take the info im going to post in quotes and write a short, but sweet cover letter for this job. "We need a person who can understand context and situations for different type of jokes. Once you understand the "joke" from the text we give you. You will visually explain what is needed in the image with your own words.   

WHAT IS A GHOST Writer/DESIGNER?
A Ghostwriter, is a person who is not able to say that "they" wrote this piece. Just as with "ghost writer" a "ghost designer" (or a storyboarder) is a person who are not able to put their signature on their design. 

What type of cartoons/images is going to be made ?
The images is meant to go viral on social media. And the type of images are typical the dirty once. Other types of images also be typical "situational", for example: where you are playing hide and seek with a dog. And you can see the dogs tail wagging behind the curtain.

So its important that you understand what kind of elements you need to add. So the reader visually understands the joke visually. And without the image being cluttered with too many other elements in the image that matter to the joke. I also think its essential that you also know how to add micro expressions. 

I will provide you with the text, and the "thoughts that makes this funny". And you (the person who applies to this position). Will add the details that is needed in order to get the outcome I want.

Examples of different type of images is: 

EXAMPLE 1:
Image: A "snobbish diva" poodle in a luxury dog bed, wearing a diamond-encrusted collar, speaking to a mutt (a mixed dog breed) sleeping on a rug, saying:

"Look, darling! Not everyone can be a purebred."

Explanation: The humor in this meme comes from the snobbish poodle acting like high-class society, with the twist being that they're both just dogs.

Here is another example that is not "typical" dirty. That has another type of humor to it.

EXAMPLE2: 
Image: An obese labrador dog looking at his empty food bowl, then up at the oblivious human on their phone.

Caption reads: When you're on day 1 of your diet. But your human hasn't gotten the memo.

Explanation: This meme subtly pokes fun at dieting while capitalizing on a dog's unending appetite and the human's obliviousness to their dog's "diet" plans.

Other types of images I also need the same type of "explaining" text to is images to articles or images to ebooks. In these types of images you will just explain in details elements of the details in the text I have. The details you add will help the image designer to visually help the reader.     

A "target miss" could be when the designer dont have enough information of the context. Meaning if you clutter too many elements around the joke that makes the reader confused on what to look at. In that way I will most likely never get the ouctome I want. If you are serious about application for this position. Please start your application with your favorite animal. 

I will get in touch with you if you looks interested to be working with. And I will show you a bit more indepth examples of some good outcomes. 

It helps if you have any experience with these type of projects. Please attach any works of experience to this application.

Other personal qualifications you need to have is: 
Good communication skills. (This means both visual and written. As I often explains in addition to draw in paint what I just wrote.)  
Being open to receive feedback. 
Being able to follow instructions. 
Be patient. (As in the start of the first projects. It takes time for us to understand each other, and work efficiently.)
Finding solutions instead of only see a problem.
Respect Deadlines.
