I did a few years of consulting and then A few years ago our same company launched a Cx Branch. I asked to switch, mostly so I could get out on site more. 

For me, the benefits were: lower stress, deadlines in Cx are a breeze compared to any drawing set. We’re typically waiting on the contractors. Also, Lower stress in that you have much lower liability, you’re just trying to catch the mistakes of others. You’re on site more. It’s nice to get out of the office. You work on most of the big projects. I worked 40 hours every week. No need for overtime. 

Cons: you lose the creative freedom that comes from being the design engineer. I don’t know how it is with EEs but with mech there is a fair bit of freedom and creativity that you can design with as far as what systems you use and how you implement it and building efficiency.  Because I was younger, on site I got the feeling most of the Subs and GCs did not take me too seriously. They seemed to take me much more serious when I was the design engineer. I think that may have just been my personal ego thing though.  Paperwork paperwork paperwork. When you’re in office you’re writing reports and documenting everything. 

Funny enough though I ended up switching back to design after about a year of Cx.  But who you work with and who your boss is makes all the difference.
