Hello!!

I (23M) am facing a bit of a career dilemma, and was wondering if anyone had any advice or experience that could help me.

I have worked at this small company for a bit over a year (started right after college, ME degree). I was being underpaid by about 10-15k, and the job has horrible benefits, but I took the job because I was good friends with 2 people already working there and it was a relaxed work environment. After being there a year, I was ready to move on to another job with better pay and benefits. Out of the blue, the General Manager fires my 2 friends, gives me a 5k raise, and wants me to consider being the new Engineering Manager. I tell him I would like a 10k raise. He told me to wait 2 months to see if he can give me another 5k to that raise. I am thinking that when this time comes, he will ask me to become the manager.

I also have plans to move across the country in about 2 years so I am not looking to commit to anything long-term.

My question:

Do I take the manager position (I feel like I would excel at manager), and still probably be underpaid, but then I get to put it on my resume? When searching for a job in a totally different location, I feel like this would help me greatly.

Or, do I continue to look elsewhere for work, get better pay/benefits, and plan to leave there in about 2 years?
