As fast-track individuals with special knowledge and expertise, engineers have great expectations and ambitions for their careers and are known for striving for psychological success and climbing the career ladder. Nevertheless, several factors have influenced the well-being of engineers, including conflicts between personal goals and expectations with available advancement opportunities, work autonomy, and work demand. As a result, engineers in Malaysia are considered to be unhappy workers. This scenario will likely worsen if little attention is given to researching the engineer's individual well-being. Thus, it is appropriate to conduct a study that assesses the level of individual well-being among Malaysian engineers using career goal development as a predictor. This study applied a self-administered questionnaire to collect data. A total of 500 questions were distributed to registered professional engineers, and 387 completed questionnaires were returned for analysis. The measures used in the study were adopted from previous studies with acceptable reliabilities, and the research hypotheses were investigated through correlation and path analysis using PLS. The research findings have provided useful information on the positive influence of protean career orientation on psychological wellbeing. Furthermore, the results showed that career goal development has a positive influence on individual well-being. The implications of these findings contribute to the understanding of the process through which career attitude affects individual well-being, which will be discussed.
