Role Summary

We are seeking a highly skilled and experienced Senior Network Architect / Engineer to lead the design, implementation, and operation of our next-generation secure Wide Area Network (WAN). This critical role requires deep, hands-on expertise in FortiGate Secure SD-WAN for distributed enterprise connectivity, coupled with an expert-level understanding of Nokia Service Router (SR) platforms and associated IP / MPLS routing technologies for our backbone or core network infrastructure. The role requires deep operational expertise in routing, traffic steering, SD-WAN overlay / underlay connectivity, and proactive fault detection in a 24x7 network operations environment .

The engineer will ensure network stability, performance, and security through structured incident handling, service management, and coordination with OEM and internal engineering teams.

• FortiGate SD-WAN Implementation : Lead the deployment, configuration, and management of FortiGate devices for SD-WAN, including Zero-Touch Provisioning (ZTP) , advanced security policies (NGFW, UTM), dynamic path selection, and application steering.
• Nokia Routing Operations : Configure, maintain, and troubleshoot mission-critical Nokia Service Routers (e.G., 7750 SR, 7210 SAS), focusing on core routing protocols ( BGP, OSPF, IS-IS ) and advanced MPLS services ( VPLS, VPRN, Segment Routing ).
• Security Integration : Ensure a cohesive security posture by integrating FortiGate's security features with the wider network infrastructure, establishing secure VPNs (IPsec / SSL), and defining network segmentation.
• Troubleshooting & Resolution (Tier 3 / 4) : Serve as the highest escalation point for complex, multi-vendor network and security incidents, diagnosing issues across both the FortiGate overlay and Nokia underlay networks.
• Documentation & Standards : Create and maintain high-quality documentation (HLD / LLD), operational runbooks, and configuration templates to ensure standardization and compliance.
• Core IP Network Operations : Administer and troubleshoot Nokia Router platforms (e.G., Service Routers) and related protocols ( BGP, OSPF, MPLS, RSVP, LDP ) essential for core Telco service delivery.
