■ Job Overview As an engineer capable of providing after-sales support for our new product, WES, you will be engaged in supporting the stable operation of delivered systems. As a Logistics System Service Engineer, you will lead the activities necessary to ensure stable system operation, such as establishing software support structures, providing recovery support for troubles occurring during operation, communicating defect status and improvement activities to the development/design teams, and proposing maintenance services and creating estimates. You will contribute to building the mechanisms that support the operation of the latest systems, bringing innovation to next-generation in-plant logistics.

*Regarding WES (Warehouse Execution System) and WMS (Warehouse Management System) While WMS (Warehouse Management System) focuses on inventory and location management, WES plays the role of controlling robots, automated guided vehicles, sorters, etc., within the warehouse in real-time, optimizing the order and assignment of tasks.

■ Department Role The service department is a "strategic department that balances customer satisfaction and profitability." Beyond conventional after-sales support, we build long-term relationships of trust by providing value that exceeds customer expectations, while simultaneously strengthening our revenue base through the expansion of maintenance contracts and paid services.

Another important role is to circulate the insights gained from customer touchpoints throughout the entire company, linking them to the improvement of the overall business competitiveness.
