The sampling technique uses saturated samples with 82 employees of PT. Kereta Api Indonesia DAOP 7 Madiun who in the position of junior supervisor, supervisor, senior supervisor, junior manager, manager, and senior manager/general manager/vice president of the office. The type of this research is quantitative. The statistical analysis used in this study was Partial Least Square (PLS) with the help of smart PLS 3.0 software. The results of this study indicate that proactive personality has a significant and positive effect on subjective career success; however, network and trust have no significant and positive impact against subjective career success. The results of this study show that the level of subjective career success at on the employees Indonesia's State-Owned Enterprises is fairly high. Employees who have high proactive personalities are proven to have high subjective career success, while the high and low networks and trust in this study have not been able to influence subjective career success. This research implies that it is important for companies to maintain a high proactive personality. Furthermore, companies need to use a great network and trust to make improvements to other aspects of the organization. Some previous studies about the influence of proactive personality and social capital toward career success have been carried out, but they are less specific on subjects that have satisfactory career paths. While the subject of this study is very significant, namely employees who are in the positions of junior supervisors, supervisors, senior supervisors, junior managers, managers, and senior managers/general managers/vice presidents, this will certainly be a reflection of the success of subjective career itself.
