"Damon Horowitz ... has two jobs at Google: director of engineering and in-house philosopher"

I read that here.

Your first thought might be that, just as 'engineering' at Google presumably has a different meaning from engineering in the 'connecting bits of steel' sense, 'philosopher' probably has a different meaning too. But banish such thoughts - he has a PhD in philosophy and the article is about studying the greats (if not Greats).
