The shift towards hybrid working arrangements – a blend of office-based and remote work – has become a distinguishing characteristic of the post-pandemic Information Technology (IT) sector. The purpose of this study was to determine the impact of hybrid work arrangements on employee engagement and the mediation of work-life balance among employees working under hybrid work arrangements in the Information Technology (IT) sector. A quantitative research approach with a descriptive research design was adopted. Primary data were collected through a questionnaire using a five-point Likert scale to measure Hybrid Work Arrangements, Work-Life Balance, and Employee Engagement. A total of 222 valid responses were received using convenience sampling from employees with experience of hybrid work. The collected data were analysed using reliability analysis, descriptive statistics, Pearson correlation analysis, and regression analysis. The reliability results showed excellent internal consistency across the study variables (Cronbach's Alpha = 0.940). The correlation analysis showed positive and statistically significant relationships among Hybrid Work Arrangements, Work-Life Balance, and Employee Engagement at the 0.001 significance level. The regression model was statistically significant (F = 136.013, p < 0.001), and Employee Engagement showed a significant positive effect (β = 0.618, p < 0.001). The findings suggest organisations should continue to strengthen hybrid work policies while giving particular emphasis to employees' work-life balance, communication, and managerial support.
