Shadowrun doesn't really work like that. There aren't classes in the game, just general jobs. Hackers, Street Samurai, and Magicians are the three extremes of the three worlds (Matrix, Mundane, and Astral). Between them are Adepts, Riggers, Faces, Infiltrators, and a host of other criminal positions. As general advise you'll want someone who can interact with the Matrix, someone who can Astrally Perceive, and somebody with plenty of armor and guns.
