HI, 

IM sorry I did not understand , could you please specify which job and what is that you need specifically. In order to be a statistician , B.sc is fine, but in order to get a better job and better pay and good work nature , its better to do Post graduation too. But , Bsc stats and computer science is also sufficient enough to fetch a fair pay job. Also, Make sure to do it in a good grade college with better placements, as statisticians are required.
