Engineering education is perceived to be a tough field of study with detrimental effects on the mental health of undergraduate engineering students. High levels of anxiety and depression are reported among this population. Overall, mental health research is often biased toward looking at mental health from a deficit perspective and investigating mental health as a negative phenomenon. This trend also persists in engineering education research. The purpose of this exploratory study, therefore, is to investigate the condition of subjective wellbeing (SWB) of undergraduate engineering students to understand the factors that they perceive as positively contributing to their overall wellbeing in an engineering college environment. Qualitative data from eight undergraduate engineering students interviewed in fall 2021 in the college of engineering at a land grant public institution in the western USA were thematically analyzed. The resulting 11 themes were then re-grouped and conceptualized into 7 factors (faculty support, learning experiences, support environment, financial support, engineering practice opportunities, task organization, and task orientation) for clear mapping, understanding, and explanation. The outcomes from this research have positive implications for the SWB of undergraduate engineering students, with support from their educational institutions.
