I am graduating with Ph.D. in Computer Engineering, in Singapore, want a quant job.

Somewhat ironically, even though my degree is in computer engineering, I am more interested in the economics and core mathematics side of the job rather than the coding side. (But I have decent coding skill in C++, Matlab and basic Python etc.) In particular, I take a lot more interest in things like stochastic integral, Markov process, filtration, Martingales etc. than in writing codes. How far is it possible isolate one from another (i.e. the mathematics side from the coding side)? Are there roles which are heavier on mathematical concepts and lighter on coding? Is there any specific type quant job/keyword etc. I should look for?
