What are the differences in career options between Engineering and Physics?

Disclaimer: the following answer is given from the perspective of a physicist. According to dictionaries, engineering involves the application of existing knowledge from mathematics and the natural sciences to solve practical problems related to structures, machines, products, systems and processes. Work that falls under the category of applied physics is much closer to engineering than to theoretical physics, for example. It is relatively easy to make the transition from physics to any of several branches of engineering. Many physicists who take employment in industry are in fact doing work that their employers classify as engineering, and physicists are routinely hired for positions that are advertised as being in the area of engineering. People trained as engineers greatly outnumber those trained as physicists.
