What does a Mainframe Developer do?
Mainframe development is a little different from the usual web development roles many freshers see.
Instead of mainly building websites or mobile applications, you will work with large enterprise systems that handle important business processes. These systems are still widely used in areas such as banking, insurance, retail and other large organisations.
As a Mainframe Developer at Infosys, the work can include understanding requirements, writing and maintaining code, testing applications, finding bugs and helping resolve application issues.
You may also work with different development and support teams when an application needs troubleshooting or changes.
Mainframe Technologies You Should Know
The Infosys Mainframe Developer Hiring 2026 role specifically mentions the following technologies:
COBOL
PL/1
CICS
JCL
DB2
Among these, COBOL, JCL, CICS and DB2 are particularly important areas to prepare if you are targeting mainframe development.
If you are a fresher and have studied these technologies during college or through a course, make sure they are clearly mentioned in your resume.
IBM Tools Mentioned in the Role
The listing also refers to IBM development and collaboration tools, including:
IBM Rational Developer for z Systems (RDz)
IBM Developer for z Systems (IDz)
Rational Business Developer (RBD)
Rational Team Concert (RTC)
You do not need to add a technology to your resume just because you have heard its name. If you have actually used any of these tools in a project, training or internship, mention that experience clearly.
Other Skills That Can Help
Mainframe knowledge is the main technical area, but the role also expects a basic understanding of software development concepts.
You should be familiar with:
Object-oriented programming concepts
Software design principles
Design and architectural patterns
Software Development Life Cycle
Database concepts
Database schema design
Unit testing
Automated testing
Troubleshooting
Technical documentation
Agile methodologies
Good communication is also useful because the role involves working with teams across different locations.
What will you work on?
The day-to-day work can vary depending on the project you are assigned to, but the role includes activities such as:
Understanding business and user requirements
Developing mainframe applications
Maintaining existing applications
Writing efficient and reusable code
Testing application changes
Finding and fixing bugs
Troubleshooting development and production issues
Looking at different technical solutions
Supporting application design and development
Working with databases
Creating or updating database schemas
Working across different environments
Taking part in technical discussions
Preparing technical documentation
Working with distributed or remote teams
This means the job is not only about writing COBOL code. You also need to understand how an application works, how data moves through the system and how to identify problems when something goes wrong.
Is Infosys Mainframe Developer Hiring 2026 suitable for freshers?
Yes. The listing mentions 0-4 years of experience, so freshers fall within the stated experience range.
However, if you are applying as a fresher, having some practical knowledge of mainframe technologies can make your profile much stronger.
For example, if you have created a small COBOL project and connected it with DB2, do not simply write “COBOL” under your skills. Mention what you actually built.
Even a basic project can give you something useful to discuss during an interview.
A Simple Project You Can Build
If you want to prepare specifically for the Infosys Mainframe Developer Hiring 2026 role, try building a small Bank Account Management System.
You could use:
COBOL for the main program
DB2 for storing customer and account information
JCL for batch processing
The project could support basic operations such as:
Creating an account
Checking account details
Depositing money
Withdrawing money
Generating a simple transaction report
While building it, try to understand why each technology is being used. That is more useful than simply memorising definitions.
How to Prepare for the Infosys Mainframe Developer Hiring 2026 Role
If you are a fresher, start with the basics and build from there.
1. Learn COBOL fundamentals
Focus on:
Program structure
Variables and data types
Conditions
Loops
Files
Sequential processing
Procedures
Error handling
2. Understand JCL
Learn how JCL is used to run jobs on a mainframe system.
Understand concepts such as jobs, steps, datasets and basic job execution.
3. Learn DB2 and SQL
Practice basic SQL operations such as:
SELECT
INSERT
UPDATE
DELETE
JOIN
GROUP BY
Also understand how applications interact with databases.
4. Study CICS basics
You should know what CICS is used for and how it supports transaction processing.
5. Practice troubleshooting
Do not only learn how to write code. Try to understand how you would find the reason when a program or job fails.
6. Learn SDLC and testing
Be comfortable with basic software development and testing concepts, including unit testing and application validation.
Resume Tips
For the Infosys Mainframe Developer Hiring 2026, your resume should make your relevant technical skills easy to find.
A fresher can highlight:
COBOL
JCL
DB2
CICS
SQL
Mainframe concepts
Relevant academic projects
Mainframe certifications or training
Internships
Problem-solving skills
If you have completed a mainframe project, give it a separate project section instead of hiding it under a general list of skills.

Is Mainframe Still Worth Learning?
If you are wondering whether mainframe technology is still relevant, the answer is yes.
Large organisations continue to depend on mainframe systems for important business operations. Mainframe development also remains a specialised area, which means candidates with the right technical knowledge can build a career in this space.
There is also increasing interest in modernising older enterprise systems. This makes it useful to understand both traditional technologies such as COBOL and newer software development practices.
Recent industry reporting has also highlighted the continued importance of COBOL and mainframe systems in large enterprise environments, including banking and other critical business applications.

Mainframe application development
COBOL
JCL
CICS
DB2
Application maintenance
Enterprise software systems
Testing and troubleshooting
Agile development practices
Working with large technology teams
It can also help you develop a specialised technical skill set instead of following the same path as every other fresher applying for general software developer roles.
Final Takeaway
The Infosys Mainframe Developer Hiring 2026 opportunity is suitable for candidates with 0-4 years of experience, including freshers who have relevant mainframe knowledge.
The most important technologies to focus on are COBOL, JCL, CICS and DB2. Along with these, understanding SQL, testing, SDLC and troubleshooting will help you become better prepared for the role.
