• Benefits: We provide severance pay, four major insurances, special performance bonuses (4 times a year), environmental/machinery/molding allowances, commuter bus operation (separate travel expenses paid for commuters from outside the region), in-house cafeteria (breakfast/lunch/dinner provided), dormitory operation, awards for excellent employees, long-service awards, holiday gifts, support for club activities, and health management linked with designated university hospitals.

💡 A Note from Jobploy
Sungil New Materials is a company that produces construction and industrial materials based on GRP composite materials, primarily offering production line jobs. Welfare benefits necessary for foreign workers, such as dormitories, meals, and commuter buses, are well-equipped, so a stable working environment can be expected. Since the work mainly involves handling reinforced plastic molded products in the production process, it will be a good opportunity if you have relevant experience or a willingness to learn.
