The purpose of this study was to systematically review the existing literature on the impact of work engagement on job performance. One objective was to examine work engagement and job performance definitions to develop working definitions for both concepts. The primary objective was to investigate gaps using a research gap classification model. Accordingly, key studies regarding the impact of work engagement on job performance were meticulously examined through a systematic literature review with a meta-analysis, which involved investigating research gaps. The study referred to databases such as Google Scholar and ResearchGate to examine the impact of work engagement on job performance, focusing on publications from 2013 to 2023. Initially, 33 documents were referred and only 16 were left after screening as the sample. Tables and graphs were utilized to synthesize research gaps across various domains. According to the gap’s classification model, four types were investigated; empirical gap, knowledge gap, methodological gap, and population gap. This study systematically identified and classified research gaps, providing a platform for future investigations that enhance existing knowledge. Considering the limitations of the study, several directions for future research are suggested
