Well there are a lot of companies that currently hire only the best of the best. Try working at companies that have notoriously difficult interviews. I've heard MemSQL, Dropbox, Jane street capital, D.E.Shaw and Palantir are a few of them. These companies tend to hire more competitive programmers (top coder, ICPC etc), who usually have very high IQ. Now, these may not be the best all-round developers but they'll definitely be among the smartest.
