Would it be hard to transition from that type of role back into a more product-engineering type position? Do you perceive there as being any stigma of engineering-adjacent roles?
If you're selling to engineers, it would be an easy transition. In fact, I could probably pretty easily find a job with one of my clients since they see me as an expert in the field. If you're selling to non-engineers it might be trickier. Just like with engineering, the next job you get can depend a lot on what you were doing previously. If you're coding or architecting as a sales engineer, you are set up well to do that in your next position. If you're selling a less technical product and are never really coding or architecting, then you will have to climb your way back if you want to return to SWE.
