You can get it if you get in touch with a company willing to hire you on a contract basis. And once that is done you will get all paperwork needed to enter the country and then proceed to process your RP (working Visa).

There could be people trying to offer you Visa for you to come over and get a job; but just remember that asking for/trading/selling/buying VISAS is considered Illegal by Qatar authorities and the punishment is harsh to those caught red handed.

Be careful!!
