Get a lawyer -- preferably one who is familiar with FAA/DHS security requirements -- and get his opinion as to whether this counts as a "conviction" or not in the jurisidiction where you were arrested. If it is not a conviction, just an arrest and dismissal, then you should have very little to worry about. Most companies will not use an arrest record against you (it raises all sorts of problems under state and federal law). On the other hand, if it is a "conviction," you might have a problem under the FAA/DHS criminal background screening requirements.
