The evaluation system of international professional certification of engineering education highlights "achievement orientation", "ability index" and "student center", which puts forward new task for career planning education of engineering subject. Through the analysis of the employment situation of engineering students in recent years, it is concluded that career education should promote employment quality, develop career adaptability, improve core competences and knowledge, and match the characteristics of engineering disciplines. Based on the analysis of the status quo of the certification system and the employment situation, this paper critically analyzes the career education transformation under the background of international accreditation for engineering education from the three aspects:how to use the "competence indicators" to develop and promote 11 core capabilities; how to use "outcome driven" to help graduates improve career adaptability and manage career expectations; how to transform the curriculum of professional education under the under the background of international accreditation.
