The article deals with the historical and philosophical analysis of the “professional mobility” concept in the context of would-be computer engineers training. The growth and complexity of social, economic and professional information is described to require engineer-teachers quickly update their knowledge, be successful and necessary, ready for any changes in professional activity, be able to adapt quickly and effectively to new conditions of the labor market – that means to be mobile. The concept of the professional mobility field, which shows definitions (profession, professionalism, mobility and others), adding the studied concept with common meaning, purpose and functional similarity, is outlined. They determine the formation of professional mobility of computer engineers-educators, allow to understand more its essence and to define ways of its development in the conditions of university education. Historical, philosophical, and pedagogical approaches to defining the phenomenon of occupational mobility in the light of would-be computer engineer educators training have been considered. It has been found that today mobility is determined not only from the standpoint of social philosophy and sociology, but also in economic, psychological and pedagogical aspects. Professional mobility is proved to be determined by the social attitudes, orders, values, goals and other motivational factors that really determine the behavior of a subject in society. It is closely linked to, caused by, and influenced by social change. In shaping the professional mobility of the would-be engineer-teachers in the field of computer technology, attention is paid to the need to analyze the qualitative side of this phenomenon, the study of value aspirations and the system of personally meaningful characteristics of the would-be specialist, which will allow realizing themselves successfully in various forms of interaction and self-development. Key words: professional education, mobility, professional mobility, computer engineer educators, would-be computer engineers training.
