TuSimple is planning a major reduction in headcount which could affect at least 50% of its staff as the self-driving truck startup looks to reduce administrative costs after years of losses and setbacks in perfecting its autonomous driving systems, according to a Saturday report by The Wall Street Journal. The company, which had a total of 1,430 employees globally as of June, will scale back its testing efforts with a significantly downsized operation in Tucson, Arizona, and sharpen its focus on software products tailor-made for carriers, the report said. The job cuts follow a recent management reshuffle where Hou Xiaodi, the company’s former chief executive and co-founder, fired TuSimple’s board with the help of fellow co-founder Chen Mo last month.
