I found this question which is similar but deals with moving to a position in another company.
I very recently received a sizable salary adjustment (about +15%) after I asked for it and made a case that I was underpaid for my contribution. A position opened in the same department but under another manager (i.e. another team) for whom I have worked for in the past. This manager asked if I was interested for this position and said that given my skills and experience the "conditions" (implying pay I am guessing) would be appropriate for a "senior person" he is looking for.
Would it appear greedy / would it be inappropriate to negotiate another higher salary given that this would be a lateral move (i.e. both positions are on the same pay scale) ?
