Boulder isn't that bad, isn't it only a 10-30% cut off base salary? The good strat is to get hired in MTV and then transfer to Boulder, your GSUs will still stay the same size. The better strat is to get hired in Zurich and then transfer, even bigger bonus!
Lower than in Bay/NYC, but still good, partially offset by the lower state tax rate, and (signing) RSUs aren't any lower than in the Bay, which means that take home pay for someone in Colorado after rent can be higher.
