# A Simple Guide to Become a Quantitative Developer

A quant developer is yet another interesting role in the quantitative trading domain. There is a whole lot of difference between an algorithmic trader and a quantitative developer. While an algorithmic trader is the one who executes the trading strategies after analysing the market, a quant developer is the one behind all the programming of the algorithms. Let us find out more about the quantitative developer as this article covers:

## Who is a Quant Developer?

A quant developer is a programmer who finally develops the strategies with the help of a programming language. S/he is responsible for providing financial solutions to the quantitative trading industry. Quantitative developers, thus, need to have a thorough knowledge of applied mathematics, statistical models, algorithms and scientific computing.

Quantitative developers usually work at an investment bank, a hedge fund, a brokerage firm or a financial securities firm.

Going forward, let us find out the types of quant developers.

## Types of Quant Developers

Mainly, there are two types of quant developers in the financial domain:

• Front office developers
• Middle office developers
• Back office developers

Front office developers

Quant developers who work with quantitative analysts and help to implement as well as optimise the financial models. This implies getting the prototype code from a programming language such as Python and then rewriting it in another programming language such as C++ or Java. Front office quantitative developers directly interface with the clients to deliver tailor-made software and analytical tools.

Middle office developers

These are the quantitative developers who perform a middle office role at the banks. At the investment banks, this implies working on large-scale systems. They are involved in coding of the trading infrastructure which helps the quantitative analysts or traders in running or executing their models on.

Back office developers

These developers are the ones who perform the role at the back office for tasks such as model validation and risk management. For this role, you need to have the theoretical knowledge/skills, analytical capabilities and a deep approach to a problem. Model validation helps with solving the problems at the back end so as to avoid any technical problems further.

Next, we will find out what qualification helps to become a quant developer.

## Educational Qualification to Become a Quant Developer

As we discussed in the definition of a quantitative developer, it is the mix of finance, computer science, applied mathematics, statistical models, algorithms and scientific computing which a quant developer requires to be knowledgeable in.

An aspiring quant developer must learn a coding language, especially out of the most common ones, such as Python, C++, C#, R and Java.

Also, the knowledge of tools is required to become a quant developer since these tools help with backtesting and finalising the strategy for trading. Some of the general tools/platforms are discussed below in the article.

Moreover, Quantitative Finance is another subject which provides the knowledge required to analyze financial markets and securities. This analysis is basically done by using mathematical models and huge datasets, hence, the specialists in this field are known as quantitative analysts.

Nevertheless, a quantitative developer gets much better at the job if he/she possesses the knowledge regarding the financial markets and pricing securities so as to understand what to code for the analyst.

For instance, if the quantitative analyst comes up with a bull-market or bear-market strategy, the quant developer must have the knowledge of the intricacies of markets as well as the prediction/pricing practice of the securities.

Hence, quant developers need not have their own strategies. They simply need to understand and adopt strategies to perfectly automate them.

Moreover, it is equally essential to possess the knowledge of risk analytics for the management of risks which most of the financial models are subjected to.

Hence, it is really crucial to acquire the knowledge of using quant models that help the analysts to analyse past data, current as well as anticipated data for the future.

Let us now find out the job description for a quantitative developer.
