Title: Network Integration & Implementation Engineer

Grade: L2

Location: Islamabad

Company: JazzWorld

JazzWorld is Pakistan’s fastest-growing digital ecosystem, spanning connectivity, financial services, entertainment, lifestyle, enterprise and software services. As Network Integration & Implementation Engineer, you will build, integrate and migrate customer networks across firewalls, secure remote access, network access control, SD-WAN, enterprise wireless, routing and switching. Working with public-sector, financial-services and large-enterprise customers, you will deliver secure, well-documented implementations across multi-vendor environments, including live production changes and nationwide deployments.

What you’ll own

• Deploy and configure multi-vendor next-generation firewalls, including access policies, NAT, site-to-site and remote-access VPNs, IPS and threat prevention.
• Implement and upgrade network access control using Cisco ISE or equivalent, including 802.1X, MAB, TACACS+, RADIUS, device administration and MFA across mixed-vendor switching.
• Deliver branch-scale SD-WAN rollouts, including site onboarding, policy configuration, data-centre integration and cutover.
• Deploy multi-site enterprise wireless with identity-based access and guest services, and refresh routing and switching across VLAN segmentation, inter-VLAN routing, redundancy and high availability.
• Integrate AWS and Azure cloud networking and security, including hybrid connectivity where required.
• Develop implementation plans, methods of procedure, migration steps and rollback plans aligned with statements of work and approved designs.
• Execute firewall migrations, platform upgrades and technology refreshes in live production, with defined fallbacks, validation criteria and customer acceptance testing.
• Troubleshoot project and managed-services network/security incidents using firewall logs, VPN sessions and authentication events; support root-cause analysis, vulnerability assessment and audit remediation.
• Complete handovers to managed services with accurate as-built records, runbooks, monitoring details and knowledge transfer; work with OEMs, distributors and partners on technical escalations and TAC cases.
• Coach junior engineers on implementation and documentation standards, and support Solutions Engineering with effort estimates and bill-of-materials checks when required.

What success looks like

• Implementation documentation—including MOPs, rollback plans and as-builts—is complete and meets practice standards for every assigned project.
• Assigned projects reach customer acceptance without customer-impacting rollback.
• Changes are supported by documented fallbacks, pre- and post-change validation, user acceptance testing and customer sign-off.
• Managed-services handovers are complete, with no repeat escalations caused by missing documentation.
• Network and security incidents are investigated methodically, with clear support for root-cause analysis and remediation.
• The engineer becomes a recognised practice resource in at least one area: firewall, NAC or wireless integration.
• If not already held, a full CCNP Enterprise or CCNP Security certification is completed within six months of joining; Jazz will fund the exam fees.

Requirements

You may be a strong fit if you:

• Bring 5+ years of network and network-security engineering experience, including at least 3 years delivering enterprise projects in a systems integrator, service-provider or managed-services environment.

• Hold a Bachelor’s degree in Information Technology, Computer Science, Electrical or Electronics Engineering, Telecommunications or a related discipline.

• Have delivered SD-WAN rollouts across 100+ sites through customer acceptance, Cisco ISE or equivalent NAC deployments/upgrades for banks or large enterprises, multi-site identity-based wireless deployments, and live-production firewall migrations.

• Have hands-on expertise with Cisco ASA/FTD/FMC, Palo Alto NGFW/Panorama, FortiGate or Huawei firewalls, including policy, NAT, IPsec/SSL VPN, IPS and threat prevention.

• Understand Cisco ISE, 802.1X, TACACS+, RADIUS, device administration and MFA; Cisco Meraki or Palo Alto SD-WAN; and Cisco Catalyst 9800, Aruba or Huawei wireless controllers with guest access and RADIUS integration.

• Bring routing and switching experience with Cisco Catalyst, Nexus, ISR/ASR and 8000 series, Huawei or H3C switching, L2/L3 design, VLANs, routing and high availability; AWS/Azure cloud networking is an advantage.

• Are familiar with SolarWinds or equivalent monitoring tools and ServiceNow, and hold or are pursuing CCNP Enterprise/Security or relevant vendor security certifications such as PCNSA/PCNSE or Fortinet NSE; CCIE progress is an advantage.

• Have worked with Pakistani public-sector, banking or large-enterprise customers and understand change control and audit expectations; are methodical with documentation, customer-facing communication, early escalation, cross-team collaboration and nationwide travel/customer change windows, including outside office hours.
