This is a hands-on infrastructure security position focused on the operational protection of network and application environments. The successful candidate will configure and maintain security controls, monitor suspicious activity, support incident escalation, remediate vulnerabilities, and maintain strong configuration and change-management discipline.
The strongest candidates will have at least 3 years of direct experience administering Fortinet Next-Generation Firewalls, including policy creation, IPS or IDS configuration, and SSL inspection. Practical experience with WAF policies, OWASP risks, firewall-log analysis, Infoblox, Remote Access VPN, Fortinet Switches, and Nutanix will be highly relevant.
No. Monitoring is part of the responsibility, but the role also requires active ownership of firewall and WAF policies, vulnerability remediation, firmware and security updates, compliance-audit support, incident escalation, configuration documentation, network diagrams, and detailed change logs.
We do not send automatic email confirmations after every application. The review process usually takes two to three weeks, depending on the client’s priorities, role urgency, and the volume of relevant applications received.
