But what if "engineering" doesn't look like we would expect it to? What if its far more micro than the conception of it we have today? And if a species is extra-planetary, who is to say they must be confined to planet surface and/or conform to specific organism "vehicle?"

Quantum physics is universal, so we can expect physics-based fundamentals of surface engineering to be universal. However alien, engineered surfaces look radically different from natural. If aliens are at all common at least some aren't trying to hide like elves and hobbits.

I get the reasoning, but don't we have an extremely limited base for this? I also don't suggest aliens are "hiding," just that we suck at looking for them. A simple change of framing could alter everything we are already looking at. (i.e. earth orbits sun vs sun orbits earth)
