Senior Network Design Engineer

About Role

We are seeking a highly skilled Network Design Engineer with strong expertise in enterprise networking, SD-WAN migrations, security transitions, automation, and an AI-First mindset.

Our client is migrating their core infrastructure to the Cisco SD-WAN (Viptela) architecture. The ideal candidate is a proactive, self-sufficient professional who can independently gather requirements, design end-to-end migration strategies, engage stakeholders both remotely and on-site, and execute migrations within defined maintenance windows.

This role requires a structured, migration-driven approach and the ability to manage multiple parallel projects across distributed European locations.

Key Responsibilities

• Design, implement, and manage Collapsed Core architectures
• Configure and troubleshoot advanced Layer 2 / Layer 3 technologies (VLANs, EtherChannel, MPLS, OSPF, BGP at the Edge)
• Lead migrations from legacy infrastructures to Cisco SD-WAN (Viptela)
• Design and support firewall transitions from Fortinet environments to SD-WAN tunnels integrated with Zscaler
• Manage enterprise wireless environments (Cisco WLC)
• Drive end-to-end migration projects (audit → assessment → design → implementation → cutover → post-migration validation)
• Coordinate multiple remote site migrations (20–300 users per location)
• Travel within Europe for site audits and critical migration phases when required
• Automate network deployments and changes using Ansible, Terraform, and Python scripting
• Leverage AI and LLM tools (e.g., ChatGPT, Claude) to enhance documentation, scripting efficiency, configuration validation, and operational optimization

Profile

• Strong hands-on background in enterprise networking
• Proven experience in SD-WAN deployments and security migrations
• Deep understanding of routing, switching, WAN, and edge technologies
• Experience managing structured, large-scale infrastructure migrations
• Ability to handle multiple concurrent projects in dynamic environments
• Excellent stakeholder communication skills (remote and on-site)
• AI-First mindset — proactively integrating AI and automation tools to optimize design processes, troubleshooting workflows, documentation quality, and overall engineering efficiency
• Comfortable working in highly structured, migration-driven environments with defined timelines and change windows
