Working with an out of state license?

I am in another state(NC) helping to take auto auto insurancee of my mother for about 3-4 months while she recovers from a health issue. I still maintain my residence as well as auto insurance and DL in my home state(MD) and go back and forth every few weeks. While in NC I've been offered a part-time driving position(which needs to add me to their auto insurance coverage) I'd like to take the job to earn some extra $$. My question is: Would I need to change over my MD DL to NC? How would that effect my auto auto insurance in MD? Can they insure me on their NC coverage with a license from another state?Don't want to take the job if it's going to be a big hassle. I think they have State Farm commercial coverage if that helps…this is not a CDL position.
Thanks for reading!
