I'm looking for work again, after the most recent temporary thing came to an end. (Arguably I did it all too quickly!).

Apart from the challenge of persuading myself that I'm actually good enough to do _any_ described job, I find I haven't a clue what job titles mean these days. Cambridge University hides everything under a "Computer Officer" blanket, and I know I'm a system administrator (who does networks and other stuff too), but the job market is full of "Thing Analyst" and "Site Reliability Engineer" and "DevOps" and I haven't a clear idea what boxes if any I fit into.
