With the erosion of lifelong employment concepts, individuals seek to enhance their competitiveness for employment maintenance and satisfactory career management. Science and technology professionals also pursue capability development for career success, improved performance, and fulfilling careers. This study applies career capital—comprising meaning competency, technical competency, and relational competency—to science and technology professionals, examining relationships between career capital levels, subjective career success, and performance. We analyzed survey responses from 1,936 employed science and technology professionals from the 2022 Science and Technology Human Resource Development Panel Data. Results confirmed that all career capital components had significant positive effects on subjective career success (employability and career satisfaction). Meaning competency had the largest impact on subjective career success, while technical competency most strongly influenced job performance, followed by meaning and relational competencies. Employability showed greater impact on job performance than career satisfaction. Mediation analysis revealed that all three competencies positively affected job performance through subjective career success. These findings demonstrate that career capital positively influences both subjective career success and performance, indicating the need for balanced career management support that enhances all three competencies for science and technology professionals.
