  • Strong Linux and networking fundamentals (TCP/UDP, sockets, pcap/Wireshark)
  • CI/CD experience (Jenkins/GitHub Actions, Git, CMake); containerized, reproducible test environments
  • Handson design of performance/reliability tests (latency, throughput, backpressure) and flakytest triage
  • Excellent communication and documentation skills

  • FIX engine experience (QuickFIX or proprietary), exchange simulators, OMS/EMS flows, DMA/algos, drop copy
  • Observability for tests (Prometheus/Grafana/Jaeger/Tempo; log correlation)
