Google offer

Got an offer from Google, but seems they are low balling me. Current offer is 145 base / 15% bonus / 360 rsu - TC 256 No sign on bonus That is already after negotiating (still in progress) Initial offer was 140/15%/ 280 rsu + 20k sign-on - TC231 Location - Sunnyvale This is L5 for app eng. Current TC 230 - all cash. 14 YOE. Jersey City. Don’t have any competing offers, was not looking for new job. google had my CV for about 1.5 years and decided to proceed only now. Pretty comfortable on my current position. Several questions: 1) is there such significant difference in TC bw SWE and AE? Current offer seems to be like high L3 or low L4. 2) HR told that bonus could be more with good performance and that 80% of googlers exceeded expectations this year. How big could bonus be with good performance. 3) what TC could I expect in 2-3 years with good performance. Biggest decision factor for me is that I got an exception to work remotely from Florida keeping (most likely) same compensation. Google numbers can’t beat cost of living there. From other side - this is google. Your thoughts? Update: I am offered L4 position, not L5. I think I was interviewed for L5 (on of interviewers told me that), but after HC had to do another follow up interview. That’s why I think they leveled me as L4. Total comp looks now more in line with what L4 get. New question: HR told me that HC sees a lot of positive sign in fast promotion to next level. How soon it could possibly be for good performer? Update Feb 2019: Goldman raised my total comp to 270 (higher than google offer) and I relocated to Florida. It’s nice, warm and cheap here :)
