Senior Networking Engineer

ABOUT THE ROLE

In this role, you will join a network automation team designing, configuring, and validating SD-WAN and service-provider routing solutions for enterprise and telecom clients. You will combine deep Cisco IOS and multi-vendor routing expertise with Python-based network automation, Cisco NSO/YANG service orchestration, and test-case automation to deliver reliable, well-documented network configurations across physical and virtual (ESXi) environments.

RESPONSIBILITIES

• Configure, optimize, and troubleshoot SD-WAN networks, including interoperability with legacy routing protocols (OSPF, BGP)
• Validate service-provider routing and network scenarios spanning IP/MPLS, BNG, and L3VPN
• Support network automation and service orchestration using Cisco NSO and YANG data models
• Write Python scripts to automate configuration, testing, and complex operational processes, increasing engineering efficiency
• Build and run test-case automation, including manual test definition and traffic stream configuration/automation on Spirent TestCenter and Spirent Cyberflood
• Diagnose and troubleshoot issues across Python code, network configuration, and physical/virtual (ESXi) environments
• Analyze, verify, and optimize client requirements to improve solution quality and performance
• Apply SDN/virtualization technologies (e.g., Nuage) to telco cloud and infrastructure-as-code initiatives
• Use Git for version control and collaborate cross-functionally (e.g., via Jira) throughout delivery

REQUIREMENTS

• Senior-level network engineering background with strong Cisco IOS and multi-vendor routing/switching expertise
• Hands-on experience configuring, optimizing, and troubleshooting SD-WAN networks
• Service-provider routing depth: MPLS, BGP, OSPF, L3VPN, BNG - telecom/ISP environment experience valued
• Proficiency in Python for network automation and test-case automation
• Experience with Git version control
• Experience troubleshooting network, code, and virtualization (ESXi) issues
• Strong client-facing skills: ability to analyze, verify, and optimize technical requirements
• Comfortable working in English within a multicultural, cross-functional environment
• Flexibility to regularly overlap with the US-based team for meetings, typically between 6:00 PM and 8:00 PM CET/CEST, with flexible scheduling of working hours.
