Role Summary

We are seeking a highly skilled and forward-thinking RPG Developer / AI Enthusiast for a 7–10 month full-time contract.

• Supply Chain Logic Execution: Engineer and update applications managing critical warehouse processes: Purchase Orders, Vendor Management, Warehouse Transfers, and Retail Outlet Product Distribution.
• Deployment & Testing: Deploy the rebuilt applications into the new ERP/WMS system, managing end-to-end testing, error debugging, and final optimization.

Required Qualifications & Expertise

• Deep RPG Domain Knowledge: Extensive, proven experience coding in RPG III, RPG IV, and ILE architectures within ERP/WMS domains.
• AI Tool Fluency: Active, hands-on experience using Claude AI or similar LLMs to interpret code logic, generate code variations, and streamline development pipelines.
• Modern IDE Familiarity: Proficiency using Visual Studio / VS Code for managing source code control, exploration, and editing.
• Functional Supply Chain Experience: Strong understanding of core inventory and logistics workflows: vendor coordination, purchase order cycles, inventory moving, and retail setups.
