I waited and learned it for a bit but nobody seems to be raising salaries for me to know that crap in addition to other full-stack stuff, so NO, there are DevOps engineers and they get good money for me not to deal with that garbage for essentially free.
Aye, none of the devs on my team want to deal with infrastructure - they want to push their code and have it go to production. I deal with all that garbage so they don’t have to.
I think the title “DevOps Engineer” is a bit of a misnomer, though; my team as a whole does DevOps, I build and maintain the platform.
I think team members do varying amount of DevOps but everyone should be involved. When writing code thinking about observability and monitoring, watching deploys as they go out, checking back on things randomly or intermittently whenever there's an inkling to do so, etc.
