Hi,
the 'description' tag is fine (although nobody used 'description:subject' before, but 'subject:description' is used a dozen times and might be a better choice)

I referred to the 5 translated "person:job" tags (also used nowhere else). 

- in general, translations should not be tagged - simple things like this can be translated automatically very well
- "job" is a rather modern word, something like "profession" seems to be a better fit for a person with a memorial.
- I'd prefer this kind of information within the description and not with its own tag - it's very unlikely that there will be more than a few of these around the world. 
- In general we should have a wikidata or wikipedia link for the subjects where all information can be retrieved easily
