PURPOSE The MES Engineer ensures the reliable implementation, operation and continuous improvement of 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. It also supports and further develops the global OT Application strategy.
PLACE IN THE ORGANISATION Reports to: MES Application Owner
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 coordination of external vendors and system integrators, review of deliverables, and management of 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.
KEY RESULT AREAS RESULT AREA 1: User Support and Incident Resolution Aim: Ensure that MES end users across all plants receive timely, effective support to maintain uninterrupted production operations.
Provide second‑line and third‑line support for MES‑related incidents and user queries. First line of support will be provided by the OT‑Support Team.
Diagnose and resolve MES system issues, including configuration errors, interface failures, and data inconsistencies.
Coordinate with IT/OT infrastructure, automation teams, and vendors for escalated issues.
Maintain and update the MES knowledge base, FAQs, and troubleshooting guides for plant users.
Monitor MES system health and proactively address recurring issues.
RESULT AREA 2: Change Management and Follow‑Up Aim: Manage MES change requests from intake through implementation, ensuring changes are properly assessed, tested and deployed.
Receive, log, and assess change requests from plant users, production management, and quality teams.
Perform impact analysis on proposed changes (technical, operational, regulatory).
Implement approved changes through configuration, scripting or module adjustments.
Coordinate testing (unit, integration, user acceptance) with plant stakeholders before deployment.
Follow the company’s change management procedures, including documentation and sign‑off.
Track and report on change request status to the MES Application Owner.
RESULT AREA 3: Local Plant Implementation and Rollout Aim: Successfully deploy MES solutions at local manufacturing plants, ensuring adoption and operational readiness.
Lead or support MES rollouts at new and existing plant sites, including greenfield and brownfield deployments.
Adapt the global MES template to local plant requirements (recipes, equipment, workflows, regulatory specifics).
Conduct site assessments to understand local production processes, infrastructure, and integration needs.
Perform small technical adjustments and test execution.
Coordinate with local plant teams, automation engineers, and IT to plan and execute deployments.
Deliver on‑site commissioning, operator training, and hyper‑care support during and after go‑live.
Document site‑specific configurations, deviations from the global template, and lessons learned.
RESULT AREA 4: System Integration and Data Integrity Aim: Ensure reliable data flow between MES, plant‑floor automation, and enterprise systems across all sites.
Maintain and troubleshoot interfaces between MES and automation systems (PLCs, SCADA, DCS, historians).
Support integration with ERP (SAP) for production orders, material consumption, batch records and goods receipt.
Ensure data integrity and consistency across system layers, including master data alignment.
Support integration with LIMS, QMS and other plant systems as required.
RESULT AREA 5: Documentation and Compliance Aim: Ensure that all MES activities are properly documented and compliant with chemical industry regulations, customer requirements and internal quality standards.
Maintain up‑to‑date system documentation (configuration records, interface specifications, SOPs).
Contribute to validation documentation (URS, FDS, DDS, test protocols, traceability matrices) as required by GMP or chemical safety regulations.
Ensure MES configurations comply with relevant standards (ISA‑95, ISA‑88, FDA 21 CFR Part 11 where applicable).
Support internal and external audits related to MES systems.
Follow agreed templates, methodologies and documentation standards.
RESULT AREA 6: Delivery Within Agreed Time Frame Aim: Contribute to timely and efficient delivery of MES support, changes and projects.
Respect the planning of activities as defined by the MES Application Owner or Project Manager.
Complete assigned tasks and support tickets within agreed service levels and time frames.
Signal risks, delays or deviations in a timely manner.
Apply best practices to ensure quality and efficiency in execution.
PERFORMANCE CRITERIA Knowledge And Experience Diploma: At least a professional bachelor’s degree in engineering, computer science, industrial automation, chemical engineering or a related technical field.
Knowledge
Manufacturing Execution Systems (MES) and ISA‑95 / ISA‑88 standards.
Chemical manufacturing processes (batch, continuous, or hybrid production).
System integration (OPC UA, MQTT, REST APIs, database connectivity).
SQL and relational databases.
Object‑oriented coding (e.g. JAVA).
Basic knowledge in SAP MM/PP.
Automation systems (PLCs, SCADA, DCS) and their role in the manufacturing stack.
ERP integration (preferably SAP PP/PI).
GMP, chemical safety regulations and quality management systems.
Experience 2–5 years of experience in MES support, implementation or administration in a manufacturing environment, preferably in the chemical, pharmaceutical or process industry.
Running‑in period Two months to get to know the company’s MES landscape, IT/OT architecture and internal ways of working. Three to six months to be able to work independently on support, changes and local plant implementations (through on‑the‑job training and site visits). Successful candidate will make a full transition directly to our customer after some period of time.
Languages
English, spoken and written (required for multinational collaboration).
Any other language is an asset (given the multinational plant footprint).
Skills and attitudes
Results‑driven: Works consistently towards predefined objectives and persists in the face of routine obstacles.
Problem‑solving thinking: Comes up with workable solutions for technical problems based on available information, system diagnostics and user feedback.
Technical expertise: Builds and applies deep knowledge of MES platforms, integration patterns and chemical manufacturing processes.

Stakeholder management: Communicates effectively with plant‑floor operators, engineers, OT and IT teams and management at different levels.
Initiative: Shows willingness to learn, improve and take ownership of assigned tasks.
Flexibility: Willing to travel to plant sites and adapt to different local production environments and cultures (up to 40%).
Act in line with the quality system.
Cross‑cultural collaboration across different regions, countries and languages.
Structured and methodical: Approaches configurations, changes and testing with discipline, traceability and compliance awareness.
