• Assist with onboarding customer firewalls and applying standardized changes through FortiManager under senior guidance.
• Review FortiGate or FortiAnalyzer logs to investigate issues and support basic security event analysis.
• Document troubleshooting steps, configuration changes, validation results, and resolutions in tickets and the knowledge base.
• Communicate clearly with clients and internal teams, and participate in an after-hours or on-call rotation with senior support available.

What You Bring

• Approximately 1–3 years of relevant networking or firewall support experience, or equivalent practical experience, including hands-on FortiGate use.
• Experience personally making FortiGate policy or rule changes and troubleshooting basic connectivity issues in FortiOS.
• Working knowledge of TCP/IP, routing, NAT, VLANs, DNS, firewall policies, and VPN fundamentals.
• A methodical troubleshooting approach, attention to detail, and the judgment to seek help or escalate when needed.
• Clear written and verbal communication, accurate technical documentation, and the ability to prioritize tickets across customer environments.

Helpful Experience

• Exposure to FortiManager, FortiAnalyzer, or centralized management of multiple FortiGate devices.
• Previous MSP/MSSP or production network support experience, including ticketing and change management.
• Relevant Fortinet training or certification, completed or in progress; familiarity with least privilege, segmentation, and logging.
