Role Summary

We are seeking a seasoned Service-Provider Network Engineer with deep expertise in Juniper technologies and a track record of designing, operating, and supporting large-scale carrier-grade networks. The successful candidate will hold the top-level Juniper certification (e.g. JNCIE-SP) and bring at least 10 years of real-world experience. You will play a key leadership role: owning design and implementation of core network infrastructure, resolving complex issues, and mentoring junior engineers.

Key Responsibilities

• Design, implement, and maintain large-scale Service-Provider WAN backbones and core infrastructure using Juniper hardware & software.

• Configure routing, switching, VPN, MPLS/VPN (L3VPN, L2VPN, VPLS, etc.), QoS, multicast, and other SP-related protocols/policies.

• Troubleshoot and resolve complex network and service issues — including control-plane and data-plane problems, routing policy conflicts, MPLS/VPN issues, peering and interconnect problems, latency/performance degradations, and service outages.

• Act as escalation point for major incidents and outages; perform root-cause analysis and produce post-mortem documentation including mitigation and prevention recommendations.

• Provide technical leadership: create high- and low-level network designs (HLD/LLD), architecture documentation, run-books, standard operating procedures (SOPs), configuration templates, and network diagrams.

• Mentor, guide, and deliver technical training or guidance to less experienced engineers; review their work, share best practices, and ensure quality/capacity building in the team.

• Collaborate with cross-functional teams — operations, NOC, security, projects, vendors/partners — to deliver end-to-end network and service solutions.

• Keep abreast of emerging technologies, industry best practices, and evolving SP-network requirements; proactively recommend infrastructure or architecture improvements for scalability, reliability, performance, and security.

• Provide support for any critical incidents or security vulnerabilities that cannot wait for standard business hours.

• Provide Support during high risk or service impacting change activities that includes, failover, activation, or configuration transitions in the Network.

2. Routing, MPLS/VPN, and Core SP Protocols — Extensive knowledge of IP routing (BGP, OSPF, IS-IS), MPLS, L3VPN/L2VPN/VPLS, multicast (IGMP, PIM), QoS, traffic engineering, VPNs, network segmentation — including design and troubleshooting in large, distributed, carrier-grade networks.

3. Network design and architecture — Ability to produce both high-level and detailed network designs (HLD/LLD), including resilience, redundancy, high-availability, scalability, capacity planning, and documentation (diagrams, runbooks, network standards).

4. Network automation, scripting, and tools — Familiarity with automation and orchestration (e.g., scripting, network-management tools, monitoring and alerting frameworks) to support consistent, repeatable configurations and proactive network monitoring.

5. Security, VPNs, and network services — Experience implementing security, VPNs, firewalls, and applying best practice security policies in a provider network context; understanding of tunneling, encryption, and secure customer connectivity.

Key Behavioural / Soft Skills & Leadership Traits

• Advanced troubleshooting & problem-solving — Able to diagnose complex, multi-layer network/service issues under pressure and deliver effective resolutions.

• Visionary & strategic thinking — Ability to anticipate future network growth, evolving service demands, and design infrastructure accordingly; propose scalable, future-proof architectural changes; stay current with industry trends and emerging technologies.

• Mentorship & technical leadership — Comfortable delivering technical content, training, and guidance to less experienced engineers; reviewing and approving network designs/configurations; fostering team best practices and knowledge sharing.

• Communication & documentation — Excellent written and verbal communication; able to explain complex technical topics to both technical and non-technical stakeholders; produce clear documentation, diagrams, run books, and reports.

• Multi-project & cross-functional collaboration — Able to lead or participate in multiple concurrent projects; work collaboratively with vendors, internal teams (e.g., NOC, security, operations), and support cross-discipline integration (e.g., data, voice, cloud).

• Adaptability & continuous learning — Comfortable operating in a fast-paced, evolving environment; motivated to maintain and grow expertise; remain current with new protocols, Juniper product lines, and SP-networking trends.

Minimum Qualifications

• Bachelor’s degree in computer science, Information Technology, Network Engineering, or related field — or equivalent proven experience.

• Top-level Juniper certification for Service Provider track (e.g., JNCIE SP or equivalent expert-level Juniper credential for SP Routing & Switching).

• 10+ years’ experience in network engineering, with significant portion working in service-provider or ISP environments, designing and supporting large-scale WAN / backbone / carrier networks.

• Proven record of designing, deploying, and operating complex SP-grade networks (routing, MPLS, VPN, QoS, high-availability) at scale.
