About The Position

Do you want to work for a company where the people are the purpose? At Grimco, our developers aren’t just maintaining a system — they’re building and modernizing a platform that runs the daily operations of one of North America’s leading sign supply distributors. As an IBM i Developer, you’ll have direct ownership of meaningful work on a mission-critical platform, with the support and mentorship to grow your skills alongside it.

Requirements

• 3–5 years of development experience on IBM i (AS/400 / iSeries / Power Systems).
• Demonstrated proficiency in fully free-format RPG IV.
• Strong understanding of ILE concepts: modules, service programs, binding directories, and activation groups.
• Embedded SQL and DB2 for i — SQL-based I/O is the standard here, not the exception.
• CL / CLLE for job control and batch processing.
• Familiarity with prototype keywords, data structures, and modern procedure-based program design.
• Ability to read, understand, and modernize legacy fixed-format code when needed — without writing new fixed-format code.
• Experience with RDi or VS Code + Code4i extension for development.
• Candidates must be authorized to work in the United States. Grimco does not provide employment visa sponsorship (e.g., H-1B, O-1, TN) and will not do so in the future for this position.

Nice To Haves

• COMMON Certified Application Developer — ILE RPG on IBM i, or active pursuit of it.

Responsibilities

• Develop new business applications and maintain existing ones using fully free-format ILE RPG (RPGLE / SQLRPGLE) and CL.
• Write efficient embedded SQL against a DB2 database to support data retrieval, processing, and reporting.
• Build and maintain modular ILE objects — modules, service programs, and binding directories.
• Collaborate with project managers, QA, and business stakeholders to translate requirements into clean, well-documented code.
• Participate in code reviews, debugging, root cause analysis, and production support.
• Work within a structured development workflow using Jira and contribute to deployment processes.
