About the Project

To support international growth and an ambitious global ERP rollout within a leading multinational industrial enterprise, the client is scaling its engineering capacity. The team is actively expanding and tailoring its core ERP platform, Wynne RentalMan, across multiple international markets.

The initiative is currently focused on a critical milestone involving go-lives across key markets in the Middle East and Europe, followed by several additional country onboardings throughout 2027. We are looking for an experienced IBM i / RPG Developer to hit the ground running, help meet these deployment targets, and deliver robust ERP solutions.

• Support international country rollouts, including specific local compliance and financial flows such as E-invoicing.
• Ensure smooth version control and deployments using Aldon (Change Management).
• Oversee end-to-end application lifecycle management, from technical design to testing and deployment.
