The Network Engineer is tasked with designing, deploying and maintaining stable, robust and scalable network infrastructure to both customers and internal teams/partners. The Network Engineer will have subject matter expertise of network infrastructure research, design and deployment as well as expertise with various network products, network protocols, monitoring tools, and best practices.

Key Responsibilities:

Design, provision, and maintain long-haul and metro DWDM optical networks utilizing multi-degree ROADM architectures.

Execute link engineering calculations, including OSNR, chromatic dispersion, polarization mode dispersion, and optical attenuation budget.

Research, plan, design, implement and support a variety of network technologies, including but not limited to routers/routing protocols, switching, route reflection, GPON/XGSPON, KEA DHCP and DHCPv6, EVPN, upstream peering/transit management, Cloud connectivity, firewalls, SD-WAN, voice systems, IPTV/video, Wireless LAN topologies, SSL and IPSec VPN, network security practices and tools, among others.

Provide Engineering-level on-call support to NOC and guidance for any incidents, outages, degradation or troubles with infrastructure.

Perform root-cause analysis on .physical layer fiber faults, optical card failures, and transport degradation events

Preferred Skills:

Optical Infrastructure: 7+ years of hands-on experience in DWDM, CWDM, OTN (G.709), and SONET/SDH platforms in a carrier or enterprise environment.

Ciena Platforms: Hands-on operational and commissioning experience with Ciena 6500, 6200, Waveserver, RLS, and Ciena MCP (Manage, Control and Plan).

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.

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.
