Don't capitalize job titles like manager, director, and chairman when they are used descriptively beside a name (i.e., when used in apposition).

Should job titles be Capitalised in a sentence?

Job titles are normally capitalised when they stand in for (or are part of) a proper name, especially when the title precedes a person's name. ... When used generically or descriptively, job titles are not usually capitalised.

Are positions capitalized?

We do not capitalize the title/rank/position of a person when it follows the individual's name; when it used with the name of a company, an agency, an office, and the like; or when it is used alone. In other words, a title/rank/position is a common noun or adjective unless it immediately precedes a person's name.
