Trading Tools Software Engineer

Flow Traders is looking for experienced Software Engineers to join our growing Development team in Amsterdam. This is a unique opportunity to work at a leading proprietary trading firm where entrepreneurship, innovation, and technology are at the heart of everything we do. We value sharp, creative thinkers and give them the freedom and responsibility to make a real impact.

As a Software Engineer at Flow Traders, you will build the systems that power our global trading business and help us compete on exchanges around the world.

Since markets never stand still, we work in small, business-aligned teams and use agile practices to respond quickly to change.

You will work closely with Trading every day, creating fast feedback loops and a clear view of the value your work delivers. To support collaboration and encourage autonomy, we build and maintain shared libraries, promote code reuse, and continuously refine our approach to application architecture.
