What You'll Do

  • Key aspects of development are solved using Python code that generates parallel  time-series processing queries that execute in the OneTick engine.
  • Many tasks require the ability to develop efficient algorithms

To Be Successful in This Role You’ll Need

  • 2+ years of software engineering industrial experience (not studying in parallel)
  • 1+ years of Python (we use recent Python 3 versions)
