What Does a Remote Mainframe Developer Do?

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.

How much do mainframe programmers make?

Mainframe programmers typically earn between $70,000 and $120,000 annually, depending on experience, location, and certifications. Senior roles or those with specialized skills in COBOL, JCL, or mainframe tools can command higher salaries, especially in industries like finance and government. Remote positions may also influence compensation levels.

Is mainframe still in demand?

Mainframe developers are still in demand due to the continued reliance of many large organizations on legacy systems for critical operations. Skills in COBOL, JCL, and mainframe environments remain valuable, especially in finance, insurance, and government sectors where mainframes handle high-volume transactions.

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.

Can mainframe be replaced by AI?

Mainframe developers work with large-scale, legacy systems that require specialized knowledge of mainframe environments, programming languages, and security protocols. While AI can automate certain tasks like code analysis and testing, it is unlikely to fully replace the need for skilled mainframe developers who manage complex, mission-critical systems. Instead, AI tools are increasingly used to augment their work and improve efficiency.

Does mainframe need coding?

Yes, mainframe developers typically need coding skills in languages such as COBOL, PL/I, or Assembler to create, maintain, and update mainframe applications. Proficiency in these languages is essential for working effectively in mainframe environments and often includes understanding of tools like JCL and DB2. Coding is a core part of mainframe development roles.

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.

What is a Remote Mainframe Developer?

A Remote Mainframe Developer is a software professional who specializes in designing, developing, maintaining, and troubleshooting applications that run on mainframe computers, while working from a remote location. Mainframes are powerful computers often used by large organizations for critical applications, such as transaction processing and bulk data handling. Remote Mainframe Developers use programming languages like COBOL, JCL, and Assembler, and often connect to mainframe systems via secure networks. Their work ensures that legacy systems remain efficient, secure, and up-to-date. This role typically requires strong technical skills, experience with mainframe environments, and effective communication for collaborating with on-site teams.

Job description

About the Role

We’re hiring a developer with deep, hands-on experience building with MCP and ChatGPT Apps. This is not a general AI role. You should already be comfortable working inside these ecosystems, even if that experience comes from building, testing, or experimenting with your own projects. This is a remote or in-person role (Austin, TX).

You’ll be responsible for creating production-grade AI applications, iterating quickly, and pushing the boundaries of what MCP and ChatGPT Apps can do.

What You’ll Do
  • Build, deploy, and maintain MCP-based applications
  • Develop and optimize ChatGPT Apps using tools, structured outputs, and workflows
  • Design AI-native product experiences from the ground up
  • Rapidly prototype and test new ideas using MCP and ChatGPT environments
  • Use Claude Code as part of your development workflow
  • Improve performance, reliability, and usability of AI-driven features
  • Collaborate on product direction and technical architecture
What We’re Looking For
  • Someone who has already spent serious time inside MCP + ChatGPT App environments
  • Builders who experiment, ship quickly, and learn by doing
  • Developers who understand both the technical and product side of AI apps
  • People who can operate with high ownership and minimal oversight

Requirements

  • Extensive experience working with MCP Apps and ChatGPT Apps
    • This can include production work, side projects, or heavy experimentation
    • You should not be learning these for the first time in this role
  • Strong proficiency in JavaScript (React) or TypeScript (Node.js preferred)
  • Experience integrating and working with LLM APIs (OpenAI, Anthropic, etc.)
  • Working knowledge of Claude Code and how to use it effectively in development workflows
  • Experience building and shipping full-stack applications
  • Strong understanding of prompt design, tool usage, and AI interaction patterns

Benefits

  • Retirement Plan (401k, IRA)
  • Paid Time Off (Vacation, Sick & Public Holidays)
  • Free Food & Snacks
  • Wellness Resources
  • Stock Option Plan
