About this role.
This remote position seeks a developer with strong hands-on experience in RPG/RPGLE on IBM AS400/iSeries and JD Edwards EnterpriseOne development tools. The ideal candidate will develop, debug, and maintain custom programs, support JDE modules, and manage integrations via APIs, EDI, and SQL. The role requires deep technical expertise across both platforms, troubleshooting production issues, and collaborating with functional and infrastructure teams. It is not an infrastructure admin or functional consultant role; it demands dual technical proficiency.

Cover letter sample
Dear Hiring Manager,
I am writing to express my strong interest in the Remote RPG/AS400 & JD Edwards EnterpriseOne Developer position. With over [X] years of hands-on development in RPG/RPGLE and CL on IBM AS400/iSeries, combined with practical experience customizing JD Edwards EnterpriseOne solutions, I am confident in my ability to meet and exceed your technical requirements.
In my previous roles, I have successfully developed and maintained custom RPG programs, designed UBEs and business functions, and resolved complex production issues across integrated systems. I have deep experience with Object Management Workbench, NERs, table conversions, and DB2 SQL, and I thrive in collaborative environments where I can work with functional teams to deliver effective business solutions.
I am particularly excited about this opportunity because it allows me to blend two technical passions: legacy IBM i development and modern ERP customization. I am accustomed to remote work and excel at communicating with international teams at a B2+ English level. I look forward to the possibility of contributing to your projects and would welcome an interview to discuss how my background aligns with your needs.
Sincerely,
[Your Name]
Sample interview questions
I built an integrated inventory reconciliation program that pulled data from multiple files, performed complex calculations, and updated the JDE F4102 table directly. It replaced a manual process, reduced errors by 30%, and improved nightly processing time from 45 minutes to under 10.
First, I gather logs from both the JDE UBE logs and the AS400 job log. I trace the data flow from the report to the RPG program, identify whether the issue is data-related or logic-related, and then isolate the exact step. I use debug tools and may temporarily add trace statements to pinpoint the failure, then apply a fix and test in the lower environment before promoting.
I would open the NER in OMW, analyze the current logic, and make the changes using the Event Rules Design. I would then check all applications that reference that NER and run regression tests. I also review the generated C code or (better) use the JDE test environment to simulate scenarios. Documentation and sign-off from functional analysts are mandatory before moving to production.
I created a stored procedure to automate the extraction of sales data from JDE tables (F4211, F4201) and output it to a flat file for an external CRM. I used embedded SQL in RPGLE and also wrote SQL triggers to synchronize production statuses. This reduced manual data entry and ensured real-time accuracy for the sales team.
I start by understanding the business process and the data mapping requirements. For EDI, I use JDE's EDI modules and map the segments to JDE transactions. For APIs, I design the XML/JSON structure, use JDE's web services (via BSSV or orchestrations), and ensure error handling and retries. I test thoroughly in a sandbox, verify data integrity, and monitor production runs.
This is a remote position.
