About Calian

At Calian, we help organizations overcome obstacles, manage risks, and drive progress. Since 1982, we’ve grown from a small consulting firm into a trusted global company across defence, space, health, nuclear energy, public safety, and government.

We create innovative solutions that tackle complex challenges and help organizations and communities stay resilient, informed, and connected. If you’re driven by purpose and energized by solving real-world challenges, we want you on our team.

Job Type: Full Time

Position Overview

We are looking for a Network Infrastructure Administrator to join our Infrastructure Management team. In this role, you will be responsible for the design, implementation, and support of Calian’s network infrastructure systems, including enterprise Wi-Fi, firewall, routing, switching, policy enforcement, and automation across site, data center, and cloud environments. You will leverage your expertise in Fortinet and Zscaler technologies to ensure secure, high-performance connectivity across internet and private networks.

Working closely with Calian IT and business unit development teams, you will manage secure network connectivity, optimize firewall and SD-WAN configurations, maintain high availability and disaster recovery capabilities, and support the continuous improvement of network infrastructure. The ideal candidate is proactive, solutions-focused, and skilled at identifying and resolving complex network issues to ensure stability, security, and performance.

Responsibilities

Own and manage enterprise Wi-Fi infrastructure, ensuring optimal performance and coverage across all environments.
Administer and optimize Fortinet firewalls, VPNs, security policies, and FortiManager configurations.
Administer and support Zscaler cloud security services for secure internet and private connectivity.
Design and enforce enterprise-wide network policies, including firewall rules, access controls, and compliance standards.
Monitor and optimize network performance, capacity, and security across hybrid environments.
Implement and maintain network redundancy and disaster recovery solutions.
Integrate and support on-premises and cloud-based network services in Azure and AWS environments.
Implement network automation and monitoring tools, including FortiManager and SNMP-based solutions.
Collaborate with security teams to enforce network security best practices and compliance requirements.
Troubleshoot network issues within Fortinet environments, including firewall rules, VPNs, and wireless connectivity, quickly identifying root causes and implementing effective solutions to maintain network stability and performance.
Perform other duties as required within the scope of the role.

Qualifications

College diploma or university degree in Computer Science or a related field, or equivalent relevant experience.
3+ years of experience with enterprise networking, including routing, switching, and firewalls.
3+ years of hands-on experience with Fortinet technologies, including FortiGate, FortiManager, and FortiAnalyzer.
Experience supporting Zscaler cloud security services.
Strong understanding of network security, DNS, DHCP, VLANs, SD-WAN, VPN technologies, and the OSI model.
Experience with cloud networking in Azure and AWS environments and hybrid connectivity solutions.
Experience using FortiManager and FortiAnalyzer for centralized policy management and log analysis.
Strong analytical and troubleshooting skills with the ability to resolve complex network challenges.
