The objectives of this paper are to structure and discuss the main soft skills that have an impact on the employability in the Engineering field, aiming to fill the gap between education and job market in the STEM field. A systema- tized literature review on Humanities and Engineering Education of 2638 articles showed that the most important soft skills for the employability of engineers can be grouped into six main groups: Problem Solving and Crit- ical Thinking, Communication, Team Work, Ethical Perspective, Emotional Intelligence and Creative Thinking. The definition and relation between these skills and Engineering work are explored within the present work, concluding with a reflection about fresh graduate Engineers and their readiness for the job market.
