JazzWorld, Pakistan’s fastest-growing digital ecosystem, is seeking a Senior Network Integration & Implementation Engineer to join its Network & Security practice. This role involves hands-on design, integration, and delivery of complex networks spanning data centres, enterprise WAN and SD-WAN, campus and wireless, as well as service-provider IP core and edge networks. As the Huawei technical lead, you will drive Huawei solution delivery while integrating multi-vendor environments for public-sector, financial-services, service-provider, and large-enterprise clients. You will be responsible for the networks connecting compute, storage, backup, and GPU infrastructure, collaborating closely with Systems Integration teams.

Key Responsibilities
- Develop High-Level and Low-Level Designs (HLDs/LLDs) for data centre fabrics, enterprise WAN, SD-WAN, campus, wireless, and IP core/edge networks.
- Design data centre fabrics using architectures ranging from three-tier to spine-leaf VXLAN/BGP EVPN, including multi-site orchestration for active-active and disaster recovery setups.
- Architect national-scale SD-WAN and campus solutions featuring zero-touch provisioning, overlay/underlay designs, controller high availability, and data centre integration.
- Lead Huawei implementation efforts across iMaster NCE Fabric and Campus, CloudEngine and S-series switches, NE and AR routers, and Huawei firewalls, while integrating third-party platforms.
- Manage IP core/provider-edge transformations, technology refreshes, SDN and multi-vendor migrations, and live cutovers with clear validation and fallback plans.
- Design network fabrics optimized for AI/GPU workloads and integrate with firewalls, load balancers, virtualization, cloud platforms, and existing multi-vendor estates.
- Incorporate security into network designs through firewall placement, segmentation, and policy migration; lead complex escalations and root-cause analysis.
- Prepare comprehensive documentation including test plans, methods of procedure, migration and rollback plans, and as-built records; lead customer User Acceptance Testing (UAT) and formal acceptance.
- Own Huawei technical escalations and partner engagement, maintain Huawei reference designs and configuration baselines, and mentor engineers progressing through HCIA, HCIP, and HCIE certifications.
- Support bid processes by validating solution feasibility, estimating effort and resources, assessing risks, preparing bills of quantity/materials, conducting customer workshops, proofs of concept, and technical presentations.

Required Qualifications
- 8-10+ years of network engineering experience, with at least 4 years delivering Huawei network solutions and 3 years in a technical or team lead role on large-scale programs.
- Bachelor’s degree in Telecommunication, Electrical/Electronics Engineering, Computer Science, or a related field.
- Proven track record of end-to-end production network implementation and integration for government, financial, or service-provider customers across data centre, WAN, and campus environments.
- Experience delivering software-defined networks at scale, including controller-based data centre fabrics or SD-WAN rollouts of 100+ sites through customer acceptance.
- Hands-on expertise with Huawei NE, AR, CloudEngine, and S-series platforms, and routing/switching protocols such as BGP, OSPF, IS-IS, and MPLS.
- Familiarity with VXLAN/BGP EVPN, SDN controllers, and Huawei’s iMaster NCE suite (Fabric, Fabric Insight, MDC-MDA, Campus, CloudCampus).
- Experience executing live-production technology refreshes and multi-vendor migrations with structured fallback planning.
- Strong understanding of security integration and service-provider IP core/edge networks.
- HCIE-Datacom certification is strongly preferred; alternatively, HCIP-Datacom or HCIP Routing & Switching certifications with a commitment to achieve HCIE-Datacom within three months.
