EDI & Integration Architect

Millennium-•Delavan, WI

About The Position

The EDI & Integration Architect owns the architecture and support of integrations that exchange data between Millennium systems. The role evaluates integration requirements and selects an appropriate approach, such as Celigo, native or vendor-provided connectors, direct APIs, or file-based exchanges. It is the primary technical owner of Celigo integrator.io and Celigo B2B Manager, including EDI trading partner onboarding, maintenance, and error resolution. The architect serves as Millennium’s main technical contact for trading partners, works with implementation partner Stratus Green to bring flow development in-house, and partners with the NetSuite Administrator to investigate integration issues. The role leads integration design and lifecycle support, administers Celigo platforms and custom flows, onboards and maintains EDI trading partners, monitors integrations, and investigates root causes of failures. It also manages partner and vendor relationships, maintains technical documentation, and transfers knowledge and development capabilities from external partners to internal ownership.
