A quant (quantitative analyst) is a financial industry professional whose qualifications also include advanced mathematics and and computer skills.
Typically, quants design complex mathematical models for use in securities trading. Although the term is most commonly associated with finances, economics and risk management, it is increasingly used in a wide variety of other industries. Essentially, any area that requires quantitative analysis might employ a quant. With the advent of big data and the complexities of big data analysis, most industries and organizations could benefit from an employee with that skill set.
In a growing trend, IT professions have skill sets that have traditionally been thought of as part of separate career paths. Other examples of IT jobs with converged skill sets include growth hackers, chief marketing technologists (CMT), DevOps and WebOps.
