Summary

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" Microsoft ecosystem, 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.

Detailed Description
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.

Technical Leadership: Act as the primary subject matter expert (SME) for the development team, providing guidance on best practices for cloud integration and modern UI/UX design.

Knowledge/Skills/Competencies
Required Technical Skills

Technical writer: Document the legacy system architecture, its functionalities, business logics

Modern Stack: Expert-level experience in C# / .NET, Azure Cloud Services (App Services, Service Bus, Data Factory), and SQL Server.

Legacy Fluency: Proven ability to read and interpret VB6 code and Excel VBA/Macros. Experience querying and migrating from IBM DB2 is a good plus

Professional Experience

10+ years in software development, with at least 3 years in a Lead or Architect role.

Proven track record of successfully retiring legacy systems in a manufacturing or industrial environment.
Experience in Business Process Re-engineering (BPR)—not just moving code to the cloud, but improving the process itself.
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.

Analytical Rigor: A passion for deconstructing "spaghetti code" to find the underlying business value.

Data Modeling: Strong experience in relational database design and transitioning from legacy schemas to modernized, performance-optimized cloud data models.

DevOps: Familiarity with Azure DevOps for CI/CD, version control, and project tracking.
