JazzWorld, Pakistan’s fastest-growing digital ecosystem, is seeking a Senior Network Integration & Implementation Engineer based in Karachi. This senior hands-on role serves as the Huawei technical lead within the Network & Security practice, responsible for designing, integrating, and delivering complex networks across data centres, enterprise WAN and SD-WAN, campus and wireless, as well as service-provider IP core and edge environments. The engineer will lead Huawei technical delivery while managing multi-vendor integrations for public-sector, financial-services, service-provider, and large-enterprise clients. This role owns the networks connecting compute, storage, backup, and GPU infrastructure, collaborating closely with Systems Integration teams.
Key Responsibilities
- Produce High-Level and Low-Level Designs (HLDs/LLDs) for data centre, enterprise WAN, SD-WAN, campus, wireless, and IP core/edge networks.
- Design data centre fabrics ranging from traditional three-tier architectures to spine-leaf VXLAN/BGP EVPN, including multi-site orchestration for active-active and disaster-recovery setups.
- Develop national-scale SD-WAN and campus solutions featuring zero-touch provisioning, overlay/underlay architectures, controller high availability, and seamless data centre integration.
- Lead Huawei implementation efforts across platforms such as iMaster NCE Fabric and Campus, CloudEngine and S-series switching, NE and AR routing, and Huawei firewalls, while integrating other vendor technologies.
- Deliver IP core/provider-edge transformations, technology refreshes, SDN and multi-vendor migrations, and live-production cutovers with comprehensive validation and fallback plans.
- Design network fabrics optimized for AI/GPU workloads and integrate networks with firewalls, load balancers, virtualization, cloud platforms, and existing multi-vendor estates.
- Embed security into network designs through firewall placement, segmentation, and policy migration; lead complex network escalations and root-cause analysis.
- Prepare detailed documentation including test plans, methods of procedure, migration and rollback plans, and as-built records; lead customer User Acceptance Testing (UAT) and formal acceptance processes.
- Manage 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 alongside Solutions Engineering by validating feasibility, estimating effort and resources, assessing risks, preparing bills of quantity/materials, conducting customer workshops, proofs of concept, and delivering technical presentations.
Required Qualifications
- Minimum of 6 years’ experience in network engineering, including 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 or Electronics Engineering, Computer Science, or a related field.
- Proven track record of end-to-end production network implementation and integration across data centre, WAN, and campus environments for government, financial-services, or service-provider clients.
- Experience delivering software-defined networks at scale, such as controller-based data centre fabrics or SD-WAN rollouts exceeding 100 sites through customer acceptance.
- Hands-on expertise with Huawei NE, AR, CloudEngine, and S-series platforms, and routing/switching protocols including BGP, OSPF, IS-IS, and MPLS.
- Familiarity with VXLAN/BGP EVPN, SDN controllers, iMaster NCE-Fabric/Fabric Insight/MDC-MDA, iMaster NCE-Campus or CloudCampus platforms.
- Experience executing live-production technology refreshes and multi-vendor migrations with structured fallback planning, including security integration and service-provider IP core/edge networks.
- HCIE-Datacom certification is strongly preferred; alternatively, HCIP-Datacom or HCIP Routing & Switching certifications are required, with a commitment to attain HCIE-Datacom within three months if not already certified.
