The accelerating demands of engineering education in the 21st century, coupled with the emergence of artificial intelligence (AI), require a redefinition of the competencies of engineering educators. This study develops an integrated competency model tailored to the needs of modern engineering education. It synthesizes five established frameworks and incorporates recent research achievements on engineering teacher competencies. Through a detailed comparative analysis, this study refines a model that balances technical competence, pedagogical competence, and professional and ethical competence. The model is visually represented to highlight the interconnections between these domains. This study provides a foundation for improving faculty development and aligning teaching with industry and societal demands. It offers both theoretical insight and practical guidance for building educational excellence in engineering for a sustainable future.
