Software engineers in Flow Traders are working on applications that support the core business of the company. Our systems make it possible for Flow Traders to be present and competitive on exchanges worldwide. Many of these systems need front-ends that not only share the robustness and security of our trading systems, but also are intuitive, consistent across our products and beautiful to look at.

As a JavaScript Engineer you will be working together with Java core teams to design a framework used across our web infrastructure. It's expected that you have experience with different web oriented technologies and you're able to provide a solid technical vision and to be able to choose the correct stack for our specific needs. You need to know where and when things can go wrong and how to avoid these issues beforehand.

Your work won't be public for millions of users to see, but nevertheless a high standard will be demanded by the teams in our headquarters in Amsterdam, and offices in New York, Singapore, Hong Kong, London and Cluj-Napoca. Our business users are typically only a walk away, which helps to create short feedback loops and to see your changes provide value in the shortest time possible.

To enable that, we strive to follow best software engineering practices and are supported by the best working environment, latest technology and continuous support from all parts of Flow Traders organization.
