About the role
Our client, a rapidly growing, venture-backed logistics and fulfillment company, is building a next-generation, custom Warehouse Management System (WMS) from the ground up - along with the full ecosystem of operational systems that surround it. This is not just a WMS: the scope includes the end-to-end operational technology stack, spanning real-time inventory control, order management, carrier and EDI integrations, 3PL connectivity, and ERP-adjacent workflows. The platform will replace the current operations stack and transform how the company manages warehouse operations at scale.
