I can't find the "Programmers" site anywhere and haven't seen the "Software Engineering" site before - is it the replacement of "Programmers"?
It is the renamed and re-scoped Programmers, yes.
This happened after a lot of discussion about this within the site meta.
Given it has a new scope, if one is to ask a question there, I suggest reading their help center to see what's on topic before posting.
See here for a full list of past renames across Stack Exchange.
