MES Engineer

Job Description

\n

Position Summary

\n

We are seeking a hands-on MES Engineer to support the deployment, integration, commissioning, and ongoing operation of Manufacturing Execution Systems (MES) across lithium-ion battery cell, module, and pack production lines.

\n

This role connects shop-floor equipment, supervisory control applications, and manufacturing systems to enable reliable data exchange, production execution, and end-to-end traceability. The successful candidate will work closely with manufacturing, process engineering, controls, quality, IT, and MES development teams to support production readiness and continuous improvement.

Key Responsibilities

\n

\n
• MES Deployment and Commissioning: Install, configure, test, and commission MES interfaces and shop-floor applications, including SCADA, HMI, and PC-based equipment software. Validate system functionality against production workflows and process requirements.
\n
• Equipment and System Integration: Develop, configure, and troubleshoot interfaces between MES, equipment applications, PLCs, and enterprise systems. Support the exchange of production orders, process parameters, equipment status, quality results, material tracking, and production counts.
\n
• Data Reliability and Traceability: Monitor data collection and transmission to ensure accuracy, completeness, and timely availability. Investigate missing records, communication delays, duplicate transactions, and traceability gaps, and implement corrective actions.
\n
• Production Troubleshooting: Provide on-site technical support during equipment startup, production ramp-up, and routine operations. Diagnose software defects, interface failures, configuration issues, and communication faults to minimize production disruption.
\n
• System Enhancement: Translate manufacturing requirements into system improvements. Support changes to production workflows, data collection, process controls, and reporting as manufacturing processes evolve and production capacity expands.
\n
• Testing and Change Implementation: Participate in requirements reviews, integration testing, user acceptance testing, and production release activities. Coordinate system changes with relevant teams and maintain clear validation and change records.
\n
• Documentation and Training: Prepare interface specifications, commissioning procedures, operating instructions, and troubleshooting guides. Train production and maintenance personnel on system operation and common issue resolution.
\n
• Cross-Functional Collaboration: Partner with controls engineers, equipment suppliers, process engineers, quality teams, IT, and MES developers to resolve integration issues and support successful project delivery.

• Bachelor’s degree in Computer Science, Software Engineering, Electrical Engineering, Automation, Mechatronics, Manufacturing Engineering, or a related field, or an equivalent combination of education and relevant experience.
\n
• At least 3 years of experience in MES implementation, manufacturing systems integration, or shop-floor software commissioning in an automated manufacturing environment.
\n
• Hands-on experience integrating MES with equipment-level applications, SCADA/HMI systems, or PLCs.
\n
• Proficiency with at least one relevant development language or platform, such as C#/.NET, Siemens WinCC, AVEVA InTouch, GE iFIX, or LabVIEW.
\n
• Working knowledge of MES functions, including production execution, process parameter management, data acquisition, quality tracking, equipment monitoring, and product genealogy.
\n
• Experience with integration technologies such as OPC UA/DA, REST APIs, web services, and database interfaces.
\n
• Familiarity with industrial communication protocols such as Modbus TCP, PROFINET, or EtherNet/IP.
\n
• Experience with SQL Server, Oracle, or MySQL, including writing SQL queries and troubleshooting manufacturing data.
\n
• Strong analytical, troubleshooting, documentation, and cross-functional communication skills.
\n
• Ability to work on-site in a manufacturing environment and support commissioning activities and production needs.
