ITT: Post your dream job. If it's not well known, describe it.

Mine: Algorithmic Trading Quant.
From Wikipedia:
Algorithmic trading quantitative analyst

"Often the highest paid form of Quant, ATQs make use of methods taken from signal processing, game theory, gambling Kelly criterion, market micro structure, econometrics, and time series analysis. Algorithmic trading includes statistical arbitrage, but includes techniques largely based upon speed of response, to the extent that some ATQs modify hardware and Linux kernels to achieve ultra low latency."
And don't forget that 300k starting :)
