  • Deliver robust, production-ready solutions in a fast-paced environment.

  • Exposure to C++ or willingness to work in multi-language environments is a plus.
  • Familiarity with GUI, SQL databases and Linux-based systems.
  • Interest in financial markets, real-time systems, or algorithmic trading.
