Hi I had a question about what type of positions are they hiring for?

You don't get to pick your position. You apply and they put you where they need you most. Probably pick/pack. You'll have to internally transfer to another department in 30 days if you don't like your current department. Source: work at Amazon.

You can visit hiring.amazon.com for all employment & position info. I also believe many positions are listed on Indeed, Glassdoor, etc...
