Answer: This is absolutely the first time I have seen this question! But, the people who answer the questions for the Q&A actually work for the National Gardening Association, not Home Depot.
If I remember correctly, we were all writing Regional Reports every other week for the NGA web site and were invited to do the Q&A when the service started many years ago.
I just checked the "jobs" section of the NGA web site and there is nothing listed there right now. Here is the url in case you want to check from time to time; it also has basic contact information for the NGA.
You might want to check through your state trade associations, Master Gardeners, local or regional garden writers, and area nurseries to see if they know of any openings as well. Best of luck with your search!
