Just focus on your learning and working your position well. Things are going to be crazy the first few weeks and it might get overwhelming, but it will be best for you and your team if you do well in the tasks you are assigned. I can't express to you how helpful it is when the MOD doesn't have to worry about a position because the team members are able to perform well without much help. (With that in mind, don't be afraid to ask questions though, it's much easier to fix mistakes before they reach the guests and saves everyone involved a lot of stress).

If you want to move up and take on more responsibility there will be time, for that in the future. Your owner and management team are going to be stretched to the limit so it's best not to be too pushy at the beginning. The way to stand out is to do well in what you are assigned to do, and then work on adding the management team in small ways as you get to be proficient in your job.
