I'm really curious about the shape of your problem. I was an early hire at a tech unicorn and helped build many high scale systems and definitely found that our later stage hires really had a harder time dealing with the complexity tradeoff than earlier hires (though our earlier hires were limited by a demand to execute fast or lose business which added other, bad constraints.) I'm curious what your iteration of the problem looks like. We managed it by only trusting the bedrocks of our systems to engineers who demonstrated enough restraint to architect those.
