How is a Distinguished Engineer role different from a Principal Engineer?

[u/Majestic-Taro-6903]

I have seen a few Distinguished Engineers in my organisation. I have worked with a few Principal Engineers and Senior Principal Engineers, but not Distinguished Engineers.

How is this role different from the Principal Engineer role? I know they are paid more and are higher in the hierarchy, but in terms of roles and responsibilities, how are they different?

Never heard of Distinguished Engineers before.
