About The Position

We are seeking an experienced AS400 / IBM i Developer with WebSphere EDI expertise to take full operational ownership of a homegrown port and logistics management platform. The proprietary IBM i core has evolved alongside IBM WebSphere to support real-time port operations, including container tracking, terminal yard management, dispatching, and automated B2B data exchange.

The role involves conducting code forensics on a custom legacy codebase, mapping WebSphere middleware integration channels, and becoming the primary subject matter expert. The Lead Developer will lead future AS400 development, modernize EDI data pipelines, optimize system performance, and provide tier-3 support for the core port and logistics ecosystem.

Requirements

• Experience as an AS400 / IBM i Developer.
• WebSphere EDI expertise.

Responsibilities

• Reverse-engineer homegrown RPG/CL programs and DB2 tables to document business rules, data structures, and custom workflows.
• Maintain, configure, and expand IBM WebSphere middleware, including WebSphere MQ, Integration Bus, and B2B, for automated EDI communications with shipping lines, customs agencies, rail providers, and trucking fleets.
• Develop and update maps for maritime and logistics EDI transaction sets, including 210, 214, 301, 310, 322, 850, and 856.
• Serve as the primary developer responsible for system stability; troubleshoot failed EDI transmissions and translations, resolve spool and batch job issues, and apply emergency bug fixes.
• Design and implement REST/SOAP APIs, WebSphere messaging channels, and database connectors to link the AS400 core with modern web and SaaS port operations tools.
• Document business logic, system architecture, database schemas, and WebSphere routing paths to reduce single-point-of-failure risks.
• Lead future AS400 development, modernize EDI data pipelines, optimize system performance, and provide tier-3 support.
