The Network Engineer is responsible for designing, implementing, securing, and supporting MicroSourcing's enterprise network across all sites. Operating as the organisation’s primary networking specialist within a small, collaborative IT team, this role focuses on Fortinet technologies (firewalls, SD-WAN, switches and Wi-Fi), Cambium Wi-Fi, and related monitoring, automation, and security tooling. The Network Engineer will ensure maximum availability, performance, and security of the network while driving continuous improvement and modernisation.

• Network Infrastructure Management & Support
  • Deploy, configure, and maintain Fortinet FortiGate firewalls, including NGFW services, IPS, application control, web filtering, SSL / IPsec VPNs, and SD-WAN routing.
  • Administer enterprise switching (Fortinet and other vendors), managing VLANs, Layer 2/3 routing, QoS, and stack management.
  • Manage wireless networks using Fortinet FortiWLC/FortiAP and Cambium controllers/APs, ensuring reliable coverage, roaming optimisation, and WPA3/802.1X security.
  • Oversee WAN connectivity (Internet, SD-WAN, MPLS) and ISP relationships, ensuring sufficient bandwidth, redundancy, and fail-over capability.
  • Maintain accurate network diagrams and asset inventories using industry-standard tooling (e.g., NetBox or equivalent).

• Security & Compliance
  • Own firewall rule-sets, security profiles, and threat-intelligence subscriptions across all Fortinet appliances.
  • Integrate network telemetry and security logs into Microsoft Sentinel SIEM, developing analytic rules, workbooks, and incident response playbooks.
  • Implement network segmentation, Zero Trust, NAC (e.g., FortiNAC) and MFA for administrative access to networking devices.
  • Coordinate regular vulnerability assessments and patching for network hardware and firmware.

• Monitoring & Performance Management
  • Establish and maintain end-to-end monitoring using FortiManager/FortiAnalyzer and complementary NMS tools (e.g., PRTG, LibreNMS, SolarWinds).
  • Develop dashboards and automated alerts for latency, packet-loss, throughput, Wi-Fi health, and security events.
  • Produce monthly KPI and capacity reports, recommending upgrades or configuration changes where required.

• Operational Support & Troubleshooting
  • Provide Tier-3 escalation support for network-related incidents and service requests, including root-cause analysis and post-incident reviews.
  • Participate in the on-call rotation for critical network and security incidents.
  • Coordinate maintenance windows, change requests, and communication with stakeholders.

• Automation & Optimisation
  • Automate configuration deployment, backups, and compliance checks using scripting (Python, PowerShell), REST APIs, and tools such as Ansible or Terraform.
  • Champion Infrastructure as Code (IaC) approaches for network templates and SD-WAN policy deployment.
  • Drive continual service improvements, identifying opportunities to reduce complexity and cost.

• Collaboration & Documentation
  • Work closely with infrastructure, security, and application teams to ensure networking requirements align with wider IT initiatives.
  • Produce and maintain clear documentation: network standards, change records, troubleshooting guides, and knowledge base articles.
  • Provide mentoring and knowledge transfer to IT colleagues on basic network administration tasks.

Non-negotiables
