As a remote mainframe developer, you work from home to design, code, test, and configure software and applications used on a mainframe system. Mainframes are large computers with particularly high processing power and are often used for critical tasks like bulk data processing or enterprise resource planning. In this role, you may help ensure all new software is fully backward-compatible, monitor system performance, isolate errors, and work collaboratively with other developers as needed. Most mainframe developers work for larger companies. As a remote employee, you use virtual office software, phone, chat, or email to remain connected to other employees.

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

To thrive as a Remote Mainframe Developer, you need strong programming skills in languages like COBOL, JCL, and experience with mainframe operating systems, often supported by a degree in computer science or related field. Familiarity with tools such as IBM z/OS, DB2, CICS, and version control systems is typically required, along with relevant certifications. Excellent problem-solving abilities, independent work ethic, and effective virtual communication are standout soft skills for this remote role. These skills ensure smooth maintenance, modernization, and support of critical legacy systems in distributed teams.

How does a Remote Mainframe Developer typically collaborate with on-site teams and manage communication challenges?

As a Remote Mainframe Developer, you'll often work closely with on-site IT teams, business analysts, and project managers through virtual meetings, chat platforms, and shared documentation tools. Effective communication is key, so regular check-ins and proactive status updates help ensure alignment on project goals and troubleshooting efforts. Many companies use agile methodologies, which means you'll likely participate in daily stand-ups and sprint planning sessions remotely. While time zone differences can be a challenge, flexible scheduling and clear communication protocols are common strategies to keep everyone connected and productive.

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.
