Our product provides financial professionals with an integrated multi-asset class trading platform to manage their order lifecycle, monitor real-time analytics, and connect with over 2500 broker destinations globally.
As our business evolves towards trends such as trade automation, portfolio trading, higher data volumes, and an increased focus on speed, we are working on multiple exciting initiatives to re-architect our entire software stack in order to meet and stay ahead of these needs and build the next generation state-of the art execution platform.
What’s in it for you:
  • Design and implement cutting-edge integration solutions for connecting Bloomberg's EMSX to AIM and third-party OMS providers, ensuring seamless data exchange and streamlined workflows.
  • Work on building a high-performance, fault-tolerant, and real-time distributed system able to process millions of transactions daily.
  • Design, develop, and release high-quality, scalable and maintainable code.

  • Work directly with product owners to build applications that clients use to tackle complex problems.
