Abstract: In the rapidly changing modern workplace, it is extremely important for companies looking to recruit, retain, and inspire people to have a thorough awareness of the elements influencing modern workers' job satisfaction, especially in the IT sector. In an effort to better understand the complexities of modern workplaces, this research study examines the intricate interactions among work-life balance, employee engagement, and job satisfaction. Research gaps were found using an extensive evaluation of the literature, which prompted the development of research hypotheses. Data was gathered through secondary data analysis and questionnaire surveys using a quantitative research technique. The results showed a strong relationship between job satisfaction and staff engagement, highlighting the value of encouraging employee involvement to raise overall job satisfaction. Even though there was less of a correlation, there was still a favourable association between work-life balance and job satisfaction, demonstrating the significance of encouraging a good balance between work and personal duties. Theoretical implications emphasised the importance of work-life balance and employee engagement in fostering both organisational success and employee well-being, and they highlighted the role that job satisfaction plays in organisational wellbeing. The insights gained from managerial implications included customised employee engagement plans, adaptable work schedules, resource allocation for employee assistance, and the encouragement of inclusivity and diversity in the workplace. Despite many drawbacks, including possible self-reporting biases and the cross-sectional design, this study offers insightful information about the variables affecting job satisfaction in contemporary settings. Organisations can establish work cultures that promote employee satisfaction, productivity, and long-term success by placing a high priority on employee engagement, promoting work-life balance, and valuing diversity and inclusion.
