The goal of this research is to look into the link between job happiness and work engagement. The goal of the study was to look into the relationship between (equal opportunities, personal influence, nature of career, development opportunity, employee recognition, work challenge, supervisor behavior, ethics and integrity, and job empowerment) and job satisfaction in Erbil's private companies. In order to examine the association between work engagement and job satisfaction, the researcher employed a quantitative research method, but only 108 people took part in the current study. To assess the association between variables, the researcher employed multiple regression analysis. The researcher discovered that among the other work engagement aspects, workplace challenge had the greatest value =.671 and P-value =.000, indicating that many employees in private organizations are engaged to their jobs due to time management, overburdening tasks, and communication. This study emphasized the importance of workplace challenges in motivating employees to become more involved in their organizations. Employee engagement is defined as a good attitude toward work and the degree to which an individual is committed to the company. Only a small number of employees from private enterprises in Kurdistan took part in this survey, which limits the study's findings.
