As mentioned platform architect. I work on the research, design and construction of PaaS systems (which usually include SaaS as well, the backend of what lambdas or "functions" etc run on).

Not the person you asked, but I needed a place to run my shitty python scripts and the minimal requirement in my org was 'stand up an ec2 and get the OS managed by (insert other team)'
I complained about it and designed and built an MVP for a k8s SaaS in a week or so and pitched it to leadership and got some buy-in.
