I go a step beyond. When I’m interacting with “non-IT” folks, I say just I’m “in IT”.

It isn’t a problem for my ego to do that, and it’s something that’s both relatable and typically stops the conversation from revealing anymore about my work (not that there’s really anything to hide, I just enjoy my privacy and no, I don’t want to meet your “computer genius” nephew or fix your phone).

If I’m in a clearly technical group, I’ll go into more detail. I don’t identify myself with the DevOps term though, or sysadmin, or developer. I don’t clearly fit into any of the -currently assumed- definitions of those.
