The career, engineer is strongly relates to us. The engineers involves a lot of fields, its type is varied also. The most common engineers we can see are structural engineer in building field, electronics engineer in the electronics field, software engineer in the computer field and flight engineer in the aircraft field. Similarly, among our parents is not lack of embarking on engineer. We can find that engineer is everywhere around us. Engineers have already become an essential part of the whole profession in the society. It promotes the development of society and economy, for humanity to create a better life.
Engineers are considerably impact on society. The scientist can study and discover the basic principle of the object, leading human to a new time. But how to practical use and implement thus principles are depend on the engineers. The problems always need to be solved by engineer. So we can see the foremost of engineers. To be more specific, for a mobile phone produce, engineers are attendance from design to marketing. In the produce, hardware and software engineer is responsible for the kernel design of the mobile phone. They decide the performance and configuration of this product. Moreover, engineers make the mobile smaller and smaller, the user guide interface become convenient and simplistic, avoid use the complicate operation. Also the attach function of mobile phone make it more powerful. Functions of camera and music player are arousing a new revolution of electronics. This is thanks largely to engineers. We just enjoy the fun and facility of the phone. Talk to the appearance of the mobile phone, mould engineers makes attracting outer skin. A good deal of consumer buys a mobile phone because of the eye-catching appearance. The consumer even though put away the practical applicability, replace by the eye-catching appearance. So the manufacturers are put more focus on the design of outer skin. Then some mobile phones has the same hardware configuration, but the outer skin has been change, also have a good market. Thus, the engineers’ power is so big. Then, sales engineer duty to management and planning of commodity regional sales of the produce. They understand their products’ advantages and disadvantages, persuading customers to use their own products. The sale engineers not only know a little technology but also realize the market trend and customer's psychology. Sale engineers create the huge sales for the products.
