Google for "occupation iq" readily finds many surveys of different occupations with a fairly expected correlation: Professors and scientists on the high end of the spectrum and laborers on the other. Software engineers/CS isn't at the top but tends to rank fairly highly. However, narrowing these stats to a single person as meaning "if you have a low IQ you can't be a good engineer" is incorrect, as that is totally throwing out: 1) IQ being only a single of many factors (reading about this from people in the field, I often hear IQ cited as the best single predictor we have, but still only accounting for ~30%) 2) IQ can change 3) IQ doesn't include domain knowledge, determination, or any other factors particular to a specific occupation.
