This includes designing and implementing automation, defining system interfaces, and acting as a source-data expert for all related data applications. You'll also integrate manufacturing systems with databases, PLCs, HMIs, and IoT devices.
- Project Leadership & Support: Lead and support MES projects from conception to deployment. This involves providing guidance on best practices, evaluating member projects, ensuring system scalability, and performing system testing (unit, integration, and user acceptance). You'll also support manufacturing process change management.
- Analysis & Optimization: Work closely with manufacturing engineers to analyze workflows, identify requirements, and translate them into technical specifications. Design solutions for production tracking, quality management, and inventory control, supporting continuous improvement and lean manufacturing initiatives.
- Documentation & Reporting: Create detailed solution architecture documents, configuration guides, and operational manuals. Design and implement real-time manufacturing dashboards and reporting systems.
