Job satisfaction is defined as the general attitude toward the job and the whole work situation (Furlan and Petz, 1992). The aim of this paper is to investigate how sociodemographic characteristics, personality traits, stress coping strategies, negative aspects of coding and workrelated flow explain job satisfaction. The following questionnaires were used: Work-related flow inventory (Bakker, 2008), Index of Job Satisfaction (Brayfield and Rothe, 1951), Coping Orientation to Problems Experience (Carver, Scheier and Weintraub, 1989), Big Five Inventory (Benet-Martinez and John, 1998) and two questionnaires were created for the purpose of this study - Sociodemographic Characteristics Questionnaire and Negative Aspects of Coding Questionnaire. This research involved 261 developers (nmale=216, nfemale=45). Pearson correlation coefficient shows that job satisfaction has a statistically significant positive correlation with problem-focused coping mechanism, extraversion, agreeableness, conscientiousness and flow, while job satisfaction has a statistically significant negative correlation with avoidance coping mechanism and neuroticism. Sociodemographic characteristics were not found to be statistically significantly correlated with job satisfaction. Hierarchical regression analyzes shows that extraversion, conscientiousness, neuroticism and flow are statistically significant predictors of job satisfaction, while Sociodemographic characteristics (sex, age, years of work experience, parenthood, living with someone and marital status), negative aspects of coding and coping mechanisms are not shown to be statistically significant predictors of job satisfaction.
