I've held multiple titles doing this. Titles doesn't matter, because nobody respects what the titles implies.
Look for CloudOps, we often also have multiple certificates from Azure/AWS/DigitalOcean/Alibaba etc.
We not only keep infrastructure in code, but also make sure you are not ripped off by cloud provider and your architecture makes sense..
Maybe the next buzzword will be "platform engineer".
EDIT: Great explanation from one of the commenters https://link.medium.com/tC5p4nfYCib
Industry has moved on and if you need somebody to manage direction of your infrastructure (yes, be it just Jenkins or whole AWS) you will search for DevOps Engineer. There is no serious tier.
If you needed dedicated people so dev teams can just throw it over the fence to them that already existed and was just called sysadmins/ops. No need to invent a new term for that. More like some companies didn’t get the memo that devops != sysadmin, not even a title at all.

Well who’s in a bubble really?
My conclusion is DevOps is a newly made up word. The technology community is still trying to agree on a definition. Like all words, that definition will change over time.
I think it is okay to have your favorite definition, but I would be careful inferring too much about someone’s “seriousness” or competence based on their choice of favorite definition.
