This study examines the crucial role of English proficiency in engineering careers, specifically within multinational corporations, addressing disparities between industry expectations and graduates' language skills in non-native English-speaking countries. It aims to bridge this gap by aligning engineering English courses with international job market demands. Focusing on leading Thai companies with global headquarters, the investigation employs various techniques, including interviews, the index of item-objective congruence, the analytic hierarchy process, the analysis of variance, the Wilcoxon signed-ranks test, and a matrix plot. The comprehensive gap analysis highlights verbal communication skills as highly valued by engineering firms, emphasising adjustments in English curricula towards listening and speaking skills, with reading and writing skills constituting a smaller portion. Cross-regional consistency in skill importance is confirmed, facilitating generalisable conclusions. The research underlines the necessity for universities to improve students' abilities in technical conversations, presentations, and negotiations through tailored lesson plans aligned with industry requirements.
