Introduction: The job motivation of university professors is a key factor in the quality of higher education, especially in academically demanding areas such as basic sciences in health sciences. Self Determination Theory allows for the analysis of motivation on a continuum ranging from demotivation to intrinsic motivation, including different forms of extrinsic motivation such as external regulation, introjected motivation, identified motivation, and integrated motivation. This study aims to understand the job motivation of basic science professors at a private university in Santiago during the year 2025, using Self Determination Theory as its theoretical framework. 

Results: A predominantly autonomous motivational profile was observed, characterized by high levels of intrinsic motivation and identified regulation, along with low levels of amotivation. Women showed slightly higher levels of autonomous motivation compared to men. Older teachers exhibited greater autonomous motivation. A positive and statistically significant correlation was identified between years of teaching experience and the dimensions of identified regulation and intrinsic motivation. 

Discussion: These findings are consistent with Self-Determination Theory and previous studies indicating that, with greater professional experience, teacher motivation tends to become more autonomous. The presence of autonomous motivational profiles is associated with greater well-being, institutional commitment, and more favorable pedagogical practices, which positively impacts student motivation. 

Conclusion: Basic science teachers predominantly exhibit autonomous motivation, with teaching experience standing out as a key factor in its strengthening. These results provide relevant evidence for the design of institutional strategies aimed at promoting teacher well-being and the quality of the educational process in higher education.
