'prominent engineer' makes it sound like the prominence is due to being well-respected for skill in engineering, when it's apparently not. This is what ehutch79 is saying.

As an example, my primary role in my company is administration of systems. I very rarely take out the trash, and sometimes refill the toilet rolls if they're low. It would be misleading to refer to me as a janitor, prominent or otherwise.

Edit: I say 'apparently not' because she may be an awesome engineer, but her code is in private repos.
