Top 6 Skills Every Fintech Engineer Must Have

If you’re entering the fintech world of engineering, it’s vital that you carry more than a Bachelors degree and a “can do” attitude. Today, being highly skilled in your field is no longer enough. The modern workforce is highly competitive, highly educated and more complex. The engineers that make the biggest impact are those who bring something extra to the table - or lots of extra “somethings.”

Today’s fintech engineers need to have the skills to navigate problems their predecessors never had to deal with - problems like full cloud integration, rapidly changing technology, remote workforces, an “instant gratification” society that demands 100 percent functionality - no exceptions, and the type of skillset that merits new workplace norms.

As an HR professional, I have reviewed hundreds of resumes, and I know what it takes for an engineer to rise to the top of the fintech stack. Here are the top 6 skills you need to master to have a thriving engineering career in the fintech industry.


For engineers, building applications used to be a matter of creating one cohesive system with many built-in components. On one hand, this made it easy for engineers to work with all of their data points under one roof. On the other hand, it made it difficult to make small changes to scale an application. Today, most engineers work with Microservices, stand-alone services with individual goals that all work together to build larger applications. As a successful Fintech engineer, you need to be comfortable with this multi-faceted approach. To get started, get familiar with Spring Boot, Jersey, Swagger, and Dropwizard.


Let’s face it. Life is lived in the cloud. It’s important that you know how to work with data across various remote networks, rather than data stored in one location. It’s possible that some clients will prefer in-house applications, but if you walk into a new employer without the ability to be cloud-based your tenure will be short-lived. 

Continuous Integration & Deployment (CICD)

It’s important that you know how to write code that can get to your users quickly and never lose functionality when changes are made. Some best practices to make CICD a reality are to commit all of your code to a single depository, to run a functionality test every time you change existing code, and to automate deployment.

High Availability & Security

We live in a fast-paced world. There is no excuse or tolerance for systems and applications with any downtime or failure. In fintech when billions of dollars are being processed, it can be devastating to a business and customer with a network goes down. All of your systems must maintain 100 percent operational if you want to be known for trusted and failure proof technology, which means you need to know how to build and work with high availability systems.

Open Source Technologies

Open source simply means that code is available to the public and can be modified to fit each users’ needs. It’s vital that you’re comfortable with the most common open source technologies (Linux, Android, WordPress, etc.) and that you know how to modify the code based on yours or your client’s needs.

Soft skills

For better or worse, the workforce is moving toward a gig economy. Whether you choose to work freelance or in a firm, odds are high that you will need to collaborate with remote workers. The ability to communicate remotely, work with a wide variety of people, and manage cross-country working relationships will make you more employable (and promotable). 

If you want to succeed as a fintech engineer, it’s imperative that you take the initiative to constantly build out your skill set. This means taking classes, seeking out insight online, and working with a company that will help develop your skills. The competition is high, but your career possibilities are unlimited, as long as you keep learning.
