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

Integral 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.

1. 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.

1. 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.

Requisitos mínimos

Experience Level:

Senior Tier: 6+ years of experience in enterprise IT network engineering.

Confirmed Tier: ~5 years of experience with demonstrated advanced technical expertise.

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.
