About the Job

Requirements

  • At least 5 years of hands-on network engineering or administration experience in multi-site enterprise environments.
  • Expert-level experience administering enterprise next-generation firewall platforms, including centralized management and logging/analytics tooling.
  • Strong routing and switching fundamentals, including VLANs, OSPF/BGP basics, NAT, SD-WAN, DNS/DHCP, and QoS.
  • Proven VPN experience with 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, including syslog, log forwarding, and telemetry validation.
  • A security-first approach that defaults to least privilege, questions standing access, and treats 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.

Responsibilities

  • Administer and maintain enterprise next-generation firewalls, switching, and wireless across corporate offices, including HA pairs, firmware and vulnerability lifecycle management, configuration backups, and change control.
  • Lead deployment and standardization of a unified, centrally managed network stack across 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, including scheduled rule reviews, recertification, and cleanup 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 or 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 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 access requirements and retiring legacy paths.
  • Manage ISP/carrier relationships, including 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 the ITSM platform.
  • Keep network diagrams, standards, and runbooks current in the knowledge base.
  • Deliver secure-by-design network buildouts for new and expanding corporate offices, including rack/stack, structured cabling coordination, circuit turn-up, and wireless surveys.
  • Support network integration workstreams for acquisitions and new entities.
  • Participate in change windows and an on-call rotation as needed.

Desired Qualifications

  • A relevant certification, such as Fortinet, Palo Alto, Cisco, or equivalent.
  • Scripting or automation against network platform APIs using Python or PowerShell.
  • Exposure to cloud identity and networking, such as Microsoft Entra ID, Conditional Access, and Azure networking.
  • Experience with M&A network integrations or migrations consolidating mixed-vendor estates onto a unified stack.
  • Relevant security certifications, such as Security+, SSCP, CCNP Security, or equivalent.
  • Familiarity with meeting-room and collaboration endpoint networking.
  • Spanish language skills.
