💡 A Word from JOBPLOY
Since Sunjin General specializes in medium-to-high-speed ship engine and generator repair, field maintenance frequently involves handling heavy mechanical parts and using precision tools. As engine part names and maintenance manuals are often written in English or technical terminology, familiarity with basic mechanical terms is advantageous for job adaptation. Due to the nature of work on ships and in factories, it is important to strictly follow safety protocols, such as wearing safety shoes and goggles, and to maintain communication with team members.
