Dear Jill,
Engineering spans a huge spectrum of possible career options, some of which work directly with people, and others do not. For example, some engineers choose to work individually or in small groups to develop software, hardware, devices, structure designs, new materials, even new medicines. Others work directly with people to develop new prosthetics for people with walking disabilities, new robots that can help elderly in the home or fire fighters in the field, still others with architects to develop intelligent buildings. The best way to find out is to go visit different kinds of engineers at a local university.
Cheers,
Maja Mataric
