QuoteOriginally posted by: HansiIt's different between banks but a simple view (just a jab, they all do more stuff) of the way I've seen it in a few places over my limited exposure to the industry:Quant Analyst - Works with quick mockups of ideas and models intended to produce value.Quant Developer - "Productizes" the analysts work or original work done by themselves into reusable and robust code (if they are separated from IT)Front Office IT - Takes care of hardware, software installs, database maintenance, GUI coding, data cleansing, coding up if no quant devs etc.There is generally a lot of overlap between Quant devs and IT as to who does what, very often quant devs are hired under IT's payroll.QuoteOriginally posted by: JT77What type of maths does a quant dev need?What type of financial knowledge would a quant dev have which a front office IT person wouldn't?Depends on the role and the place. We have one with a MFE background, one with an actuarial background, one who used to be an doctor but found out he liked coding better etc.Most quant devs I know are devs first and quants second or not at all. Quant analysts know how to code anyway(well they should; I've interviewed a few who's analytical results I would never be able to trust).Thanks for your reply- i'll explain the reason behind my Q:I want to eventually build up a career whereby I am not only valued by my coding ability, but also my financial product knowledge. In other words, I want to be as valuable as I can. I have the ability to become a quant analyst, but I do not wish to be a researcher and spend 90% of my time developing mathematical strategies. I like the idea of being a quant dev, but I am currently trying to research if this would differentiate me from your typical front office GUI/VBA developer.
