For this person I would advise working against any company that isn't a software/tech company (or, at the very least, that doesn't have the development of software as a line of business or as the primary means of support for their revenue driving activities). These organizations--governments, schools, and hospitals--aren't "tech companies". Their cultures are generally the opposite of what a person interested in technical challenges in software would want. They're places where "playing it safe" and "playing politics" are far more important than writing software.
