As a language expert with a deep understanding of grammar and usage, I can provide a comprehensive answer to your question regarding the capitalization of job titles.
Proper nouns are words that designate a particular person, place, organization, or thing and are typically capitalized in English. They are distinct from common nouns, which are general terms for categories of people, places, or things and are not capitalized unless they appear at the beginning of a sentence or are part of a title or name.
When it comes to job titles, the rules for capitalization can be a bit more nuanced. In general, job titles are considered common nouns and are not capitalized in English unless they are part of a name or title that is itself a proper noun. For example, you would not capitalize "manager," "engineer," or "teacher" when they are used in a general sense. However, if a job title is part of a proper name or refers to a specific, unique position, it should be capitalized.
Here are some examples to illustrate the point:

1. Proper Noun as a Job Title: "President of the United States" is a proper noun because it refers to a specific, unique position. Therefore, it is capitalized.

2. Common Noun as a Job Title: "president" as a job title for a company or organization is not a proper noun and would not be capitalized unless it is part of a proper name, such as "President John Smith" of XYZ Corporation.

3. Unique Position as a Proper Noun: As mentioned in your reference, "Queen of England" is a unique position and is capitalized because it is a proper noun.

4. General Job Title: "Manager" would not be capitalized when used in a general sense, such as "The manager will see you now," unless it is at the beginning of a sentence or part of a proper name.

5. Job Title as Part of a Proper Name: "Vice President of Sales" would be capitalized if it is part of a proper name, such as "Vice President of Sales Jane Doe."
It is important to note that there can be variations in capitalization practices depending on the context and the style guide being followed. For instance, some style guides may recommend capitalizing job titles when they are used directly before a person's name, while others may not. Additionally, in legal documents or formal correspondence, job titles might be capitalized more frequently to show respect or to distinguish the individual's role.
In conclusion, whether a job title is capitalized depends on whether it is a proper noun that refers to a specific, unique position or if it is a common noun used in a general sense. Proper nouns are capitalized, while common nouns are not, unless they are part of a proper name or appear at the beginning of a sentence.
