ERP Modernization Architect

Job Description Job Summary

We are seeking an ERP Modernization Architect to drive the evolution of our IBM i (AS/400) Mincron ERP environment. Mincron is our system of record and we are committed to getting the most out of it -- enhancing it where we can and extending it where we cannot. Our RPGLE development team is experienced and capable, and this role works alongside them to help prioritize and shape native Mincron enhancements while also addressing the gaps that the platform cannot fill on its own.

Where Mincron has limitations, this role is responsible for designing the right solution around them -- whether that is a functional overlay in a modern language, an agentic AI workflow to automate a manual process, or a data connector that enables trading partner ERP integration. This person will also guide our UI modernization effort, providing architectural direction on our active Lansa rollout and evaluating whether Lansa remains the right long-term approach.

This is a hands‑on individual contributor role reporting directly to the VP of IT .

• Work with the ERP Development Manager and RPGLE development team to identify, prioritize, and shape native Mincron enhancements — understanding the business need, determining whether it can be addressed within the ERP, and helping get it scoped and sequenced against other work.
• When native Mincron cannot address a business need, design the right solution around that limitation — whether an overlay in a modern language, an automated workflow, or an integration — and see it through to delivery.
• Serve as the architectural authority for our UI modernization effort — providing guidance on Lansa configuration and design decisions as the RPGLE team executes the active rollout, while also evaluating whether Lansa remains the right long‑term approach or whether an alternative strategy better serves our needs.
• Design and build functional overlay solutions using modern languages (Python, Node.js, Java, C#, or similar), REST APIs, and DB2 for i stored procedures to deliver capabilities the native ERP cannot provide.
• Evaluate and implement agentic AI solutions to automate manual ERP workflows, building processes that are reliable, auditable, and operationally safe.
• Architect and build data connectors for trading partner ERP‑to‑ERP integration covering electronic ordering and invoicing, including API‑based B2B connectivity, data contracts, and documented, supportable interfaces.
• Define and maintain the overall ERP integration architecture — data flows, authentication patterns, error handling, and monitoring — as a framework the development team can extend over time.
• Review technical designs before work begins to ensure alignment with the modernization roadmap and catch architectural problems early.
• Work alongside the RPGLE development team to introduce and evaluate modern development tools and workflows — including Git, VS Code, and AI‑assisted coding tools — approaching adoption as a collaborative, shared effort that respects the team's experience and existing practices.
• Engage with business stakeholders to surface unmet needs, determine the right delivery approach, and validate that solutions address the real operational problem.
• Document architectural decisions, integration patterns, and system design. Stay current on AI tooling and integration platforms and bring informed recommendations to leadership.
• Other duties as assigned.

• Bachelor's degree in Computer Science, Information Systems, or a related field — or equivalent professional experience.
• Hands‑on experience building integration or overlay solutions in one or more modern languages (Python, Node.js, Java, C#, or similar). This is the primary new development work for this role.
• Demonstrated experience designing and implementing REST API integrations, including exposing backend data via APIs and consuming external APIs.
• Experience building B2B data connectors or ERP‑to‑ERP integrations — EDI, API‑based trading partner connectivity, or iPaaS platforms.
• Experience working within or alongside a legacy ERP environment,…
