Have you considered the world of Utilities/Commodities? The world of energy is complex and many 'types' of quants come to work here; i.e. Power Systems, Economists, Programmers, Quants. Derivatives and valuation become much more complicated because markets are illiquid and the market structure is constantly changing.
Beware though, depending on the ISO you may find heavy state regulation, so that adds another complication. But what is a limit for one, may mean opportunity for another. If you're looking for pure quant/programmer, then consider opportunities in the commodities divisions of large investors.
