Quote from my manager after a candidate turned down our offer: "We're not Google". This is responding to the candidate's "unreasonable" salary expectations.
So yes, I do believe there are companies paying significantly more.
Senior Software Engineers earn over 200k after bonus and stock: http://www.glassdoor.com/Salary/Google-Senior-Software-Engin...
Staff Software Engineers earn over 300k after bonus and stock: http://www.glassdoor.com/Salary/Google-Staff-Software-Engine...
This shows that while Google has "standard" base salaries, employees make a lot more through bonus and stock.
It is not uncommon for a very good engineer with 5+ years experience to earn above $400K / year (total = base + bonus (if issued) + stocks).
