💡 A Word from JOBPLOY
Aircraft parts machining and assembly is a field that requires strict precision and compliance, where even the slightest error is not tolerated. Since it is very important to accurately understand and follow design drawings and work standards, it is advantageous to be familiar with basic Korean work terminology and drawing notation. In addition, due to the nature of the manufacturing industry where handling of machining equipment and tools is frequent, diligence and meticulous work while strictly adhering to on-site safety rules are required.
