Employment Type: Contract (W2 through ZipStaff — No C2C or 1099)

About the Opportunity:

ZipStaff is seeking a Lead Developer to own the AS400 core and WebSphere EDI integrations at a major port and terminal operator.

You will reverse-engineer RPG and CL, maintain WebSphere MQ / Integration Bus / B2B for EDI with shipping lines, customs, rail, and trucking, and build APIs that connect the AS400 to modern port tools. This is a hands-on lead seat, not a coordinator role.

What You’ll Do:

Reverse-engineer homegrown RPG/CL programs and DB2 tables to map business rules, data structures, and workflows.
Maintain, configure, and expand IBM WebSphere middleware (MQ, Integration Bus, B2B) for automated EDI.
Develop and update maps for maritime and logistics EDI sets: 210, 214, 301, 310, 322, 850, and 856.
Troubleshoot failed EDI transmissions and translations, spool and batch jobs, and apply emergency fixes.
Design REST/SOAP APIs, WebSphere messaging channels, and database connectors from the AS400 to modern web and SaaS tools.
Document undocumented business logic, schemas, architecture, and WebSphere routing paths.

Required Qualifications:

8+ years hands-on IBM i / AS400 development with RPG and CL.
IBM WebSphere middleware: MQ, Integration Bus, or B2B.
EDI mapping and translation, including maritime or logistics transaction sets (210, 214, 301, 310, 322, 850/856).
DB2 on AS400.
Troubleshooting failed EDI transmissions, spool, and batch jobs in production.
REST or SOAP API design and database connectors.
Able to work on-site in Newark, NJ.
Must be legally authorized to work in the United States without sponsorship now or in the future.

Preferred Qualifications:

Port, terminal, shipping, or logistics domain.
System modernization from AS400 to web or SaaS.
Documentation of undocumented legacy systems.

Benefits:

Health Insurance.
Dental Insurance.
Vision Insurance.
401(k) + 401(k) matching.
Paid time off.
Referral Program.
