The urgency of this study arises from the need to enhance job satisfaction among employees in higher education institutions in order to align with the demands of Sustainable Development Goals (SDGs) 4 (Quality Education) and 8 (Decent Work and Economic Growth) within the higher education sector.Methodology: A quantitative approach with an associative causal research design was employed. Data were collected using a survey method with a questionnaire instrument. Data analysis was carried out using Partial Least Squares–Structural Equation Modeling (PLS-SEM).Finding: The findings demonstrate that internal communication and career sustainability positively influence both work motivation and job satisfaction. Moreover, work motivation is proven to act as a partial mediator, further amplifying the effect of internal communication and career sustainability on job satisfaction.Conclusion: These findings not only contribute theoretically by enriching the model intervariable relationships in the education sector context but also offer practical implications. This study recommends improving the effectiveness of internal communication and developing sustainable career programs as essential strategies for enhancing employee work motivation, which is ultimately serves as a crucial factor in improving job satisfaction in the Mercu Buana University environment.]]>
