No research. That is, the research engineer is attempting to create things that have never existed before and that no one is certain is possible, while the design engineer is essentially trying to modify things that already exist for a slightly new task, something that everyone knows will work but will just take some effort.</p>
<p>Example: A research engineer creates some new type of laser, something that has never existed before. Design engineers then build that laser in different sizes or configurations or power levels to accommodate different applications, without expanding the actual limits defined by the research.</p>
<p>
Well, I would say that someone focused on the technical side can see four rough tiers:</p>
<p>At the top are research engineers, who get to push the limits of the state of the art.</p>
<p>Next are design engineers, who get to apply the state of the art.</p>
<p>After that are system engineers, who have some engineering work to do but also serve to interface between various design engineers.</p>
<p>At the bottom are support engineers, who don’t directly contribute to any engineering design work, but still require engineering knowledge and use it to perform select tasks and feed opinions or information back to the design teams.</p>
<p>Now, this is pretty rough because (1) this is really a continuum, not a discrete system, and because (2) depending on the company and the person your support engineers might be highly valued and important and actually contribute a LOT to the designs - there are complex and important tasks at ALL the levels, but the minimum required goes down with each step. But this works as a rough guide.</p>
<p>So if you were to take a bunch of people with aspirations (and at least nominal ability) to be R&D engineers, generally the best few would be research engineers and the worst would be support engineers.</p>
