The bigger the company the less impressive "senior" is. There are probably three levels of staff above it and then distinguished super fellow territory.

A senior software engineer can easily make $300-400K+ at BigTech that’s “impressive” enough to me.

On the other hand, a “senior” working at a bank or other large non tech company will probably be making less than $175K if you aren’t working on the west coast.

For instance Delta
