💡 JOBPLOY's Comment

PLASM Co., Ltd. is a technology-intensive SME that manufactures precision plasma equipment for semiconductors and displays. As the production and assembly site requires an understanding of precision component handling and cleanroom environments, adherence to safety rules and basic drawing and mechanical assembly skills are important. Given the nature of the small workplace with around 10 employees, frequent inter-departmental collaboration is required, so smooth Korean communication skills and a diligent work attitude are recommended.
