LG Energy Solution Michigan Inc. (LGESMI) develops and manufactures large lithium-ion polymer batteries and packs for electric vehicle (EV) and energy storage applications. Come join the leader in advanced EV batteries!

The Senior Engineer, PLC Automation is an ESMI-based controls engineer responsible for providing specialized automation and technical support to LG Energy Solution and affiliated manufacturing entities throughout North America.

This position supports the development, deployment, commissioning, startup, stabilization, troubleshooting, and optimization of PLC-based control systems used in lithium-ion battery electrode mixing processes. The Engineer serves as a technical expert in LG Energy Solution electrode mixing control programs, PLC and HMI systems, recipe management, alarm management, NMP process control, automated material handling, and manufacturing-system communications.

The Engineer travels to North American manufacturing sites to support new-line launches and production ramp-ups, resolve complex control-system and process-automation issues, implement control-logic improvements, and transfer specialized knowledge to locally hired controls engineers and maintenance personnel.

• Provide advanced PLC, HMI, and automation engineering support to ESMI and other LG Energy Solution or affiliated North American manufacturing entities.
• Support the deployment, configuration, commissioning, startup, and optimization of control programs used in lithium-ion battery electrode mixing systems.
• Develop, modify, test, and troubleshoot PLC programs using Siemens, Mitsubishi, LS, and Omron control platforms.
• Develop and optimize HMI screens, equipment interfaces, operator controls, process-monitoring functions, and production-status displays.
• Develop, modify, and validate recipe-management functions supporting different battery products, materials, process conditions, and production requirements.
• Develop and optimize process-control logic for electrode mixing systems, including NMP piping pressure control, material transfer, automated cleaning, and related process sequences.
• Develop, modify, and troubleshoot automated Pig system programs used for material transfer, piping recovery, cleaning, and process-efficiency improvement.
• Develop and commission communication interfaces between electrode mixing equipment and Automated Guided Vehicles or other automated material-handling systems.
• Manage alarm lists, interlock logic, fault conditions, equipment status signals, and process-monitoring functions.
• Diagnose and resolve complex PLC, HMI, network communication, instrumentation, control‑sequence, equipment‑interface, and process‑automation issues.
• Support line acceptance testing, equipment commissioning, trial production, production ramp‑up, and mass‑production stabilization.
• Analyze recurring equipment faults, process interruptions, communication failures, and control‑system performance issues; conduct root‑cause analysis and implement corrective actions.
• Modify control programs and operating sequences to improve process stability, equipment reliability, cycle time, production efficiency, and product quality.
• Develop production‑reporting, work‑log management, and equipment‑performance applications supporting manufacturing operations.
• Review and update electrical drawings, control‑panel drawings, I/O lists, network architectures, equipment specifications, and control‑system documentation.
• Coordinate technical activities with process engineering, manufacturing, maintenance, IT, equipment suppliers, contractors, and engineering teams across multiple entities and locations.
• Maintain controlled records of PLC and HMI software versions, program changes, parameter modifications, testing results, alarms, and corrective actions.
• Train locally hired controls engineers, technicians, operators, and maintenance personnel on PLC architecture, HMI operation, recipe management, alarm response, equipment…
