About The Position

At gFiber, we believe that great internet has the power to drive innovation, strengthen communities, enable the impossible, and do all the everyday things that make all of our world go round. And the job of creating better internet is never done - so we’re growing! Our team is committed to building a place where people who want to make a difference can grow their careers and find their spot to belong. This role is not eligible for immigration sponsorship. We are seeking a highly skilled and experienced Commissioning Network Engineer to lead the turn-up, integration, and operational handoff of enterprise and service-provider-grade network infrastructure. As an L3 Commissioning Specialist, you will be the final technical authority responsible for validating complex network deployments, conducting high-level acceptance testing, and resolving critical, high-tier configuration and routing issues before systems go live in production. This role requires deep expertise in multi-vendor routing and switching, network automation, structural fiber/optical interconnects, and strict adherence to post-configuration quality assurance frameworks. You will work closely with deployment teams, network architects, and field engineers to ensure seamless, zero-downtime integration of new sites, data centers, and core network nodes.

Requirements

Bachelor's degree in Computer Science, a related technical field, or equivalent practical experience.
5 years of hands-on experience in network engineering, deployment, or L3 support within an ISP, data center, or large enterprise environment.
Experience with BGP (iBGP/eBGP), OSPF, IS-IS and MPLS (L2VPN, L3VPN, VRFs).
Experience working with VXLAN, EVPN, STP/RSTP, LACP, VPC, and VLAN tagging strategies.
Direct experience configuring and commissioning enterprise/ISP hardware, including Juniper (Junos), Nokia (SR-OS/OLT), Siklu and Ruckus Switches.
Proficiency with network testing tools (e.g., IXIA, Spirent, EXFO) and scripting languages (Ansible, YAML,).
Knowledge of optical power meters, OTDR testing, fiber types (SMF/MMF), transceiver diagnostics (SFP+/QSFP28), and serial console pinout mapping.

Nice To Haves

Exceptional root-cause analysis skills under high-pressure deployment or maintenance windows.
Ability to translate complex engineering status updates to non-technical stakeholders and write clear, standard operating procedures (SOPs).
Flexibility to work late-night maintenance windows (typically 12:00 AM – 6:00 AM) and occasional travel to regional pop sites, data centers, or central offices as needed.

Responsibilities

Lead the end-to-end commissioning, provisioning, and integration of core routers, switches, firewalls, optical transport gear, and edge devices across data center, campus, and ISP environments.
Execute rigorous pre-flight and post-flight testing (failover testing, and optical light-level verification) to ensure hardware and topology match baseline architectural designs.
Serve as the final escalation point (L3) during deployment windows to diagnose and resolve complex Layer 2/3 routing, switching, and security protocol issues.
Provide technical guidance and training to L1/L2 field technicians and contractors regarding physical fiber standards, console pinouts, and turn-up procedures.
