Role Overview
The Lead Software Engineer will lead the design, development, and delivery of a Windows-based sortation and labeling platform that integrates with PKMS/WMS systems, PLCs, and material handling equipment (MHE) across our distribution network. The system processes TCP socket messages for carton lifecycle events, persists data to enterprise databases, and coordinates downstream services. This role requires deep hands-on C#/.NET expertise, subject-matter depth in warehouse automation and MHE, and close collaboration with cross-functional business, DC operations, and third-party vendor teams such as Savoye, Opex, Honeywell Intelligrated, Boxer, and bagger/print-and-apply solution providers.
