We are seeking an experienced Network Engineer with strong expertise in Juniper Networks platforms — including SRX firewalls, MX routers, EX switches, and Mist-based wired, wireless, and WAN solutions. The ideal candidate will be responsible for designing, implementing, and managing enterprise-grade network and security infrastructures leveraging Juniper’s advanced technologies across routing, switching, SD-WAN, SASE, and network assurance domains.


Key Responsibilities:


1. Network Infrastructure (Routing & Switching)

  • Design, configure, and manage Juniper MX routers and EX series switches for enterprise and data center environments.
  • Implement dynamic routing protocols (BGP, OSPF, IS-IS) and ensure optimized routing performance and redundancy.
  • Perform VLAN, trunking, and Layer 2/Layer 3 switching configurations following best practices.
  • Conduct performance analysis, fault isolation, and proactive optimization of the Juniper network infrastructure.


2. SD-WAN & Mist Integration

  • Deploy, configure, and maintain Juniper Mist Edge and SSR (Session Smart Router) for SD-WAN environments.
  • Manage Mist Cloud dashboards for wired, wireless, and WAN assurance.
  • Utilize Mist AI for proactive analytics, user experience monitoring, and network optimization.
  • Implement Mist NAC (Network Access Control) policies and enforce secure onboarding of users and devices.
  • Conduct or assist in wireless site surveys and planning for optimal AP placement and coverage using Mist tools.


3. Network Security

  • Configure and manage Juniper SRX firewalls for both perimeter and internal segmentation.
  • Implement advanced security features including:
  • IPS (Intrusion Prevention System)
  • AppSecure
  • URL Filtering
  • Cloud AV/AS
  • ATP Cloud (Advanced Threat Prevention)
  • Security Intelligence feeds
  • Configure on-premise and cloud-managed SRX devices using Cloud Security Director (CSD).
  • Implement and maintain remote access VPN (IPSec/SSL) for secure remote connectivity.
  • 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.


4. 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.


5. 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.
  • Familiarity with Wi-Fi site surveys, RF planning, and Mist AP deployments.
  • Experience in network automation (Python, Ansible, or Junos Automation) is a plus.
  • Juniper certifications (JNCIA, JNCIS, JNCIP, or JNCIE) in Security, Enterprise Routing & Switching, or Mist AI highly desirable.


Preferred Certifications:

  • JNCIA / JNCIS / JNCIP (Security, Enterprise, or Mist AI)
  • Mist AI for Enterprise Certified Professional (MEA-CP)
  • Juniper Networks Certified Specialist – Security (JNCIS-SEC)
  • JNCIS-ENT / JNCIP-ENT / JNCIS-MISTAI


Soft Skills:

  • Strong analytical and troubleshooting abilities.
  • Excellent communication and documentation skills.
  • Proactive mindset for continuous learning and technology adoption.
