  • Scripting capability in Python or PowerShell for automation and operational tooling.
  • Good understanding of trading lifecycle processes (trading, clearing, settlement, post-trade flows).
  • Experience supporting exchange connectivity, market data, and FIX protocols.
  • Familiarity with ITIL-based support environments, including incident, problem, and change management.
  • Confident communicator with the ability to work directly with traders, vendors, and senior stakeholders.
