• Assess site readiness and physical/process model gaps; document processes and data flows, identify local deviations, and drive implementation decisions.
• Facilitate cross-functional alignment and translate manufacturing, quality, operations, and compliance needs into clear requirements (process, functional, and data) and acceptance criteria.
• Build process models based on business specifications and assist the business experts in preparing and executing MES based process models.
• Serve as the primary implementation coordinator between site leadership, operations, process engineering, quality, OTG, IT, and external consultants.
• Coordinate with IT and site members on ERP manufacturing master data, transactional flows, interface behavior, exception handling, and cutover dependencies between the MES and the ERP.
• Maintain site governance for scope, requirements traceability, and controlled template changes.
• Coordinate testing and validation, including scenario development, System Integration Testing (SIT) support, User Acceptance Testing (UAT), defect triage, regression testing, data validation, and readiness criteria.
• Lead operational readiness and change-management activities, including stakeholder communications, impact assessments, procedure updates, training plans and materials, train-the-trainer delivery, and support-model preparation.
• Coordinate site data readiness, cutover, go-live, and hypercare; track stabilization and transition the solution to ongoing support.
• Capture lessons learned, improve site implementation playbooks, templates, checklists, estimates, and governance, and prioritize post-go-live improvements from operational feedback.

• Bachelor’s degree in Engineering, Computer Science, Information Technology, Manufacturing Systems, or a related discipline, or equivalent practical experience.
• 8+ years of experience in a manufacturing environment, including 3+ years working with MES, or digital shop-floor implementations.
• Experience participating in or leading at least one MES, digital manufacturing, or shop-floor system implementation across multiple lifecycle phases.
• Hands-on experience with Siemens Opcenter Execution Semiconductor or another enterprise MES platform preferred.
• Experience with SAP-to-MES integration, manufacturing master data, interface testing, or production transaction flows preferred.
• Experience in semiconductor, high-tech, regulated, or other complex manufacturing environments preferred.
• Familiarity with Lean, Six Sigma, or other structured process-improvement methods preferred.
• Project management or change management certification preferred.

Key Skills

• Working knowledge of data mapping, SQL/reporting, APIs or middleware, and industrial automation interfaces.
• Ability to influence without direct authority and communicate effectively with operators, engineers, site leaders, IT/OT teams, consultants, and program leadership.
• Strong analytical, organizational, and problem-solving skills; able to work independently and manage competing priorities.
