There is an intuitive relationship between the creation of engineering careers and the social innovation in any country. In the global scenery a nationâ€™s economy is the main driver of its social innovation. As in all countries, engineering careers in Mexico have always been closely related to the economic activity through the assimilation, operation and maintenance of the technological platforms used by the nationâ€™s public and private organizations to perform their operations. Technological change has been a major factor influencing engineering education in last decade provoking that Mexican engineers needed to expand their actuation areas to attend more than just the industryâ€™s operative needs. Today Mexican engineers are also involved in research and development innovation projects. Through an investigation of the history of the creation and evolution of the engineering careers based in the available data of the Facultad de Ingenieria (FI) de la Universidad Nacional Autonoma de Mexico (UNAM), in this paper we intend to show that in the country engineering careers and professionals always have had a relevant actuation in its development and have been behind the economic and social innovation processes.
