Summary: The Engineer II, Battery Filling Equipment is an ESMI-based engineer responsible for providing specialized technical support to LG Energy Solution and affiliated manufacturing entities throughout North America.
This position supports the installation, commissioning, startup, model changeover, production stabilization, troubleshooting, maintenance, and optimization of lithium-ion battery electrolyte filling equipment. The Engineer serves as a technical expert in high-volume electrolyte filling processes, precise electrolyte-volume control, Hibar pump systems, filling nozzles, vacuum chambers, and related mechanical and pneumatic systems.
The Engineer travels to North American manufacturing sites to support new production-line launches, resolve complex equipment and process issues, improve filling accuracy and equipment reliability, and transfer specialized operational and maintenance knowledge to locally hired engineers and technicians.
Responsibilities: - Provide advanced technical support for electrolyte filling equipment at ESMI and other LG Energy Solution or affiliated North American manufacturing entities.
- Lead or support equipment installation, mechanical checkout, setup, commissioning, acceptance testing, startup, trial production, and mass-production stabilization.
- Diagnose and resolve complex electrolyte filling equipment issues involving filling pumps, nozzles, piping, valves, vacuum chambers, sensors, actuators, pneumatic systems, and related control interfaces.
- Establish, adjust, and optimize electrolyte filling parameters to maintain accurate and consistent fill volumes during high-volume production.
- Identify and correct electrolyte-volume hunting, filling variation, inconsistent discharge, pressure instability, and other conditions affecting process capability and product quality.
- Perform advanced maintenance, inspection, repair, setup, and troubleshooting of Hibar pumps and associated electrolyte-delivery components.
- Calibrate, inspect, clean, maintain, and replace filling nozzles and related components to ensure accurate electrolyte dispensing and reliable equipment operation.
- Detect and resolve vacuum chamber leakage, sealing failures, pressure loss, and related vacuum-performance problems.
- Analyze equipment failures, filling defects, downtime, and process variation; conduct root-cause analysis and implement sustainable corrective and preventive actions.
- Support product model changeovers by identifying required equipment modifications, changing tooling and settings, validating filling conditions, and confirming readiness for mass production.
- Support notching and stacking equipment setup, commissioning, troubleshooting, and optimization when required by the assigned project.
- Provide rapid on-site technical support during new plant launches, production ramp-ups, major equipment failures, quality incidents, and other critical manufacturing events.
- Review mechanical drawings, pneumatic diagrams, equipment layouts, technical specifications, and operating manuals to diagnose problems and recommend equipment improvements.
- Recommend and implement mechanical, pneumatic, sealing, and process improvements to increase filling accuracy, equipment reliability, production yield, and throughput.
- Coordinate technical activities with manufacturing, maintenance, quality, process engineering, equipment suppliers, contractors, and engineering teams across multiple entities and locations.
- Document equipment settings, filling parameters, inspection results, troubleshooting findings, corrective actions, lessons learned, and standardized maintenance procedures.
- Train locally hired engineers, technicians, operators, and maintenance personnel on filling-equipment operation, Hibar pump maintenance, nozzle calibration, vacuum-system inspection, and troubleshooting methods.
- Travel frequently to manufacturing facilities throughout North America based on project and operational requirements.
