1. The role of foreign CTO depends not only on the scale of the company, but also on the development model of high-tech enterprises. Many founders of Silicon Valley companies are from technical backgrounds, but they don't want to be technical team managers when they grow up. Therefore, in addition to hiring a professional manager as CEO from outside, you can also hire a VP in charge of R&D management, so that the founder can define himself as CTO, so as to get rid of the trivial matters of management and concentrate on the research of technology trends. For example, Sergey Brin, one of the founders of Google, is in charge of researching technology trends.

2. Domestic CTO pays more attention to R&D management, and CTO is responsible for managing all resources related to development and completing the project on time. On the other hand, it is similar to the role of chief engineer. As an authority on technology, it is necessary to conduct some research and discussion on the next technical development direction of the company, make judgments and help the CEO make decisions.

Domestic companies are still exploring the scope of responsibilities of CTO. The responsibilities of this position are closely related to the company's current needs and staffing. For small and medium-sized companies, the job requirements of CTO are also vague, which is more common in China.
