You’ll help keep critical platforms secure, reliable, and high‑performing, while contributing to modernization and automation initiatives.

What you will do:

• Provide day‑to‑day operational support for enterprise network and voice/video services, including LAN/WAN, VPNs, firewalls, SD‑WAN, MPLS, and collaboration platforms.
• Monitor network performance and availability, responding to incidents, performing troubleshooting, and taking corrective action to minimize service impact.
• Investigate and resolve complex network issues, escalating high‑risk or cross‑platform problems to senior specialists or infrastructure leads as required.
• Support network lifecycle and modernization initiatives, including platform upgrades, workload migrations, and data‑center or hybrid cloud connectivity projects.
• Maintain network security controls in alignment with enterprise cybersecurity standards, including vulnerability remediation, patching, and secure configuration practices.
• Contribute to disaster recovery and service resiliency by supporting recovery planning, testing, and validation of network services.
• Support the evolution of the enterprise security posture by implementing and maintaining Zero Trust architecture principles, including identity‑based access controls and secure edge access.
• Maintain documentation, automation, and operational procedures as well as collaborating with infrastructure and application teams to drive continuous improvement and operational excellence.

What you should have:

• Bachelor’s degree in Computer Science, Information Technology, Engineering, or a related field. An equivalent combination of education and/or experience can be considered.
• Minimum of 5 years of experience in enterprise IT infrastructure or systems administration roles.
• Practical experience supporting multiple infrastructure domains, such as networking, virtualization, storage and backup, disaster recovery, and databases.
• Experience supporting on‑premises and hybrid cloud environments, with an understanding of modern infrastructure operations.
• Working knowledge of ITSM processes (incident, problem, and change management) and operational support models.
• Strong troubleshooting, automation, and communication skills, including scripting (e.g., Ansible) and the ability to clearly explain technical issues to both technical and non‑technical stakeholders.

Technologies:

• Network Technologies – LAN/WAN, VPNs, firewalls, SD‑WAN, MPLS, and voice/video collaboration platforms.
• Cloud & Hybrid Infrastructure – Microsoft Azure and on‑premises to cloud integration.
• Automation & Monitoring – Ansible scripting and infrastructure monitoring/operational tools.
• Network Security & Zero Trust – Implementation of STNA, SASE, Identity‑aware Proxies and advanced firewall policies enforcing continuous authentication.

It would be great if you also had:

• Experience supporting enterprise infrastructure environments across one or more domains (networking, virtualization, storage, backup, or databases), with awareness of enterprise architecture and standardization practices.
• Exposure to regulated or security‑sensitive environments, including participation in audit, compliance, or security remediation activities, along with familiarity with IT service management concepts.
• Familiarity with hybrid cloud concepts and progression toward relevant industry certifications (e.g., Microsoft, VMware, Azure, networking), with ITIL Foundation considered an asset.
