We're looking for an expert with deep, hands-on expertise in next-gen firewalls (Juniper, F5, Cisco), SIEM powerhouses, and centralized IAM solutions. You won't just implement defenses-you'll own the security scorecard, proactively hunt threats, and master the entire vulnerability lifecycle.

• Act as the security lead in network design reviews, ensuring that the Network assets meet stringent carrier-grade security standards.

• Execute root cause analysis and produce clear incident reports outlining timeline, impact, evidence, and remediation recommendations.

• Conduct proactive threat hunting across the identity, endpoint, and network telemetry to uncover adversary behavior and reduce dwell time.

• Create and tune threat detections using SIEM (Security Information and Event Management) to improve alert fidelity and reduce false positives.

• Drive continuous improvement of network visibility and telemetry collection to strengthen detection and response capabilities.

• Perform regular security control assessments, validating configuration effectiveness, and closing gaps discovered during incidents or hunts.

You'll need to have:

• Bachelor's degree or one or more years of relevant experience required, demonstrated through work experience and/or military experience.

• Experience in firewall functionality, Juniper (MX, ERX, etc.), Cisco, F5
