MES Integration Engineer

The MES Integration Engineer (Mid-Level) is responsible for designing, implementing, and maintaining MES solutions that integrate seamlessly with automation systems (PLC/SCADA), ERP platforms, and production environments. This role requires hands-on experience in system integration, configuration, testing, and troubleshooting of MES applications in industrial environments.

Key Responsibilities:

• Lead and execute MES integration activities across the project lifecycle – design, development, testing, deployment, and support.

• Collaborate with production, automation, and IT teams to understand system requirements and deliver tailored MES solutions.

• Design and configure MES modules such as Work Order Management, Electronic Batch Records (EBR), Track & Trace, Downtime Analysis, etc.

• Interface MES with PLC/SCADA/DCS systems and higher-level systems like ERP (SAP, Oracle) using protocols like OPC UA, MQTT, REST APIs, SQL, XML/JSON.

• Conduct FAT/SAT/UAT and validation activities ensuring systems meet GMP, FDA 21 CFR Part 11, or other regulatory standards.

• Write and maintain system documentation including functional specifications, design documents, and validation reports.

• Analyze production workflows and recommend system enhancements or automation solutions.

• Provide on-site and remote technical support during commissioning and post go-live.

Key Focus Areas:

1. MES Platforms & Functional Modules

   • Hands-on experience with platforms like Siemens Opcenter, Rockwell FTPS, AVEVA/Wonderware MES, Werum PAS-X, GE Proficy, or Ignition.

   • Configure and deploy MES functionalities like Recipe Management, Quality Data Logging, Batch Records, Performance Monitoring.

2. Systems Integration (PLC/SCADA/ERP)

   • Design and implement real-time data exchange between shop-floor equipment and MES using OPC UA, MQTT, RESTful APIs.

   • Integrate MES with SCADA systems (e.g., WinCC, iFIX, Ignition) and ERP systems (SAP, Oracle, etc.).

3. Database & Scripting Knowledge

   • Work with SQL Server, PostgreSQL, or Oracle for MES data logging, reporting, and troubleshooting.

   • Use scripting languages (e.g., JavaScript, Python, XML, VBA) for customization, logic, and UI enhancements.

4. Testing, Validation & Compliance

   • Plan and execute FAT, SAT, IQ/OQ/PQ testing phases.

   • Ensure compliance with GMP, GAMP5, and data integrity regulations where applicable.

5. Project Execution & Documentation

   • Prepare technical documentation: user stories, interface control documents, test cases, and SOPs.

   • Manage change requests, configuration control, and versioning of MES solutions.

6. Customer Interaction & Problem Solving

   • Liaise directly with clients during workshops, testing, and commissioning phases.

   • Troubleshoot integration and system-level issues in live environments.

7. Continuous Improvement & Best Practices

   • Contribute to the evolution of standard templates, reusable code libraries, and integration frameworks.

   • Stay updated on Industry 4.0, IIoT, and digital manufacturing trends.

Qualifications & Requirements:

• Education: B.E./B.Tech or M.Tech in Computer Science, Electrical, Instrumentation, Mechatronics, or Industrial IT.

• Experience: 3–6 years in MES integration or digital manufacturing systems.

• Technical Skills:

  • Strong understanding of manufacturing processes and industrial control systems.

  • Experience with databases, scripting, APIs, and industrial communication protocols.

• Soft Skills:

  • Strong analytical and troubleshooting ability.

  • Effective communication with both technical and non-technical stakeholders.

  • Time and project management skills with ability to work independently.
