What is the meaning of the job of an engineer?
Depends on the type of engineer. Originally, it meant one who
cared for, and operated engines- like a railroad locomotive. While
it still means that, there are other types of engineers. Civil
engineers design roads, bridges, dams, and large buildings.
Electrical engineers design electrical distribution and supply
systems. Chemical engineers design chemical manufacturing
processes. Military engineers may build bridges, destroy bridges,
place or clear minefields, build obstacles, etc.
