Is IBM still making mainframes?

IBM continues to manufacture mainframes, such as the IBM Z series, which are widely used in enterprise environments for their reliability, security, and scalability. Mainframes remain a key platform for large-scale data processing and transaction workloads, and many organizations rely on mainframe developers to maintain and upgrade these systems.

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.

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.

The role offers stable employment, competitive salaries, and opportunities to work with legacy technologies like COBOL and JCL. However, it requires specialized skills and ongoing learning to stay current with evolving systems and tools.

Can mainframe be replaced by AI?

Mainframe developers work with large-scale, legacy systems that require specialized knowledge of mainframe architectures, 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 maintain and optimize critical enterprise systems. AI tools may assist in development, but human expertise remains essential for complex mainframe environments.

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 the salary of a mainframe developer?

The salary of a mainframe developer typically ranges from $70,000 to $120,000 annually, depending on experience, location, and certifications.

We specialize in partnering with Home Builders as well as retail production. FCM funded $2.6 Billion in 2024 through affiliated business arrangements with 10 different home builders, 5 of which rank in the Top 65 Home Builders in the country. 

FCM is currently seeking an Application/AI Developer. This role will report to the CTO. 

About the Role

We are looking for a talented and motivated Developer to join our team. In this role, you will be at the intersection of application integration, artificial intelligence, and data engineering - building the systems and pipelines that power our business. You will also play an important part in shaping security policies for AI-driven applications and integrations.

Key Responsibilities
  • Design, develop, and maintain application integrations across internal and third-party platforms using modern API patterns (REST, GraphQL, webhooks).
  • Build, deploy, and manage AI agents and LLM-powered workflows to automate business processes and enhance decision-making.
  • Develop and implement AI-driven business workflow automation solutions, identifying opportunities to streamline operations and reduce manual effort across the organization.
  • Develop and maintain data integration pipelines, ensuring reliable data flow between systems, databases, and data warehouses.
  • Collaborate with stakeholders to define and implement information security policies and procedures specific to AI agents and AI-powered integrations.
  • Monitor, troubleshoot, and optimize existing integrations and AI solutions for performance and reliability.
  • Document technical designs, integration patterns, and security standards for team and organizational use.
Required Skills & Qualifications
  • Demonstrated experience developing AI agents, prompt engineering, and working with LLM frameworks (e.g., LangChain, LlamaIndex, OpenAI, Anthropic, or similar).
  • Proficiency in API development - designing, building, and consuming RESTful or GraphQL APIs.
  • Hands-on experience with data warehousing platforms (e.g., Snowflake, BigQuery, Redshift, or similar) and data integration best practices.
  • Experience developing software tools and integrations within the mortgage lending industry, with familiarity in lending workflows, loan origination systems (LOS), or related financial services platforms.
  • Ability to create and enforce security policies for application and AI development, including access control, data handling, and compliance considerations.
  • Solid understanding of software development best practices: version control (Git), testing, CI/CD pipelines.
  • Strong written and verbal communication skills; able to document technical work clearly for both technical and non-technical audiences.
Nice to Have
  • Experience with cloud platforms (AWS, Azure, or GCP) and managed integration services.
  • Familiarity with ETL/ELT tooling (dbt, Fivetran, Airbyte, or similar).
  • Background in compliance frameworks relevant to AI systems (SOC 2, NIST AI RMF, or similar).
  • Experience with workflow automation tools (n8n, Zapier, Make, or similar).
Work Arrangement

This is a primarily remote position. Candidates should expect occasional on-site visits for team collaboration, planning sessions, or project kick-offs. Travel frequency will be communicated during the interview process.
