You need 2 SPDT switches, which is what household 3 ways are. Positive goes to the center of first one. Then the 2 outer connectors on the switches are tied together. Then the center of the 2nd goes to the light.
What I would do, get 2 NC magnetic alarm switches. Most I see that are NC have 3 terminals so you can use it NO, too. Anyways, I would put the mag switches on the doors and when you open the door, the light comes on.
