This is a really broad skill set. "Machinery, architecture, constructs, math, physics, complex traps, and similar technologies" is likely too much to put under one umbrella. It also comes with risks.
Back in Critical Role season one Percy was a bit of an engineer. He built some semi-magical items that augmented his gunplay. It worked for the PC ... until it didn't. Taleiesin (and Orion before him) attempted to build an Archimedes Death Ray. You use a bunch if curved mirrors to harness the power of the sun to make a 'death ray' that can nearly instantly light wood on fire, incinerate a person, etc... Science and magic can both achieve amazing things. Are you prepared for the challenges of a character rolling a 40 on this skill when they're attempting to use it to build an insane death tool? Whether you allow it and have to deal with it or you deny the player the use of the skill you put into the game ... it isn't a great situation.
