IT Network Specialist
Role Overview
Job requirements
• 5+ years of hands-on network engineering/administration experience in multi-site enterprise environments
• Expert-level experience administering enterprise next-generation firewall platforms, including centralized management and logging/analytics tooling; relevant certification (e.g., Fortinet, Palo Alto, Cisco or equivalent) strongly preferred
• Strong routing and switching fundamentals: VLANs, OSPF/BGP basics, NAT, SD-WAN, DNS/DHCP, QoS
• Proven VPN experience: IPsec (IKEv2), SSL VPN and ZTNA concepts; familiarity with WireGuard-based overlay networking tools
• Experience with 802.1X/EAP-TLS, RADIUS and certificate-based authentication (PKI)
• Experience integrating network logging with SIEM and/or MDR platforms (syslog, log forwarding, telemetry validation)
• A security-first mindset: you default to least privilege, question standing access and treat rule-base hygiene as real work
• Experience operating in audited environments (ISO 27001, SOC 2 and/or SOX ITGC) with disciplined change management
• Strong documentation habits and clear written communication
• Ability to work autonomously across time zones and travel occasionally to offices and sites
• Scripting/automation against network platform APIs (Python, PowerShell)
• Exposure to cloud identity and networking (e.g., Microsoft Entra ID, Conditional Access, Azure networking)
• Experience with M&A network integrations or migrations consolidating mixed-vendor estates onto a unified stack
• Relevant security certifications (e.g., Security+, SSCP, CCNP Security or equivalent)
• Familiarity with meeting-room and collaboration endpoint networking
• Spanish language skills (we have teams and offices in Spain)
Job responsibilities
• Administer and maintain enterprise next-generation firewalls, switching and wireless across all corporate offices, including HA pairs, firmware and vulnerability lifecycle management, configuration backups and change control
• Lead the deployment and standardization of a unified, centrally managed network stack across all corporate sites, including centralized policy management, logging and analytics platforms
• Monitor network health, capacity and availability; troubleshoot and resolve incidents across LAN, WAN, wireless and remote-access layers
• Own firewall policy lifecycle management: scheduled rule reviews, recertification and clean-up to maintain least-privilege, well-documented rule bases
• Administer identity-aware network access, including 802.1X (EAP-TLS) wired and wireless authentication, RADIUS and certificate-based controls
• Manage access policies for software-defined / identity-based overlay networks, including regular ACL reviews and device access governance
• Harden network infrastructure against recognized benchmarks; track vendor security advisories and remediate vulnerabilities within defined SLAs
• Ensure network telemetry and security logs are reliably forwarded to our managed detection and response (MDR) and SIEM platforms, and validate detection coverage
• Support incident response with network-layer containment, investigation and forensics assistance
• Build and maintain site-to-site VPNs between corporate offices, data center sites, cloud environments and third parties
• Create, manage and troubleshoot secure remote access for end users (VPN/ZTNA), including onboarding new access requirements and retiring legacy paths
• Manage ISP/carrier relationships: circuit procurement, escalations and performance for office internet and WAN services
• Support internal and external audits (ISO 27001, SOC 2, SOX ITGC) with evidence, control narratives and remediation of findings
• Maintain disciplined change management for all network changes via our ITSM platform
• Document everything: network diagrams, standards and runbooks kept current in our knowledge base
• Deliver secure-by-design network buildouts for new and expanding corporate offices (rack/stack, structured cabling coordination, circuit turn-up, wireless surveys)
• Support network integration workstreams for acquisitions and new entities
• Participate in change windows and an on-call rotation as needed
Job benefits
• The expected base salary for this role starts at $120-145K annually CAD.
• Actual compensation will be determined based on factors such as experience, qualifications, and market data for the region.
• Total Compensation package may be inclusive of annual incentive bonus, and equity (long-term incentive)
• Relocation assistance (as appliable and based on successful candidate circumstances)
• Medical, dental, and vision insurance coverage – 100% company paid for employees and dependents
• Company-paid life and disability insurance
• Voluntary life and critical illness coverage available
• Employee Assistance Program and virtual health care platform
• RRSP with company match
