The Infrastructure Security Specialist is responsible for the administration, implementation, technical evolution, and continuous improvement of enterprise network security infrastructure. The role provides senior technical expertise in firewalls, network security controls, secure connectivity, segmentation, VPN, and related security technologies across a geographically distributed enterprise environment. The role is expected to operate independently, provide technical guidance, and ensure network security solutions are secure, resilient, scalable, and aligned with enterprise security and technology standards

Network Segmentation & Secure Connectivity: Implement and evolve network segmentation, DMZs, secure remote access, site-to-site connectivity, cloud connectivity, and other security controls supporting enterprise and hybrid environments.
Operational Reliability & Troubleshooting: Lead investigation and resolution of complex firewall and network security incidents, connectivity issues, performance problems, and policy-related issues, including root-cause analysis and corrective actions.
Security Infrastructure Projects & Evolution: Lead or provide senior technical expertise for security infrastructure projects, technology migrations, firewall replacements, platform upgrades, cloud security integration, and infrastructure modernization.
Security Monitoring, Compliance & Resilience: Support security monitoring, vulnerability remediation, logging, configuration compliance, high availability, disaster recovery, and security control validation in collaboration with Cybersecurity and operational teams.
Technical Leadership & Continuous Improvement: Act as the network security SME, provide technical guidance to Network, Cloud, Infrastructure, Cybersecurity, and project teams, contribute to standards and roadmaps, and identify opportunities for automation and continuous improvement.

Strong knowledge of network security principles and technologies, including firewalls, NAT, VPN, IPS/IDS, network segmentation, DMZs, access control, and secure network design.
Demonstrated experience designing, implementing, and troubleshooting complex firewall and network security solutions within large or geographically distributed enterprise environments.
Experience supporting security infrastructure across data centers, corporate sites, remote locations, and cloud environments, preferably including Azure and/or AWS.
Strong understanding of security architecture, least privilege, network segmentation, high availability, logging/monitoring, vulnerability management, and security compliance principles.
Working knowledge of security automation and scripting, such as Python, PowerShell, Ansible, APIs, or equivalent technologies, with an understanding of Infrastructure-as-Code and DevOps practices.
Strong analytical, communication, and collaboration skills, with the ability to independently resolve complex technical issues and act as a senior technical SME across Network, Infrastructure, Cloud, Cybersecurity, Architecture, and project teams.
Fluency in English and French, both written and spoken.
