> That is someone who builds things in the physical world, often things that kill people if they fall over or crash. Building contractors do that too, but they're not engineers. I would say engineering is more about the design process than the actual physical making. Indeed, there usually is, eventually, intended to be a tangible result of the process, be it a bridge, ship, hairdryer, silicon wafer or container of purified chemicals. However, not all engineering has to involve making a new thing to be engineering, it can also be more efficient or effective processes that contribute to, but are not themselves, production.
