Alteo is looking for a Network Administrator / Technician 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
- Maintain documentation: network diagrams, IP address management, device inventory, runbooks
- 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)
- Linux administration; scripting or automation (Bash, Python, expect)
- Spreadsheet (Excel, grist, airtable)
- Monitoring and documentation tooling: Zabbix, LibreNMS, Grafana, NetBox, DataGerry
- Datacenter or industrial site experience
