Data Engineer V/S Data Analyst Lead @Facebook and Salary

How is Data Engineer V/S Data Analyst Lead position @ Facebook and how much is the salary range for IC-5 both roles? I am targeting Amazon's L6 DE equivalent position at Facebook. Will Data Analyst Lead IC-5 @Facebook should be good or I should instead target IC-6 position OR Data Engineer IC-5/6? I am targeting to make 240K in Seattle area, should 300K be good to ask in Menlo Park for IC level 5? OR should I rather stay in Seattle if I can score 230-240K here? #Facebook #Amazon #MenloPark #Seattle #DataEngineer #DataAnalyst
