ph3Role overview /h3 pWe are seeking a Senior Network Engineer (L3) to design, implement, and operate resilient, high-performance, and cost-efficient network infrastructure that supports both internal platforms and customer-facing services. /p pOperating at Layer 3 escalation and engineering depth, this role is part of a collaborative engineering team responsible for delivering robust, scalable, and secure network solutions. The successful candidate will contribute to and influence network designs through governance forums (TDA / peer review), produce and implement High-Level and Low-Level Design (HLD/LLD) documentation, and adhere to structured Service Design and Service Transition principles. /p pThe role includes the delivery of modern spine-leaf and perimeter network architectures, with a strong focus on operational readiness, scalability, and long-term maintainability. /p pThis is a hands‑on senior engineering position focused on technical depth, implementation, and operational excellence. It is not an architecture‑only role, nor is it a ticket‑based NOC position. /p h3What you'll do /h3 ul liContribute to peer‑reviewed network designs and implement approved HLD/LLD artefacts to ensure scalable, resilient, and standards‑aligned infrastructure is delivered correctly the first time. /li liDeploy and validate spine‑leaf and enterprise routing architectures to support high‑performance data centre and customer environments without introducing instability or technical debt. /li liAdhere to governance frameworks (TDA, peer reviews, change control) to prevent uncontrolled configuration drift and ensure long‑term maintainability. /li liEngineer and optimise complex routing environments (BGP, OSPF, EIGRP, MPLS, advanced L2/L3 protocols) to guarantee deterministic failover, predictable convergence, and sustained network stability at scale.



/li liDiagnose and resolve deep routing and switching issues at Layer 3 to minimise downtime, eliminate recurring faults, and protect service availability. /li liEngineer and administer enterprise firewall platforms (Palo Alto, Fortinet, Cisco) to enforce structured, secure, and auditable perimeter controls that protect customer and internal services. /li liDesign and maintain clean, segmented network zones and rule bases to reduce attack surface, prevent rule sprawl, and support evolving security strategy. /li liLead technical investigations during high‑severity outages to protect platform resilience and restore service with confidence and precision. /li liProduce and maintain accurate HLD/LLD documentation, topology diagrams, and configuration standards to eliminate tribal knowledge and enable operational readiness from Day 1. /li liEnsure all network changes transition through Service Design, Service Transition and Change Management principles to avoid undocumented risk and operational fragility. /li liIdentify and implement automation opportunities to reduce manual configuration risk, improve deployment consistency, and increase engineering efficiency at scale. /li liContinuously review network performance, resilience, and cost posture to improve reliability while optimising infrastructure spend. /li /ul h3What are we looking for /h3 h3Technical Skills /h3 ul li7+ years hands‑on network engineering experience in enterprise, service provider,



or data centre environments. /li liDemonstrated ownership of production routing and switching environments, not limited to support or monitoring roles. /li liProven experience implementing and supporting BGP, OSPF, MPLS, and advanced Layer 2/3 architectures in live environments. /li liHands‑on experience administering and engineering enterprise firewall platforms (Palo Alto, Fortinet, Cisco ASA or equivalent). /li liExperience operating as a Tier 3 escalation point, leading deep technical diagnostics and contributing to root cause analysis. /li liExperience working within structured engineering frameworks involving HLD, LLD, peer review, and controlled service transition. /li liStrong documentation, runbook and process design skills. /li liExposure to automation or configuration standardisation practices in network environments. /li /ul h3Experience education /h3 h3Strongly preferred /h3 ul liCisco CCNP Enterprise (or equivalent advanced routing certification) /li liPCNSE (Palo Alto Networks Certified Network Security Engineer) or equivalent Fortinet certification (e.g., NSE4/NSE7) /li /ul h3Highly regarded /h3 ul liCisco CCIE (any track) /li liRelevant MPLS or Service Provider certifications /li /ul h3Soft Skills /h3 ul liVery good problem‑solving skills, open mind towards feedback, and can‑do attitude. /li liSelf‑motivated and self‑managing, with excellent organisational skills. /li liClear communication, documentation, and cross‑team collaboration skills. /li /ul h3What's in it for you /h3 ul liPrivate life and health insurance for you and your family. /li liFour weeks per year to work from anywhere for eligible employees. /li liLearning Pocket for personal development. /li liA hybrid working model with versátil hours. /li /ul /p #J-18808-Ljbffr
