We are looking for a highly skilled Lead Systems Architect to spearhead the modernization of our core manufacturing execution and business support systems. This is a high-impact role requiring a unique blend of\ "archaeological\" engineering—uncovering and understanding legacy business logic embedded in VB6, DB2, and Excel Macros —documenting the system functionality, logics, integration and database diagram. Ultimately to enable the seamless integration between legacy systems to other IT enterprise platforms.
You will be responsible for translating complex, legacy factory processes into a\ "state-of-the-art\" Microsoftecosystem, ensuring a seamless transition that minimizes production downtime while maximizing scalability and data integrity.
This is a permanent, strategic position. Following the successful delivery of the modernization project, you will take ownership of our regional solution roadmap, ensuring our ecosystem remains at the cutting edge and scaling these solutions across new markets.
Key Responsibilities
* Legacy Discovery: Deep-dive into existing on‑premise applications (Visual Basic 6.0, DB2) and complex Excel-based workflows to document its business rules and data dependencies.
* Stakeholder Engagement: Collaborate directly with factory floor managers and business leads to document\ "as-is\" processes and define\ "to-be\" requirements.
* Architectural Design: Design a comprehensive, cloud‑native or on‑premises target architecture leveraging the Microsoft Stack (Azure Functions, Logic Apps, SQL, .NET 8+, Power Platform).
* Migration Roadmap: Develop a phased project plan that addresses data migration, risk mitigation, and parallel running strategies to ensure zero disruption to manufacturing.

* Strong project management background (Agile/Scrum) with the ability to build and manage a multi‑quarter migration timeline.
* Manufacturing Background: Experience with MES (Manufacturing Execution Systems) or SCADA integration is a significant plus.
* Soft Skills
* The\ "Translator\" Ability: Can speak\ "factory\" with shop‑floor operators and\ "strategy\" with executive stakeholders.
