Because job satisfaction plays a crucial role in teacher attrition, numerous scholars have investigated the predictive variables for occupational well-being in educational contexts. However, this research area has been relatively ignored in higher education contexts. To fill this lacuna, this research employed an explanatory sequential mixed-methods design to examine the predictive roles of teacher mindfulness and self-efficacy in impacting the job satisfaction of English instructors in various Iranian universities. In the quantitative phase, data from 226 EFL instructors were analyzed following a rigorous screening of an initial pool of 234 participants who completed measures of the focal constructs. Structural equation modeling (SEM) confirmed that teacher mindfulness and self-efficacy significantly predicted job satisfaction, with self-efficacy emerging as the strongest predictor. Furthermore, mindfulness exerted a significant indirect effect on satisfaction through the mediation of selfefficacy. In the subsequent qualitative phase, follow-up semi-structured interviews were conducted with a purposive subsample of 12 instructors to clarify the mechanisms underlying these statistical paths. Thematic analysis revealed that mindfulness facilitates a "psychological pause" through affective detachment, while self-efficacy provides the pedagogical agency necessary to maintain value-action congruence despite institutional stressors. These results suggest that mindfulness acts as a cognitive precursor that enhances pedagogical presence and professional resilience. The implications for developing targeted onboarding strategies and mindfulness-based interventions in higher education are discussed
