Job DescriptionSenior Network Engineer Global Network ServicesPosition Summary:As a Senior Network Engineer within ADMs Global Technology organization, you will lead the design, governance, and transformation of enterprise LAN, routing, and switching solutions that form the backbone of ADMs global connectivity. This role blends deep technical expertise with strong leadership, executive communication, and financial stewardship. You will ensure ADMs enterprise networkspanning campus LANs, data center fabrics, WAN/SD-WAN, and firewallsdelivers high performance, resiliency, and security while directly enabling business outcomes. By defining robust architecture standards, optimizing routing protocols, advancing automation, and applying analytics-driven insights, you will ensure ADM achieves simplified, scalable, and reliable connectivity worldwide.Key Responsibilities:LAN, Routing & Switching Architecture:Design, standardize, and govern ADMs global LAN and routing architectures, including data center switching, campus LAN, and site-level connectivity. Define resilient designs that leverage routing protocols such as OSPF, BGP, EIGRP, and IS-IS to ensure deterministic, scalable, and secure traffic flows. Produce reference architectures, detailed design templates, and technology roadmaps to guide enterprise-wide implementations. Provide executive-level communication to ensure alignment of technical standards with ADMs strategic priorities.Routing Protocol Optimization & Standards:Lead the development, optimization, and governance of enterprise-wide routing protocols, ensuring stability, convergence, and scalability across ADMs global footprint. Drive adoption of best practices in route redistribution, summarization, path optimization, and high-availability design. Partner with operations teams to troubleshoot, tune, and optimize complex routing scenarios, ensuring predictable and resilient outcomes across LAN and WAN environments.Technology Innovation & Business Alignment:Evaluate and implement next-generation routing and switching technologies, working with key suppliers, including campus fabric designs, SD-Access, and advanced WAN/SD-WAN solutions. Conduct proof of concept and pilots that demonstrate improved performance, resiliency, and cost efficiency. Prepare business cases supported by ROI, TCO, and operational impact analyses, ensuring that network investments align directly with ADMs enterprise strategies.Solution Development, Testing & Certification:Develop and certify network designs through rigorous testing of LAN, routing, and security capabilities. Create high- and low-level design documentation, test cases, and validation plans to ensure enterprise readiness. Partner with vendors and project teams to align solutions with ADMs performance, resiliency, and compliance requirements. Provide clear, structured communications to executives and technical leaders on solution readiness and risk.Project Delivery & Execution Excellence:Serve as the technical lead on PMO-driven and enterprise projects, ensuring LAN and routing requirements are captured, designs are validated, and risks are mitigated throughout the lifecycle. Produce thorough design documentation, coordinate cross-functional reviews, and facilitate smooth transitions into production. Maintain strong executive communications regarding project scope, risks, and financials, ensuring transparency and confidence.Operational Expertise & Incident Leadership:Incident Leadership is a collaborative partnership between Network Engineering and Network Operations to ensure production networks remain stable, resilient, and continuously improving. Engineers act as trusted SMEs for high-priority incidents, working with Operations to restore services quickly and conduct thorough root cause analysis. Together, the teams focus on prevention by embedding lessons learned into future designs, tuning routing protocols, optimizing LAN reliability, and automating routine tasks. This combined approach ensures critical issues are solved quickly, risks are reduced, and the network continues to evolve toward greater resiliency and efficiency.Automation, Analytics & Continuous Improvement:Advance ADMs network maturity by introducing automation and analytics into LAN and routing environments. Implement configuration automation, monitoring dashboards, and data-driven analytics to ensure proactive detection of anomalies and optimization of routing behaviors. Champion continuous improvement, simplifying network operations and driving efficiency while mentoring peers and junior engineers.Qualifications & Preferred Certifications:
