  • Profile, debug, and optimize system performance in cloud-hostedenvironments
  • Develop internal monitoring tools for latency analytics (e.g., ordeRTT, market-data delays, queue states)
  • Tune garbage-collection behaviour, CPU pinning, async event loopss, and other performance parameters

  • Work closely with traders on strategy parameters, safeguards, and scenario testing

Requirements:
