UTA (Overseas Branch)

Since 2001, Ultimate Technologies Asia (UTA) Sdn. Bhd, our overseas affiliate, has stood at the heart of Malaysia's capital Kuala Lumpur. The branch has sustained its progress as a Multimedia Super Corridor (MSC company, a concept promoted by the national government.
    Meanwhile, UTA maintains its local presence, attracting some of the brightest minds in Malaysia with undergraduate and graduate education in electrical and electronics engineering. Since its establishment, the branch has complemented UTI's PCB design with its advanced electromagnetic field simulators.
    As the local staff are fluent in both English and Chinese (Cantonese and Mandarin), they provide technical support, material procurement, and high quality information to clients operating in East Asia.

The Multimedia Super Corridor (MSC) status guarantees preferential treatment to enterprises whose aims and activities align with those of the national government: promoting Malaysia's Digital Economy. While Japanese companies comprise less than 1% of the overall participation in this public endeavor, it provides a platform for critical partnerships to emerge between the over 200 companies involved from Asia, Europe, and the United States.
    There is, moreover, a large portion of Malaysia's intellectual workforce that aspires to work at MSC companies. Coupled with the government's employee referal system, this honorable status empowers us with the ability to build a high-quality team.
