<p>The rapid development of STARA (Smart Technology, Artificial Intelligence, Robotics, and Algorithms) technologies is reshaping the labor market, requiring more proactive and responsible job-seeking behavior. Based on the Theory of Planned Behavior (TPB) and Social Cognitive Career Theory (SCCT), this study builds an integrated model to analyze the impact of STARA awareness on responsible job-seeking behavior, while examining the mediating role of career decidedness and the moderating role of generational differences (Gen Y and Gen Z). A quantitative survey was conducted with 400 employees in Vietnam; data was processed through SPSS to test reliability (Cronbach’s Alpha), exploratory factor analysis (EFA) and correlation, followed by structural equation modeling (SEM) on AMOS to test the hypotheses. The results show that STARA awareness positively affects responsible job-seeking behavior, in which career decidedness plays a prominent mediating role. However, generational factors do not moderate this relationship. This may be due to the fact that both generations are growing up in the same context of strong digitalization, leading to similar perceptions of professional responsibility in the face of technological impact. The study contributes to clarifying the mechanism of ethical career behavior in the digital transformation era, and provides useful suggestions for vocational education, public policy, and human resource management.</p>
