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.

• 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.

• 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.

• The "Translator" Ability: Can speak "factory" with shop-floor operators and "strategy" with executive stakeholders.

• Data Modeling: Strong experience in relational database design and transitioning from legacy schemas to modernized, performance-optimized cloud data models.
• Dev Ops: Familiarity with Azure Dev Ops for CI/CD, version control, and project tracking.

• Duties of this position are performed in a normal office environment.
