The mission consists of technical support for the design, implementation, operation, and continuous improvement of a highly available, secure, and low-latency network.

Missions

The development and documentation of detailed designs for data center, campus, and market infrastructure networks (OSPF, BGP, VxLAN-EVPN, DWDM, multicast, NAT, low latency).

The configuration, provisioning, and execution of failover, migration, and upgrade activities with minimal service impact.

The 24/7 operation of the network, using Zabbix, Grafana, SNMP, and Syslog for network health monitoring and alerts. Conducting root cause analyses of incidents and driving remediation as well as post-incident reviews.

The definition and monitoring of key performance indicators (KPIs) and service level agreements (SLAs) (latency, availability, jitter, packet loss). Proposing improvements to topology, routing policies, and monitoring tools.

Close collaboration with security, infrastructure, application, and trading teams. Updating network architecture diagrams.

Participation in an on-call rotation and response to network incidents in accordance with CIB incident management processes.
