Senior Cisco SD-WAN & Network Specialist

As a Senior Cisco SD-WAN & Network Specialist within our Global WAN Services team, you will be responsible for connecting corporate entities, regional offices, and data centers across the globe—spanning from Hong Kong to Colombia.

You will join an agile, multicultural team of 8 engineers distributed internationally across Malaysia, Europe, and Mexico. Operating within a managed service framework, you will act as a high-level technical subject matter expert for both complex Build projects (integrations, office rollouts, data center setups) and Tier-3 Run operations. You will hold administrative/write access across critical fabrics to perform deep-dive troubleshooting and execute advanced configuration changes.

Key Responsibilities

1. Build & Project Execution

• Global Entity & Site Onboarding: Drive end-to-end WAN build activities for new site turn-ups, corporate acquisitions, office expansions, and data center integrations across international regions.
• Complex Interconnectivity: Collaborate closely with local LAN and Data Center engineering teams to design and implement secure network segmentation, VRF mapping, and multi-cloud interconnectivity.
• Traffic Engineering & Routing: Design and deploy robust dynamic routing topologies over diverse WAN transports to ensure optimal path selection, application delivery, and high availability.

2. Advanced Run & L3 Escalation

• Deep-Dive Troubleshooting: Serve as the senior escalation point for complex network incidents, performance bottlenecks, routing loops, or failover issues that exceed L1/L2 Managed Service Provider (MSP) capabilities.
• Direct Fabric Administration: Utilize direct write/admin access in regional fabrics to validate, test, and execute critical network changes when required.
• Capacity & Service Optimization: Oversee WAN bandwidth evolutions, policy fine-tuning, and continuous infrastructure performance enhancements.

3. Vendor Governance & Autonomous Ownership

• Autonomous Delivery: Independently manage assigned projects and client requests from initial requirement gathering through to execution, proactively mitigating risks and escalating to leadership only when blocked.
• Stakeholder & MSP Engagement: Act as a technical liaison between internal business units, cross-functional IT teams, and external Managed Service Providers.

• Experience Level:
• Senior Tier: 6+ years of experience in enterprise IT network engineering.
• Confirmed Tier: ~5 years of experience with demonstrated advanced technical expertise.

• Cisco SD-WAN (Viptela) Expertise: Mandatory hands-on experience designing, configuring, and troubleshooting Cisco Viptela fabrics (vManage, vSmart, vBond, edge devices).

  • Note: Candidates whose SD-WAN background is strictly limited to Cisco Meraki or basic cloud SD-WAN will not be considered due to the complexity of our architecture.

• Advanced Routing Protocols: Expert-level mastery of BGP and OSPF, multi-VRF segmentation, dynamic routing, and complex overlay/underlay architectures.

• Cross-Domain Knowledge: Strong understanding of LAN topologies, Data Center interconnects, and enterprise security segmentation.

• High Autonomy: Ability to operate independently in a globally distributed team without micro-management.
• Strong Communication: Professional fluency in English (spoken and written) to interact effectively with global peers, internal business partners, and third-party vendors.
• Pragmatic Problem-Solving: Sound judgment on when to resolve complex issues through peer collaboration versus escalating to management.
