EDI & Integration Architect

Millennium-•Madison, WI

About The Position

The EDI & Integration Architect owns the architecture and ongoing support for data exchanges between Millennium systems. The role evaluates integration needs and selects appropriate approaches, including Celigo, native or vendor-provided connectors, direct APIs, and file-based exchanges. It is the primary technical owner of Celigo integrator.io and Celigo B2B Manager, including EDI trading partner onboarding, maintenance, monitoring, and error resolution. The architect serves as Millennium’s primary technical contact for trading partners, works with implementation partner Stratus Green to bring flow development in-house, and collaborates with the NetSuite Administrator to diagnose and resolve integration issues. The role leads integration design and lifecycle management, builds and maintains Celigo flows and related mappings, and manages EDI partner connections and AS2 certificates. It monitors integration logs and error queues, investigates root causes, coordinates testing and go-lives with external partners, manages Celigo support requests, and maintains technical documentation and runbooks. A structured knowledge-transfer plan will support the transition of external flow development to internal ownership.
