I'm involved in a few different areas at my company, but when I get involved in hiring DevOps types, I try to look for the person you described as a "Platform Engineer." There are far too many times where I talk to people who know what tools are, but its just a black box that they plug things into, and they only know to use it because that's what someone at their local DevOps meetup group said was cool/useful. I want people who can help devs, not just deploy their code, or give them a system to run on. They shouldn't be afraid of learning a new language (or just looking at it), and should have competency in one already.
