It's normally considered a bad salary in comparison to what you could be making. I won't speak for the poster but I left a ~$1m / year TC job ($300k base the rest RSUs) to join a startup.

The easiest way is to move to the SF area. However, you'll end up spending most of the after-tax pay on housing, food, etc. For example, rent on a 1 bedroom apartment in the suburbs is going to be $30-60K per year:
If you live in the US and work as a software engineer at a top tech company it’s very straightforward to make more than 200k. Otherwise, it’s much harder.
