He can be buffed and worked magicly, use magic armor, etc, or he can sacrifice all that to nullify all magical effects in his general vecinity for a limited amount of time.
The problem with that is that his tech still works, so he can run up to his enemy, putting them in his field, and then beat the living daylights out of them.
If you want it specificly for him to be always on though, you might be better off with non-droppable SR that scales with the class level (10+1 per level), basicly that the higher level he gets, the harder it is for him to be influenced by magic of any kind.
Not only can this work, but I have used it for a nonmagical race in one of my games. He was very powerful though. With one buddy who was a Spymaster so didn't really help much except to agitate and another buddy who was a monk with incredible AC who just tanked a few guys, the character caused a 300-man squadron to flee by killing their commander (who was higher level than the PC) and 75 men without seeming to be seriously injured. And that was just with unlowerable SR...
