Employee job engagement has received a lot of attention since it's important for a company's efficiency and performance. The purpose of this study is to investigate the mediating role of person-job fit in the relationship between transformational leadership and employee job engagement. The findings of this study show that both transformational leadership and person-job fit impact job engagement. Data were collected using self-reported surveys from 193 full-time employees working in the healthcare sector in Makkah Province, Saudi Arabia, as well as analyzed using the Partial Least Squares technique. Furthermore, the findings suggest that the relationship between transformational leadership and job engagement is mediated in part by person-job fit. These findings suggest that transformational leaders improve employee perceptions of person-job fit, hence increasing job engagement. Implications, limitations, and future research directions are discussed.
