The obvious play is to transition to quant dev at your current place. You'll already have a bunch of software engineers who do their best to guess what the bankers are talking about. Sell your supervision structure on the idea that you work more closely with them with an eye to transitioning. That may take some salesmanship. If you manage to cross over to quant dev you'll be able halfway to a sane working environment (it'll probably feel very relaxed to you) and at maybe half your current compensation, assuming you get somewhat lowballed while moving. Spend some time there. You're now a professional software developer. Optionally cross over into a less mental industry to move the work/life balance curve further. Hopefully you haven't burned everything you've made so far - investment banking is prone to a run of bad luck turning into unemployment, so if you're living paycheck to paycheck you've got an easy way to shed stress by not doing that any more. Good luck
