Core Routing & Switching: Expert knowledge of enterprise/datacenter network architecture and routing protocols, specifically BGP, OSPF, and PIM.
-
Multicast Expertise: Extensive hands-on experience with multicast routing (PIM-SM/SSM, IGMP) and high-throughput multicast market data distribution networks.
Hardware Time-stamping Network Capture
-
Proven experience deploying hardware time-stamping network packet capture (PCAP) infrastructure (e.g., MetaWatch, or dedicated tap aggregators).
-
Advanced capability in PCAP analysis, microburst identification, nanosecond/microsecond network jitter detection, and end-to-end latency profiling.
Network Automation & Monitoring
-
Automation: Proficient in Python to develop network automation scripts for batch configuration deployment, state validation, and network device management.
-
Monitoring Stack: Familiarity with SNMP and monitoring/logging platforms, including Zabbix, Prometheus, and Grafana.
Financial Domain & Colocation Engineering
-
Exchange Ecosystem: Direct experience with exchange dedicated line (cross-connects/leased circuits) provisioning and exchange colocation (proximity hosting) deployments.
-
Market Protocols: Sound understanding of market data streams, financial messaging protocols (e.g., FIX, native binary protocols), and colocation rack/cabling/power logistics.
Professional Capabilities
-
Exceptional organizational and project management skills with extreme attention to technical details.
-
Clear, professional, and effective verbal and written communication skills in English.
