Expert level knowledge and practical experience in some of the following topics: TCP/IP routed protocols;
routing protocols such as BGP, OSPF, EIGRP, IS-IS;
forwarding techniques like MPLS (and elements of their supporting protocol suites like LDP);
failure detection and convergence protocols like BFD, STP and LFA);
encapsulation mechanisms like EVPN, EoMPLS and VPLS;
and high‑level experience working with Network Operating System like Cisco IOS XE, Cisco IOS XR, Juniper JunOS, Arista EOS and Nokia SROS.
A high level understanding of network protocols like DHCP, DNS.
Expertise in infrastructure monitoring concepts, tools and NMS systems (eg: Splunk, Greylog, Cacti, LibreNMS, Grafana, Oxidized, Weathermaps, etc.)
An analytical problem‑solving mindset, delivery focus and client‑orientation are all critical for this role
Experience in a 24/7 Mission Critical Network Environment, designing, implementing and supporting network infrastructure.
Other Roles and Responsibilities:Incident Avoidance, Incident Handling, Root Cause Analysis
Maintain and execute comprehensive procedures to efficiently respond to escalated network incidents.
Act as an escalation point throughout the duration of any network incidents, as required.
Root cause analysis investigations, pattern analysis and RFO compilation with collaboration NOC/technical/customer teams, as required.
Implement solutions to any potential problem areas.
Assist other technical teams with root cause analysis of incidents, as required.
Participate/Contribute with after‑hours/weekend rotation as required to provide Engineering‑level support for infrastructure or advanced customer‑facing issues.
Infrastructure Monitoring and Maintenance
Use real‑time and historical data to facilitate capacity planning and execute resource management, including but not limited to;
Core network capacity, fibre capacity, customer-port capacity, ARIN/IP resources, etc.
Develop & Maintain Advanced (24/7/365) monitoring systems to empower the Engineering, NOC and technical teams to react and respond to incident efficiently and effectively.
Coordinate and/or execute advanced networking tasks including migrations, upgrades, maintenance, etc. where handing off an MOP is not appropriate.
Escalation response/management for any network incidents that require escalation from NOC - fibre cuts, power issues, NPOP health, change in environmental conditions etc.
Conceptualize, Design, Test and Deploy automated networking and network system solutions in collaboration with Network Architects and other technical groups.
Training, Documentation and Reporting
Author and update Method of Procedure (MOP) documents for all key technical processes, including the deployment of new network services, device configurations, migrations, and troubleshooting practices, ensuring consistent quality and operational excellence across all projects.
Develop procedures for identifying and addressing front‑line issues that may arise from the deployment of new services or network configurations, ensuring a smooth transition for both internal and external stakeholders.
