Job description

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
  • 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

Alteo recherche un Administrateur réseau pour un emploi permanent basé à Montréal.

*** Poste en télétravail depuis Montréal. Poste impliquant plusieurs sites et des déplacements à l'international (~10 à 20 %). La maîtrise de l'espagnol est obligatoire (maîtrise professionnelle totale, à l'oral comme à l'écrit), car la majorité de l'équipe est basée en Amérique du Sud. ***

Vous serez chargé(e) d’exploiter une infrastructure réseau sur plusieurs sites, y compris à l’étranger. Nous recherchons un(e) administrateur/technicien réseau pragmatique, aussi à l’aise avec le montage et le câblage des équipements qu’avec leur configuration, et capable de travailler directement avec nos équipes de site hispanophones — à distance au quotidien, et sur site lors des déploiements, mises à niveau et incidents.

Responsabilités :

  • Déployer, configurer et maintenir une infrastructure réseau multisite : commutation et routage Cisco Catalyst (VLAN, trunking, STP, LACP, routage inter-VLAN)
  • Administrer les pare-feu pfSense : ensembles de règles, NAT, VPN site à site et d’accès à distance (IPsec/OpenVPN/WireGuard), haute disponibilité
  • Mise en place et maintenance d’hôtes et de clusters Proxmox VE : provisionnement de machines virtuelles et de conteneurs, stockage, sauvegardes, réseaux virtuels
  • Dépannage de bout en bout — de la couche physique (câblage, composants optiques, matériel) aux problèmes de commutation, de routage et de pare-feu — à l’aide de captures de paquets, de diagnostics via l’interface en ligne de commande (CLI) et d’une méthodologie structurée
  • Servir de contact technique principal pour les équipes des sites hispanophones à l’étranger : guider le personnel sur site dans les diagnostics et les réparations, et rédiger des procédures et des instructions claires en espagnol
  • Se rendre sur site pour les déploiements, les migrations et les incidents escaladés
  • Tenir à jour la documentation : schémas de réseau, gestion des adresses IP, inventaire des équipements, guides d’intervention
  • Assurer la coordination avec les FAI, les fournisseurs et les sous-traitants concernant les circuits, les RMA et les installations
  • Participer aux fenêtres de maintenance planifiées et à la rotation des astreintes

Profil :

  • 3 à 5 ans d’expérience pratique en administration réseau ou en tant que technicien senior dans des environnements d’entreprise
  • La maîtrise de l’espagnol est indispensable, car vous serez amené à interagir quotidiennement avec une équipe d’Amérique latine
  • Solide expérience de Cisco IOS sur les plateformes Catalyst (compétences en commutation requises, connaissances de base en routage attendues)
  • Expérience en production dans l’administration de pfSense (ou de plateformes de pare-feu comparables)
  • Expérience dans l’exploitation de Proxmox VE (ou d’hyperviseurs comparables) en production
  • Solides compétences méthodiques en dépannage — capacité à isoler rapidement les pannes sous pression et à communiquer clairement l’état de la situation
  • Maîtrise professionnelle totale de l’espagnol, à l’oral comme à l’écrit, y compris le vocabulaire technique
  • Passeport en cours de validité et disponibilité pour voyager à l’international, parfois à court terme

Atouts :

  • Certification CCNA ou CCNP
  • OPNsense, VyOS, MikroTik ou autres plateformes réseau open source/alternatives
  • Expérience en câblage structuré et en fibre optique (raccordements, composants optiques/DAC, tests)
  • Administration Linux ; création de scripts ou automatisation (Bash, Python, expect)
  • Maîtrise des tableurs (Excel, Grist, Airtable)
  • Outils de surveillance et de documentation : Zabbix, LibreNMS, Grafana, NetBox, DataGerry
  • Expérience en centre de données ou sur site industriel
