Is there a standard job title/career path of someone who specializing in solving low level performance and diagnostic problems?

In particular for a windows context I mean things like understanding dump files, using windbg, perfview, sysinternals tools, analyzing run away processes, etc.

A lot of these low level tools seem to go together and many performance problems seem to be a type of diagnostic problem. It also seems to require some specialization and talent. I was curious if there was a recognized career path working with tools like these.
