This is a good point. Traditionally, engineering is more synonymous with structures, engines, tools etc. Where someone takes the prepared plans and develop the final product, they are referred to as a developer/builder/tool maker. Where (usually a team) e.g. architect/structural/mechanical/civil people etc.. work on the design/prepare the plan, they are referred to as engineers. Software developers or even software programmers take the prepared plan or design spec and write code. The software architect / software engineer (ausually a team also) etc.. are responsible for preparing the plan / design spec. Now to cap it all off - there is a middle ground - called an analyst/programmer who analyse, design and develop a solution. (The creative hair dresser - could also accommodate this spot middle ground).
