This is with 3 years of experience in Full Stack Web Dev SWE, and zero years in DevOps (but some basic experience with containers, cloud, and general linux server config).
I was hired as a Web App SWE, but was offered the chance to train in DevOps and took it, in order to grow additional skills. Full stack web apps are mostly CRUD. To learn the ecosystem around them... in terms of Cloud Computing, Kubernetes, and Customizing Containers... I consider that incredibly valuable.
My company needs DevOps but is having difficulty hiring for the role-- it's in high demand but low supply apparently. So, they're letting me become one of their interdisciplinary DevOps/Full Stack people.
I'm very happy as I am learning new things, working with a great team of enthusiastic, positive-attitude people, and upon my first promotion I imagine I'll make around $250k or so.
I don't know of many other professions where this is possible, while working 100% remotely.
