levels fyi shows for IC Amazon L7 same as Google L6 but for SDM Amazon L7 same as Google L7. At Google L7 IC TC is comparable to L7 SDM. does that mean at Amazon L7 IC has a TC same as L6 SDM?
SDM is at least 5-10% more than IC at any point in the range. I believe gap is wider at bottom of band but then narrows at the top.
levels.fyi describes career equivalency/mobility levels. So an L7 SDE is likely to move to Google as an L6 SDE, and an L7 Sr. SDM is likely to move to Google as an L7 engineering manager. This doesn't mean TC is equal between L6 SDM and L7 SDE. They are not. PE comp band is quite a bit higher than L6 SDM (PE is approximately 450-700 vs. 320-450 for L6 SDM in the Bay Area, for example).
I believe L6 SDM are paid slightly more than L6 SWE, on an average.
