However, while researchers have explored work engagement and its predictors among various professionals, not enough has been done in the context of librarians in Edo State, Nigeria. In line with this, the study investigates the influence of subjective career success and job characteristics on employee engagement of librarians in universities in Edo State. The survey research design was used in this study. The population comprised one hundred and thirty-five (135) library personnel in tertiary institutions in Edo State. Data was collected through the use of a structured questionnaire. Data analysis was conducted using both inferential and descriptive statistics. The results showed a moderately high level of engagement among the respondents. It was also found that there is a highly positive perception of subjective career success and job characteristics among the respondents. The test of hypothesis shows that individually, subjective career success (Adj. R2 = 0.91; p = 001) and job characteristics (Adj. R2 = 0.425; p = 000) have significant influence on work engagement among librarians in Edo State. However, the multiple regression analysis to test the combined influence of both variables revealed that, while they have combined significant influence (Adj. R2 = 0.420 p = 000) only job characteristics account for majority of the influence (t; = 7.748; p = .000) compared to subjective career success (t; = 0.144; p = .885). The study concluded that job characteristics of librarian is a better predictor of work engagement. It was therefore recommended that it is important to strengthen managerial support for librarians in Edo State to boost their morale. Regular feedback and increased managerial backing will help librarians feel more supported in their roles.
