crucial.

7. Adaptability and continuous learning
Technology is constantly evolving, even in the mainframe world. Professionals must be willing to learn and adapt.

8. Digital security knowledge
With the rise of cyber threats, security has become a priority. Developers must understand and implement robust security practices.

Emerging trends
