Earlier quoted context omitted.
I'm not a compiler engineer, but I'm willing to venture that the lower bounds of a "competitive salary" for an engineer in silicon valley is somewhere between 200 & 250k. Compiler engineers may make much more, I don't know, but it's unlikely they make less than that. Perhaps that answers your question?
> an engineer in silicon valley Good point. The biggest factor that determines an engineer's salary is location, followed by years of experience. Not whether they work on compilers/embedded/web/whatever.
Not true! See: salaries for people who know kdb+, that embedded engineers almost always get screwed on comp.
