Not in common usage within the US tech industry (by this I mean technology-first companies, not just companies who happen to have some developers). In those companies at least, if you say you want to get into "IT" people are going to think you mean tech support, system administration (generally for internal systems), etc. I don't know any professional software developer in one of these companies who would say they are "in IT." (Yes, it's a huge industry and I'm sure you can point out exceptions.)
