PURPOSE
The MES Engineer ensures the reliable implementation, operation and continuous improvement of the Manufacturing Execution Systems across the manufacturing sites globally. The aim is to guarantee that production processes are supported by stable, compliant, and well-integrated MES solutions that meet the needs of plant operations, quality, and supply chain.
Working under the leadership of the MES Application Owner, the MES Engineer provides day-to-day user support, manages change requests through to implementation, and leads MES deployments and upgrades at local plants. The role works closely with Operations, Global and Regional Process Owner, SCADA Engineering, OT vendors, ERP Application Management and IT infrastructure to ensure that MES solutions deliver value to production teams across multiple sites and regions. Support and further development of our global OT Application strategy
PLACE IN THE ORGANISATION
Reports to:
Collaborates with:
Local Plant and Production Managers
End User (shopfloor workers)
Process and Quality Engineers
OT System Engineers and OT SCADA Engineers
IT Infrastructure and IT Application teams (SAP)
Regional Operational Excellence team
External MES vendors and system integrators
Global and regional project teams
Back up: Other MES Engineer(s) within the OT MES team
DIMENSIONS OF THE JOB
The MES Engineer operates in a multinational chemical manufacturing environment with multiple production sites across different countries and regions. The role combines day-to-day operational support with project-based implementation work.
The position requires regular interaction with plant-floor users (operators, shift leaders, production managers) as well as corporate IT and engineering functions. Travel to local plants for deployments, upgrades, and on-site support is expected (estimated 20–40% of working time, depending on the project portfolio).
The role is both operational and project-oriented, with a strong focus on user support, change management, system reliability, local plant implementations, and compliance with chemical industry regulations and customer requirements. It also requires professional coordinating of external vendors and system integrators, reviewing deliverables, and managing escalations
DECISION-MAKING POWERS
The MES Engineer may propose technical solutions and configuration changes within the MES domain. Changes to production-critical systems require approval from the MES Application Owner. The MES Engineer has authority to prioritise and resolve day-to-day support tickets within agreed service levels.
