I am a former Sr. Systems Administrator, and Sr. Systems Engineer. My current title is Sr. Devops Engineer.
Pretty much everybody who knows their way around a compiler and administers systems could probably take this title and be fine, and then you're not suffering under the yoke of devops or whatever. Because when I hear "developer," I can't help but think a feature engineer on the product side for some reason. Same with that word creeping into "devops," and that leads to things like "full stack" engineering -- creating the impression that only a select few work with or consider "the whole stack," which is a scary subliminal message. Even if you're a developer simply changing the colors on the Facebook feed or something, you should always be thinking about the full scope of things and how your changes will be operated. (Your operations nerds will love you if you think about us ahead of time.)
As an aside, systems administrator with no software skills is a totally and completely fine career, with a number of very smart people (and friends, still proudly announcing every year of uptime in texts), and in a lot of these discussions I see them denigrated. Just remember that, not saying anyone is doing it.
