• Design and manage Juniper Secure Edge (SASE) environments integrating security and SD-WAN policies.
• Configure and monitor Juniper DDoS protection (TDD) and Dynamic Defense mechanisms.

Security Analytics & Monitoring:

• Integrate and manage Juniper Secure Analytics (JSA/QRadar) for centralized event correlation and log analysis.
• Develop and fine-tune correlation rules, alerts, and dashboards to monitor security posture and network health.
• Collaborate with SOC teams to investigate incidents and enforce network-level mitigations.

Documentation, Support & Continuous Improvement:

• Maintain detailed network diagrams, configurations, and change logs.
• Provide Level 2/3 escalation support for complex network/security issues.
• Participate in proof-of-concepts (POCs), solution testing, and deployment planning for new Juniper technologies.
• Conduct performance reviews and suggest optimization strategies leveraging AI-driven insights from Mist.

Required Skills & Qualifications:

• 5-10 years of experience in enterprise networking and security with strong exposure to Juniper platforms.
• Hands-on experience with:
  • SRX Series (firewalls, VPN, AppSecure, IPS, ATP).
  • MX Series (core and edge routing).
  • EX Series (switching, NAC).
  • Mist AI platform (wired, wireless, and WAN assurance).
  • SSR (Session Smart Router) for SD-WAN.
• Knowledge of Juniper Secure Edge (SASE), Security Director Cloud, and JSA/QRadar.
• Strong understanding of TCP/IP, BGP, OSPF, MPLS, VLANs, QoS, and high availability.
