Job Description

We are seeking an experienced AS400 / IBM i Developer with strong WebSphere and EDI expertise to take full operational ownership of a homegrown port and logistics management platform.

The ideal candidate will perform code forensics on the custom legacy codebase, map existing WebSphere middleware integration channels, and become the primary Subject Matter Expert (SME) for the platform. This role will lead future AS400/IBM i development, modernize EDI data pipelines, optimize system performance, and provide Tier-3 support for the core port and logistics ecosystem.

Strong proficiency in RPG IV, RPGLE, Free-Format RPG, RPG III, and RPG II .
Hands-on experience with IBM WebSphere MQ, Integration Bus/App Connect, B2B Integrator, or Partner Gateway .
Strong experience with CL/CLLE, DB2 for i, SQL/400, and Embedded SQL .
Strong knowledge of ANSI X12 and EDIFACT standards, EDI mapping, translation, and integration.
Experience with AS2, FTP/SFTP, and WebSphere MQ transport protocols.
Proven ability to reverse-engineer complex, undocumented legacy applications.
Strong troubleshooting, analytical, and problem-solving skills.

Preferred: Experience in port operations, container terminals, freight forwarding, warehousing, transportation management systems (TMS), or logistics. Experience with PHP, Python, Node.js, Profound UI, Fresche, or Looksoftware is a plus.

Key Traits

Self-driven investigator who can analyze legacy code, job streams, spool queues, and undocumented business logic.

Ability to bridge complex AS400/WebSphere architecture with the operational needs of port and logistics teams.
