💡 A Word from JOBPLOY
Due to the nature of the plastic extrusion and mixing process, shift work, equipment operation, and on-site material handling may be involved, so adherence to workplace safety rules and physical fitness management are important. Learning basic Korean terminology related to machine operation and production processes is advantageous for on-site adaptation, and the environment is stable with commuting support and lunch provided.
