Senior Network Engineer - Carrier / Service Provider Backbone (Juniper)

FDC Servers is hiring a Senior Network Engineer to serve as the L3 authority for its global carrier-grade backbone. The role owns complex routing escalations, network architecture and capacity planning, and mentors Tier 2 engineers while supporting Juniper-based service-provider infrastructure.

Responsibilities:

• Act as the ultimate L3 escalation point for complex routing, switching, and backbone infrastructure incidents across a global carrier-grade network
• Configure, maintain, and optimize core/aggregation/edge Juniper (QFX, PTX) routers and switches, with occasional support for Cisco platforms (IOS-XR, NX-OS)
• Architect, manage, and troubleshoot ISIS, BGP, IP/MPLS, SR-MPLS, SRv6, routing policy, and scalability at carrier scale
• Manage transit, peering, and IX relationships at the technical level: BGP policy, communities, traffic engineering, and inbound/outbound path optimization across multiple Tier 1 carriers
• Lead mitigation during severe network anomalies and DDoS events using BGP Flowspec, RTBH, and traffic scrubbing workflows
• Drive capacity planning, redundancy reviews, circuit turn-ups, backbone migrations, and major Junos software upgrades
• Validate and peer-review complex network change scripts (Juniper set-style) prior to implementation in maintenance windows
• Mentor Tier 2 network engineers, establishing troubleshooting procedures and clear escalation boundaries

Requirements:

• Prior employment with a Tier 1 / Tier 2 carrier, IP transit provider, ISP, or large-scale hosting/data center network operator
• Expert-level hands-on Juniper Junos experience in a live SP production environment (QFX/PTX class hardware)
• Deep operational command of Service Provider protocols: ISIS, BGP (full tables, peering, transit policy), IP/MPLS, SR-MPLS, SRv6, EVPN
• Practical experience with BGP Flowspec, L3VPN/L2VPN, anycast gateways, and traffic engineering on a production backbone
• Experience evaluating SP-grade hardware limitations: line-card vs. ASIC/SoC architectures, FIB scale, and platform selection
• Advanced Layer 2/3 troubleshooting: packet capture analysis, deep route table analysis, log parsing under pressure
• Strong risk-assessment mindset: you understand blast radius and customer impact before touching a production router
• Professional written and spoken English for documentation, post-mortems, and mentoring
• JNCIP-SP or JNCIE-SP certification (or demonstrably equivalent experience)
• Network automation: Ansible, NetBox API, Python, Git
• Cisco IOS-XR / NX-OS experience in SP or spine-and-leaf environments
• Experience directing remote hands teams for complex deployments, fiber rollouts, and infrastructure audits
