So I went to university on a general computer science course, so this might already discount this answer. However, during my final year, a friend who was already in the industry convinced me to push towards a cloud engineering role (systems engineering specifically with cloud services like Amazon and Azure). This was not something my course covered at all, so we went through containers, AWS, Terraform, Kubernetes etc. during our free time before he got me an interview for a junior role when I graduated. I was very lucky with my circumstances but I don't think I would've gotten the role without that extra study.

These roles are in demand and will be for the foreseeable future. If you have general Linux knowledge then you should be able to pick it up fairly quickly.
