• 8+ years of expertise in HCL Commerce and/or IBM WebSphere Commerce (WCS) 8.x, covering store customization, commands/tasks, tools, catalog/order/user/organization flows, and back-end integration
• 8+ years of expertise in Java / J2EE and OOD on large IT systems, with WebSphere Application Server strongly preferred
