The Faculty of Engineering, Assumption University was established in 1990 with two pioneering departments, the Department of Electrical Engineering and the Department of Electronics Engineering. The Department of Computer Engineering was included in 1991. In 1998, foreseeing more demand for engineers in telecommunications industry, the Faculty set up the Department of Telecommunications Engineering. All four departments offer Bachelor of Engineering degrees in their associated fields. 

            Having consolidated the undergraduate programs, the Faculty launched its first graduate program, the Master of Engineering in Broadband Telecommunications in 1997. After the success of the first graduate program, the Faculty introduced two additional graduate programs in 1998 namely, the Master of Engineering in Telecommunication Management and the Master of Engineering in Power Electronics (currently the Master of Engineering in Industrial Automation and Power Electronics). These graduate programs are focused on advanced studies and in-depth research in their associated fields.

            In 2003, anticipating the industrial need of engineers in multi-related areas, the Faculty merged its four original undergraduate departments to form three new departments. They are the Department of Electrical and Electronics Engineering, the Department of Computer and Network Engineering, and the Department of Telecommunication and Electronics Engineering. In mid of 2006, the Faculty launched a new and exciting undergraduate program in Mechatronics Engineering, which involves interdisciplinary fields of study including Mechanics, Electronics, and Computer Engineering.

            The first class of Assumption University engineers has graduated and served the society successfully since 1994. Until now, there are more than one thousand engineering graduates.
