Uplift is a term used to indicate an increase in salary or package. Say if you will be igned from a current location to a remote one, they usually include in the new package or you should demand for an "uplift" which ranges from 30 - 40% increase from your base salary exclusive of allowances, accomodation, transport, etc.
