I would turn this around and say: Find a list of: - consumer and commercial insurance companies - healthcare insurance companies - retail banks - any industry that has been doing high thoroughput, large value, and large volume sales in a very constrained environment for more than 30 years: oil and gas, ocean and rail cargo shipping, commodity sales brokers - every major government with a digital infrastructure older than 30 years (this brings us back to pre-1990, mainframe was the only real option back then) I would posit that in each of these areas you will find very well paying jobs, very demanding and interesting work that's critical, and some extremely smart coworkers. I would go further to say that if you showed up unannounced with a security clearance, history, resume, and credible reference checks, that you could have a letter of offer (as quickly as the wheels of bureaucracy spin) and salary you could negotiate on.
