Examples of how the words change meaning with context and an article: My job (place of employment) is in New York.
My boss told me she has a job (task) for me. I told him, " My job isn't fun." He told me, "That's why they call it work."

“Job” is a noun. It is a mental or physical activity that an individual performs in exchange for a fee or payment. It is a formal type of work/employment, occupation, profession, career, or trade.

I like my teaching job at the university.
I wish I had a full-time job.
I have to work three jobs just to pay my bills.
I’m looking for a job in the computer field. Are they hiring at your company?

“Job” also refers to a specific task.

My job is to wash dishes; your job is to dry them.
You did a good job mowing the lawn.
The job of cleaning houses is exhausting.

“Work” is used as a noun and a verb.
As a noun, “work” is the physical or mental activity that is performed with the purpose of receiving money or accomplishing or producing something.

What kind of work do you do?
Where do you work?
I’m looking for work in the teaching field.
I have a lot of work to do.

As a verb, “work” is the action of performing a mental or physical activity.

I like working in this profession.
I have worked here for almost 25 years.
I work very hard for my money.
I work a lot of Sundays.

“Work” is also a place where the act of working is done.

This is where I work.
I come home from work every day very tired.
What do you do at work all day?

In very general and simplistic terms, “job” is the position, and “work” is all the things you do in that position (job).

Muchas gracias a ambos. La parte en rojo me encanaló un poco más.
