The Developmental Engineering Utilization Field encompasses the design, development, installation, modification, service engineering, testing, and analyses of materials, techniques, methods systems, or processes. Each specialty includes responsibilities for management of programs, projects, and activities established to perform development engineering in that specialty.
AFSC 62E4, Staff Developmental Engineer, is normally limited to identification of staff or management positions where duties and responsibilities are specifically oriented for technical management of programs, projects, or activities, and where by reason of diversification of development, they cannot be specifically related to any one field of development engineering specialization. AFSC 62E4 is used only for those positions that specifically require general or multilateral development engineering specialization and in which technical management functions are primary importance.
AFSC 62E3E, Electrical/Electronic, AFSC 62E3H, Mechanical, AFSC 62E3B, Astronautical, and AFSC 62E3A, Aeronautical, are specialties in which developmental engineering management requires technical specialization and an academic degree in a particular specialty. AFSC 62E3G, Project, identifies project engineering or technical management functions that require an engineering degree but not in a particular specialty.
