What are the key skills and qualifications needed to thrive as a Mainframe Programmer, and why are they important?

To thrive as a Mainframe Programmer, you need a solid understanding of COBOL, JCL, DB2, and general mainframe architecture, often supported by a degree in computer science or related experience. Familiarity with tools like IBM z/OS, TSO/ISPF, and source control systems such as Endevor or Changeman is typically required. Strong problem-solving skills, attention to detail, and effective communication set top performers apart in this role. These abilities are critical for maintaining legacy systems, ensuring data integrity, and supporting business-critical operations in large organizations.

What are some common challenges Mainframe Programmers face when working on legacy systems?

Mainframe Programmers often encounter challenges such as understanding complex, decades-old codebases written in languages like COBOL or Assembler, and integrating these systems with modern technologies. Documentation may be sparse or outdated, requiring strong problem-solving and analytical skills to decipher business logic. Additionally, coordinating with cross-functional teams—including business analysts, testers, and infrastructure specialists—is essential to ensure smooth system updates and migrations. Adaptability and effective communication are key to overcoming these obstacles and supporting mission-critical applications.

What are Mainframe Programmers?

Mainframe Programmers are specialized software developers who design, write, test, and maintain code for mainframe computer systems. These professionals primarily work with legacy programming languages such as COBOL, JCL, and sometimes Assembler, to ensure critical business applications run smoothly and securely. They are often employed in industries like banking, insurance, and government where mainframe systems remain essential for processing large volumes of transactions. Mainframe Programmers also troubleshoot system issues, optimize performance, and may assist in system upgrades or migrations.

What is the difference between Mainframe Programmer vs Mainframe Developer?

AspectMainframe ProgrammerMainframe Developer
Primary RoleWriting, testing, and maintaining mainframe codeDesigning and developing mainframe applications and systems
Skills & CertificationsCOBOL, JCL, DB2, certifications in mainframe technologiesSimilar skills, often with additional focus on system design and architecture
Work EnvironmentMainframe environments in banking, finance, governmentSame environments, with broader development responsibilities
Job FocusCode implementation and troubleshootingApplication development and system integration

While both roles work within mainframe environments and share skills like COBOL and JCL, Mainframe Programmers primarily focus on coding and maintenance, whereas Mainframe Developers are involved in designing and developing new applications and systems. The roles often overlap, but the developer role typically encompasses a broader scope in application lifecycle management.

What Does a Mainframe Programmer Do?

As a mainframe programmer, your job is to design and program applications for mainframe computers, which are powerful machines that help to run many commercial and industrial processes. In this role, you may conduct an analysis of existing software to ensure it is as error-free as possible, help test new software, and implement software in a way that makes it easy for users to access. Mainframe programmers often use coding languages like COBOL, C++, SQL, Java, and CLIST when programming software. Somewhat unusually, most companies prefer to stick with specific coding languages even when they are not necessarily the best language for the job in order to reduce complexity and the risk of errors.

Job description

Our Company
At Teradata, we believe that people thrive when empowered with better information. Teradata Autonomous Knowledge Platform activates enterprise intelligence by unifying data, knowledge and business context to achieve tangible outcomes. With Teradata, organizations can provide agents with full context for impact when it matters. Our solution lets businesses connect and scale on premises, in the cloud, or through a hybrid approach. Teradata delivers real business value with AI.
What You'll Do
Teradata is looking for a skilled Mainframe Developer to join our Customer Developer Tools (CDT) organization. This role is critical in supporting and evolving our mainframe-based connectivity solutions, ensuring reliability, performance, and seamless integration with Teradata Cloud systems.
Key Responsibilities
  • Build, maintain, and support Teradata mainframe connectivity solutions and utilities
  • Diagnose and resolve complex customer issues, including APAR development and SMP/E packaging and maintenance
  • Analyze and synthesize customer mainframe environments to reproduce and troubleshoot issues in lab environments
  • Profile system, network, and application performance using tools such as SDSF and SMF
  • Collect, analyze, and debug system dumps using IPCS and related tools (e.g., XDC)
  • Understand and work within mainframe security frameworks including RACF, Top Secret, and ACF2
  • Develop and maintain JCL and REXX scripts for build automation, testing, and performance validation
  • Read, understand, and maintain shared assembly code across multiple products
  • Collaborate with cross-functional teams, including architects, product managers, and support engineers

Specialized Responsibilities (Legacy / Transitional Systems)
While Teradata continues to modernize its platform, this role may include work on highly specialized legacy systems:
  • Contribute to and maintain a large-scale assembly-based codebase (TDP) requiring advanced debugging and system-level understanding
  • Support integration with CICS and IMS transaction environments
  • Assist in ensuring stability and backward compatibility as legacy systems are phased out

Who You'll Work With
You will work closely with engineering, support, and customer teams to diagnose complex issues, enhance existing systems, and contribute to modernization efforts as legacy components transition over time.
What Makes You a Qualified Candidate
  • 8-10 years of experience in IBM z/OS mainframe environments
  • Hands-on experience with SMP/E, APAR creation, and maintenance workflows
  • Proficiency in JCL and REXX scripting
  • Experience with dump analysis and debugging tools such as IPCS
  • Familiarity with performance monitoring tools (SMF, SDSF)
  • Solid understanding of mainframe security models (RACF, Top Secret, ACF2)
  • Ability to troubleshoot complex distributed and mainframe-integrated systems
  • Strong analytical and problem-solving skills

What You'll Bring
  • Experience with C and C++ is a strong plus
  • Exposure to mainframe assembly language (ability to read and understand required; deep expertise is a plus)
  • Experience with CICS and IMS integration
  • Familiarity with database connectivity systems or the Teradata ecosystem
  • Experience working in hybrid environments involving mainframe and cloud systems

Why We Think You'll Love Teradata
We prioritize a people-first culture because we know our people are at the very heart of our success. We embrace a flexible work model because we trust our people to make decisions about how, when, and where they work. We focus on well-being because we care about our people and their ability to thrive both personally and professionally. We are committed to actively working to foster an inclusive environment that celebrates people for all of who they are.
