Network Administrator

Hi there! Thanks for stopping by 👋

Are you actively looking for a new opportunity? Or just checking the market? Well… you might just be in the right place!

We’re looking for a Network Administrator to join our Network Operations team in Montreal, Quebec. As a Network Administrator, you will help ensure the availability, performance, and security of Lightspeed’s internal corporate network across our global offices. This role supports Lightspeed’s employee and office connectivity—not the networks operated by our merchant customers. You will manage and improve our LAN/WAN connectivity, Fortinet infrastructure, enterprise Wi-Fi, site-to-site VPNs, ISP services, and physical network environments.

This is an AI-first network operations role. You will work closely with our EMEA network counterpart to apply agentic AI and automation to network operations moving the team toward earlier detection, faster investigation, and prevention of service issues, while reducing repetitive manual work.

Please note that we are only accepting candidates located in Montreal.

What you’ll be doing:

Network Operations & Reliability

Administer, configure, and troubleshoot global Fortinet network environments, including FortiGate firewalls, FortiSwitch, FortiAP, FortiManager, and FortiAnalyzer.

Maintain and optimize enterprise LAN/WAN infrastructure, routing, switching, firewalls, SD-WAN, wireless networks, VPNs, VLANs, DHCP/DNS, and ISP connectivity across global offices.

Serve as a Tier 2/3 escalation point for complex network issues, leading incident triage, root-cause analysis, and implementation of long-term corrective actions.

Support network reliability initiatives, including redundant connectivity, dual-ISP failover, VPN resiliency, and centralized network management.

Execute network changes and upgrades following established change management procedures, including testing, maintenance windows, validation, and rollback planning.

AI-Driven Automation & Proactive Operations

Partner with global network teams to identify and implement AI-driven and automation solutions that improve network operations, reliability, and efficiency.

Develop and deploy AI-enabled workflows, scripts, and API integrations for network monitoring, configuration management, log analysis, incident investigation, and troubleshooting.

Leverage network telemetry, monitoring platforms (including PRTG), and Fortinet management tools to improve anomaly detection, intelligent alerting, and proactive issue resolution.

Evaluate automation initiatives and measure improvements in incident detection, resolution times, network reliability, and operational efficiency.

Wireless Infrastructure & Global Site Delivery

Design, deploy, and optimize enterprise Wi-Fi 6/6E infrastructure across global office locations, including RF surveys, heat mapping, capacity planning, and performance tuning.

Troubleshoot and optimize wireless connectivity, roaming, and certificate-based (802.1X) authentication to ensure reliable, high-performance network access.

Lead network infrastructure delivery across North America and APAC for office moves, expansions, and refresh projects, including hardware procurement, cabling, rack specifications, ISP coordination, and equipment commissioning.

Coordinate with Facilities teams, contractors, and service providers on network installations, circuit deliveries, infrastructure upgrades, and site cutovers.

Support physical infrastructure deployments, including network hardware, rack and cable management, UPS systems, and out-of-band management.

Documentation & Operational Excellence

Maintain accurate network documentation, including network diagrams, IP addressing schemes, port mappings, ISP inventories, and operational runbooks.

Develop standardized deployment templates, automation playbooks, and procedures to streamline network installations, firmware upgrades, and ongoing maintenance.

Collaborate with global IT and cross-functional teams to share technical knowledge, improve operational processes, and support Service Desk troubleshooting capabilities.

What you need to bring:

5+ years of hands-on experience administering enterprise office networks across a multi-site global environment.

Demonstrated proficiency managing Fortinet infrastructure (FortiGate, FortiSwitch, FortiAP, FortiManager).

Strong enterprise Wi-Fi experience, including RF planning or surveys and certificate-based wireless authentication.

Strong understanding of TCP/IP, VLANs, BGP/OSPF routing, DNS/DHCP, IPsec VPNs, STP/BPDU protection, and QoS.

An AI-first approach to problem-solving: curiosity about applying AI and automation to network work, sound judgment in validating outputs, and an understanding that AI recommendations must be checked before operational use.

Enterprise experience in network authentication using PKI and digital certificates, including 802.1X/EAP-TLS, RADIUS, root and intermediate Certificate Authorities, certificate lifecycle management, and integration with identity services.

Experience with SD-WAN, hub-and-spoke network design, redundant tunnels, dual-ISP failover, or out-of-band management.

Experience working directly with carriers, hardware resellers, and third-party managed service providers (MSPs).

Proven ability to troubleshoot complex issues logically, perform RCA, and document clear technical playbooks.

Proven hands-on experience deploying and administering Fortinet network solutions (FortiGate, FortiSwitch, FortiAP, FortiManager), alongside a solid understanding of broader multi-vendor networking technologies.

Hands-on experience working alongside Project Managers and cross-functional partners to drive network implementations, office expansions, and infrastructure upgrades from design to cutover.

Nice to have:

Experience delivering an AI or agentic-AI project end to end. Be prepared to describe the problem, your role, how you designed and validated the solution, how it was rolled out, and the positive impact on the business or team.

Experience building AI-assisted workflows or integrating AI tools with network telemetry, logs, configuration data, or operational systems.

Experience delivering network automation projects using Python, Ansible, Terraform, APIs, Git, or configuration templates.

Experience with enterprise Wi-Fi platforms with Fortinet Technologies.

Fortinet certification (FCP or relevant FCSS specialization), CWNA, or practical training in Fortinet SD-WAN, FortiSASE, FortiAnalyzer, FortiMonitor, or network automation.
