As far as many traders here, I'm assuming, this isn't really a 'field' to switch into such as a typical career change, its more something to learn about and then try to apply what you learn (perhaps on paper with paper trades etc.), and if you find you have a knack for it, you might quit your job and trade fulltime. Many have taken the professional industry route and become traders, but that's far from necessary imo.
The fact that you can understand complex systems in your job can be an asset, but that also doesn't mean if prices are tanking you will have the balls to buy, or if you will be crying uncle and are too afraid to lose more money, and thus become a seller with everyone else (or that you will be disciplined to use stop loss orders, or be disciplined to stick a particular 'system' or approach that you've chosen etc.)
Find out if you have a knack for it first, and maybe if you have a natural intuitiveness in what you read about the markets and what you observe, then continue to take the next step, whichever that is at the time.
It sounds like there's no need to put any monetary investment in it where you are at this point since there is so much you can do before quitting a job and trading immediately.
