AI Impact on RPG Developer

Risk Level: 6/10 | Industry: Technology | Risk Category: moderate

Overview

RPG (Report Program Generator) developers maintain and extend business applications written in IBM's RPG programming language, primarily running on IBM i (formerly AS/400 and iSeries) platforms. These systems form the backbone of thousands of enterprises in banking, insurance, manufacturing, distribution, and retail, processing billions of transactions daily with exceptional reliability and performance. RPG has evolved significantly from its origins as a fixed-format report generation language to RPG IV and RPG Free-Format, which support modern programming paradigms including modular design, ILE (Integrated Language Environment) procedures, embedded SQL, and web service integration. The challenge facing RPG developers is the shrinking talent pool as experienced programmers retire, combined with growing pressure from organizations to modernize their IBM i applications. AI is beginning to impact RPG development through automated code analysis tools that can understand legacy RPG code, suggest modernization paths, and even translate RPG programs to modern languages like Java, Python, or C#. AI-powered code generation tools are learning RPG syntax and can assist with routine coding tasks, while AI-based testing tools can generate test cases for legacy RPG programs. However, the deep business logic embedded in decades-old RPG applications requires human expertise to understand, validate, and carefully modernize without disrupting critical business operations. Organizations increasingly need RPG developers who can bridge legacy systems with modern architectures through APIs, microservices, and cloud integration, making experienced RPG professionals valuable despite the language's niche status.

How AI Is Changing the RPG Developer Profession

The disruption risk for RPG Developer professionals is rated 6 out of 10, placing it in the moderate risk category. This assessment is based on the nature of tasks performed, the current state of AI technology relevant to the field, and the pace of adoption within the Technology industry. Understanding these dynamics is essential for RPG Developer professionals who want to stay ahead of changes and position themselves for long-term career success. The World Economic Forum projects that 23% of jobs globally will change significantly by 2027, with AI and automation driving the majority of workforce transformation across all sectors.

Tasks at Risk of Automation

These tasks represent the areas where AI technology is most likely to reduce or eliminate the need for human involvement. The timelines reflect current technology readiness and industry adoption rates. RPG Developer professionals should monitor these developments closely and proactively shift their focus toward tasks that require human judgment, creativity, and relationship management — areas that remain difficult for AI systems to replicate effectively.

Tasks That Remain Safe from AI

These tasks require uniquely human capabilities — judgment under ambiguity, emotional intelligence, creative problem-solving, physical dexterity, or complex stakeholder management — that current and near-future AI systems cannot perform reliably. RPG Developer professionals who deepen their expertise in these areas will find their value increasing as AI handles more routine work, freeing them to focus on higher-impact contributions that drive organizational success.

AI Tools Entering This Role

Familiarity with these tools is becoming increasingly important for RPG Developer professionals. Employers are looking for candidates who can work alongside AI systems to enhance productivity and deliver better outcomes. Adding specific AI tool proficiency to your resume signals to both applicant tracking systems and hiring managers that you are prepared for the evolving demands of the role.

Salary Impact Projection

RPG developer salaries are increasing 10-15% annually due to severe talent shortages, ranging $90,000-$160,000+. Senior RPG modernization architects earning $140,000-$200,000+ as enterprises prioritize legacy transformation. Contract rates for experienced RPG developers reaching $100-$175+/hour.

Salary trajectories for RPG Developer professionals are increasingly bifurcating based on AI adaptability. Those who develop AI-complementary skills and demonstrate the ability to leverage automation tools are seeing salary premiums of 15-30% compared to peers who have not invested in AI literacy. This trend is expected to accelerate through 2027 as more organizations complete their AI transformation initiatives and adjust compensation structures to reflect new skill requirements.

Adaptation Strategy for RPG Developer Professionals

Focus on becoming an RPG modernization specialist who bridges legacy IBM i systems with modern architectures. Learn RPG Free-Format and fully embrace modern RPG IV programming practices including modular ILE design, embedded SQL, and service program architecture. Develop expertise in exposing RPG business logic as RESTful APIs and web services, enabling legacy applications to participate in modern microservices architectures. Build skills in IBM i integration technologies including Node.js on IBM i, Python on IBM i, and open-source tools available on the PASE environment. Learn cloud integration patterns for connecting IBM i systems with AWS, Azure, and Google Cloud services. Understand DevOps practices adapted for IBM i, including source control with Git, CI/CD pipelines, and automated testing frameworks for RPG applications. Consider learning complementary languages like Python or JavaScript to build modern frontends and middleware that connect to RPG backends. Stay current with IBM i operating system updates and new platform capabilities that enhance RPG development productivity.

The key to thriving as a RPG Developer in the AI era is not to resist technology but to strategically position yourself at the intersection of human expertise and AI capabilities. Professionals who can demonstrate both deep domain knowledge and comfort with AI-powered tools will find themselves more valuable, not less. The Technology industry rewards those who evolve with the technology landscape while maintaining the human judgment, creativity, and relationship skills that AI cannot replicate. Building a portfolio of AI-augmented work examples provides concrete evidence of your adaptability when applying for new positions or seeking advancement.
