Network Administrator [#4985]

Alteo is looking for a Network Administrator for a permanent job based in Montreal.

*** Remote job from Montreal. Multi-site role with international travel (~10-20%). Spanish is required (full professional fluency, spoken and written) since the majority of the team is located in south America. ***

You will be responsible for operating a network infrastructure across multiple sites, including facilities abroad. We're looking for a hands-on Network Administrator / Technician who is as comfortable racking and cabling equipment as configuring it, and who can work directly with our Spanish-speaking site teams — remotely day to day, and on-site during deployments, upgrades, and escalations.

Responsibilities:

• Deploy, configure, and maintain multi-site network infrastructure: Cisco Catalyst switching and routing (VLANs, trunking, STP, LACP, inter-VLAN routing)
• Administer pfSense firewalls: rulesets, NAT, site-to-site and remote-access VPNs (IPsec/OpenVPN/WireGuard), high availability
• Build and maintain Proxmox VE hosts and clusters: VM/container provisioning, storage, backups, virtual networking
• Troubleshoot end to end — from the physical layer (cabling, optics, hardware) through switching, routing, and firewall issues — using packet captures, CLI diagnostics, and a structured methodology
• Act as the primary technical contact for Spanish-speaking site teams abroad: guide on-site staff through diagnostics and repairs, and write clear procedures and instructions in Spanish
• Travel to sites for buildouts, migrations, and escalated incidents
• Coordinate with ISPs, vendors, and contractors on circuits, RMAs, and installations
• Participate in planned maintenance windows and an on-call rotation

Profile:

• 3–5 years of hands-on network administration or senior technician experience in enterprise environments
• Proficiency in Spanish is a must since you will interact with a latin american team on a day to day basis
• Solid Cisco IOS experience on Catalyst platforms (switching required, routing fundamentals expected)
• Production experience administering pfSense (or comparable firewall platforms)
• Experience running Proxmox VE (or comparable hypervisors) in production
• Strong, methodical troubleshooting skills — able to isolate faults quickly under pressure and communicate status clearly
• Full professional fluency in Spanish, spoken and written, including technical vocabulary
• Valid passport and ability to travel internationally, occasionally on short notice

Nice to have:

• CCNA or CCNP
• OPNsense, VyOS, MikroTik, or other open-source/alternative network platforms
• Structured cabling and fiber experience (terminations, optics/DACs, testing)
• Spreadsheet (Excel, grist, airtable)
• Monitoring and documentation tooling: Zabbix, LibreNMS, Grafana, NetBox, DataGerry
• Datacenter or industrial site experience
