Finance as an industry has always been very receptive to new technologies. The sheer volume of transactions, the low tolerance for risk and the need for instant processing made computing technology and the internet a perfect force multiplier for banks.
But all of that technology has to be developed. Finance has been at the forefront of that, if not directly then by partnering with the major IT firms. If you look at the earnings reports of most IT companies, you will find that banks are some of their largest clients. Banks’ fascination with IT has reached a point where they are directly investing into a lot of these IT companies and fintech start-ups alike. Some even have in-house teams working on blockchain and other bleeding edge tech.
All of this stuff is rather interesting, but you need programming skills to get the job done. I learned C++ and a bit of Java as part of my Computer Science degree over a decade ago. But things have changed so much since then. Are you better off learning blockchain? Or perhaps diving into Python or Android app development? What are the new languages that you need for finance and fintech? For developing fintech apps, for financial modelling, for running simulations, for data science, for developing AI trading algorithms?
1. Python
Python has definitely taken the finance world by storm. Python does have an elegance about it in the way things are handled. Its learning curve is not as steep as some of the other languages. It is a high-level language which makes it more accessible to researchers and quants and that accessibility has certainly added to its appeal.
Python is especially popular for machine learning, data science and AI applications. These are certainly some of the bleeding edge applications in finance and fintech which is why Python finds such favour in our industry. It also lends itself quite well for mathematical applications like statistics thanks to its large array of libraries. No points for guessing how important that is in finance.
The immense demand for Python in the financial services industry and an acute shortage of talented Python programmers gives it the top spot in this list. Here are some Python Courses that have been chosen based on their conformity with the requirements of the financial services industry:
2. Java
Java is used extensively in the financial services industry. Some of the world’s largest banks use it for their electronic trading platforms, retail and corporate banking portals, wealth management offerings and other such front-end, customer facing applications.
Java’s popularity in the finance industry might have something to do with its enhanced security and cross platform capabilities. Security is intrinsically important in finance and the ability to offer your platform to users on a variety of platforms is also a core requirement. With Java, you have robust and easy to use security APIs, security manger that can isolate suspicious code, virtual machines etc.
Java also offers unmatched stability which is also crucial for mission-critical financial application. Not to mention its ability to run on any device due to the use of virtual environments. Choose Java if you want to create front-end applications for banks or FinTech firms.

3. Scala
Scala was born out of a need to address some of Java’s inherent issues. Since then, it has greatly increased in popularity and is widely used by software developers globally. Scala provides support for both both object-oriented and functional programming.
That functional programming aspect is a great asset for Scala. It allows for concise and compact code to be written. It inherently is a more powerful language with more elegant syntax. You can build almost anything using Scala – from front end applications to data heavy tools.
For the finance and FinTech industry specifically, the demand for Scala developers has been exploding. From data architecture to cloud based financial platforms, Scala is the preferred choice these days. It’s a language that needs to be on your radar if you want to be a finance/ FinTech developer.
Here are some excellent Scala courses to get you started:
4. C++
Learning C++ back in college was one of the most memorable experiences of my life. But I swear I am not going to let that bias influence its ranking here!
The beauty of C++ is that it is closer to the machine as compared to most of the other languages on this list. That means it is much faster which makes it ideal for High Frequency Trading systems. HFT requires such low latency that firms pay tens of thousands of dollars for the privilege of placing their servers right inside the stock exchanges!
Another advantage of C++ is that most legacy bank systems were built using C++. I would certainly be a rich man if I had a nickel for every time our IT guys used the phrase “Legacy System”.
The finance tech world is still dominated by C++ programmers but the only reason I haven’t placed it higher on this list is because there are already plenty of good C++ programmers out there. Nevertheless, it is still a solid choice especially if its speed that you need.
