What if you work on game engines, rendering engines, or simulation engines? I think 'software engineer' is different than just 'engineer', but it's used for short. Software engines, for lack of a better term, are software applications that do most of the runtime heavy lifting, of some kind, whether it's simulating worlds or rendering web pages. I agree it's different than just development, or just programming.
