I might be able to provide some insight. I am based out of NYC and obtained the SE license a few years ago. The benefit of this additional license in the NYC market mostly resulted in recognition and celebration of the accomplishment among my engineering peers. Additionally, it increased the frequency of my interactions with co-workers that sought input on conceptual structural approaches and code interpretation due to the newly added “clout.” Therefore, I was viewed as one of the technical leaders, informally, by my colleagues endorsed by the obtaining the SE. However, there were no financial incentives or promotions associated with obtaining the SE license, at least in most NYC firms. Also worth mentioning, most NYC developers and architects that bothered to inquire about the SE designation displayed in my e-mail signature didn’t comprehend its significance, misguided by the belief that all licensed Civil PE professionals employed in structural design firms are equal to a licensed SE. Luckily for me, I was in the process of transitioning to a boutique NYC structural firm seeking to expand it’s engineering services to other states that recognize or require the SE license (e.g. IL, CA, etc.). So this led to a significant boost in compensation (50% + profit sharing) since my duties and responsibilities increased beyond the conventional technical/managerial roles normally available to most experienced professionals. Having worked for two of the most prominent international structural engineering firms in NYC, I would say that promotions/compensation were by and large influenced by:
• Deliverables Production (aka high multipliers)
• Business Generated
• Cumulative Years of Experience
Technical ability is generally not a trait that will increase promotion potential or compensation beyond a few roles at the very start of a structural engineering career. From my personal experience, the most technical individuals do not ascend beyond low supervisory (i.e. Senior Project Engineer, Project Manager/Associate) positions, unfortunately. However, if you do manage to become a recognized subject matter expert that will trump all my previous commentary regarding the limitations for technically inclined persons.
All this to say that in NYC the SE license is indeed superfluous since it will merely server to validate technical ability. Obviously there’s a lot more nuisances than mentioned above when talking about career development and compensation. Just my $0.02.
Personally, I pursued the SE due to my passion for structural engineering and not because of what it could do for me in the job marketplace - not that I’m complaining about it’s benefit in that regard!
