  • Proven experience deploying networks in low latency
  • Proven experience in financial trading environments.
  • Solid knowledge of WAN technologies, optical networking, and fibre waves.

  • Comfortable working with monitoring tools, handling network migration and handover.
  • Experience in:
    • Multicast configuration and troubleshooting
    • Layer 1 MUX switching
    • Packet tapping and timestamping
