With the advance of globalization, adopting a holistic perspective, involving the environmental, economic and social spheres is fundamental in the profile of professionals. To ensure employability in this context, it is essential to combine technical skills and Soft Skills (noncognitive skills). In view of this, this work aims to highlight the importance of teaching Professional Ethics in the Engineering course and identify which skills are required in the exercise of this profession. For this purpose, the methodology used corresponds to a systematic review of the literature, covering bibliometric analysis and content analysis, which extends the knowledge about Soft Skills (focusing on Professional Ethics) in the teaching and exercise of Engineering. Finally, the research discusses the results through a framework, classifying the Engineer's skills under environmental, economic, and social scopes. In this way, a holistic and integrative approach is presented, which is fundamental to achieve sustainable development and to ensure the employability of this professional.
