Toyota Technical Center (TTC), a division of Toyota Motor Engineering & Manufacturing, North America Inc., announced April 5 that it will hire approximately 150 engineers, technicians, advanced researchers, and scientists by the end of 2012. TTC will add 100 additional jobs over the next five years to further advance engine and transmission development for the North American market. The majority of the new positions will be located at TTC's two Michigan facilities (in Ann Arbor and Saline) in the areas of powertrain, mechanical design, electrical engineering, electronics, and advanced research. The company's plans are subject to approval of state and local incentives. TTC currently employs more than 1100 people. In an unrelated announcement the same day, TTC said it has opened a "dedicated office" in California's Silicon Valley for research and development on in-vehicle infotainment systems.
