Flow Traders is looking for an experienced trading engine developer to join our growing C++ low latency equity trading engine team in Amsterdam. The ideal candidate is curious, methodical and a multi-tasker.

We value quick-witted, creative minds and challenge them to make full use of their capacities. If you aim high, the sky is the limit!

What you will do

You will be involved in requirement clarification, technical design and implementation of new trading strategies, extending and improving the application's infrastructural aspects, and writing both unit and system integration test cases as required. You'll work as part of a small team of highly motived developers keen on delivering the best quality in terms of speed and stability for our traders.

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

A day in the life

Morning normally starts with a standup meeting with your team. This is an opportunity to catch up on the progress of development, raise problems and discuss plans for the day. After standup, you go back to your desk to program, review code on pull requests submitted by colleagues, and discuss functionality with trading representatives. Whiteboards are available to let the creativity flow freely. Sometimes a production issue is raised by support, and help from development is needed to provide advice. At lunchtime, you join your team for lunch in the canteen and enjoy a company-provided lunch. During the day, if there are no pressing issues or you feel that you need a break, you can unwind at the pool table or table tennis or do a workout at the gym. After the day is done, you can join your colleagues to celebrate a successful release or socialize in our bar.
