Hmmm none of them are really what I'm after though the technomancer comes close. Odd I'd have thought there'd be one for use in Numeria especially since there's an AP based there. Oh well thanks for the replies they were helpful.
Technology in Pathfinder is linked to skills, not classes. You need the Technologist feat to use skills on tech items. Without it you can't apply skills to technology.
That said the best Technologists are going to be classes that get access to the Wizard/Sorcerer spell list. They have the best spells for supporting technology. Druids have the best anti-tech spells. Clerics deserve a special mention, especially clercis of Brigh.
Oh, and there is also the obvious Gunslinger archetype for tech. Honestly the archetypes aren't really necessary to use tech. Mainly you need your GM to provide at least one location where you can find the necessary artifacts to produce and power technological devices. Without that tech is horribly inefficient.
