Ask HN: How can I build up experience in ML infrastructure?

At the moment I do backend development in Go. In my free time I’ve been refreshing my C++ and doing some Nvidia cuda courses.

Once I’ve built up the fundamentals, how can I get some real experience (at least, enough to land a first job in the field)?

I might be going back to school as well for a mscs if I can get in somewhere. I figure that might help.
