  • Hands-on Snowflake experience
  • Experience working with large-scale data platforms and datasets
  • Strong SQL and database knowledge
  • Experience integrating data between multiple systems
  • Financial services experience

Highly Desirable

  • Asset Management, Hedge Fund or Front Office Banking experience
