I would say 4-5K USD without kids. Living in a nice 2 bed apartment in a good area (Dubai Marina or Downtown), driving a brand new car (1 car only) and doing some entertainment (this one can be trick, you need to think how you gonna spend your money in restaurants, bars and shows, it can be very expensive) and the more important thing in Dubai is hold on and think before expend, it’s very easy to spend everything here. Don’t expect to save a lot in your first year.
you can bid for OFF days, there are some types of biding, but as junior expect only to have a Golden day off awarded per month, after a year you may start get something more.
there is inflation in Dubai, but nowadays rentals prices are going down, I got and most of friends got around 10% discount in rental prices this year, for me means 300USD more in my pocket per month.
