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.

- 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.
