Oversee and verify hardware/software readiness for IT equipment deployments; supervise preparation and installation activities.

MES Development & Operation

Provide technical support and troubleshooting for MES applications; maintain system reliability and performance.
Design and develop transportation logic for logistics automation.

Process Innovation (PI)

Identify and implement process improvement and innovation opportunities within manufacturing operations.
Utilize big data from production, process, quality, and equipment sources to analyze defects, predict failures, and optimize processes through real-time data analysis.
Develop and implement Smart Factory solutions aligned with business objectives.

Collaboration & Documentation

Work closely with cross-functional teams (Production, Engineering, Quality, IT) to align MES and PI initiatives with business goals.
Lead and manage MES/PI projects, ensuring timely delivery within scope and budget.
Develop training materials and conduct training sessions for end-users.
Create and maintain detailed documentation for MES processes and systems.
Monitor system performance, user feedback, and industry trends to continuously improve solutions.
Perform routine (daily, monthly, etc.) system checklists and submit reports.

Qualifications:

Education

Bachelor's degree in Computer Science, Information Technology, Engineering, or a related field.

Experience

8+ years of experience in MES solution development and operation.
Experience in automation within high-tech industries such as solar or semiconductors.

Language

Korean fluency required; working-level English proficiency (reading, written communication).

Technical Skills

Proficiency in MES software (e.g., Miracom MESPlus, LG CNS EzMES, ThiraUtech OpenMES, Wonderware, Siemens SIMATIC IT, Rockwell FactoryTalk).
Strong understanding of equipment communication protocols (SEMI standard, OPC, PLC).
Strong knowledge and experience in developing and designing manufacturing processes and platforms.
Proficiency in Java-based application development (front-end and back-end).
Advanced database skills including query analysis, performance tuning, and stored procedure development (Oracle, MS-SQL).
Strong analytical and problem-solving skills; ability to analyze complex data and develop actionable insights.
Excellent verbal and written communication skills; ability to convey technical information to non-technical stakeholders.
Proven experience in managing projects from inception to completion.

Preferred Qualifications:
