The role also drives innovation through evaluation of emerging technologies, vendor strategies, and adoption of AI, AIOps, and agentic AI capabilities. As a senior leader, it builds and mentors a high-performing engineering team, drives vendor alignment, and serves as a trusted technical advisor to executive leadership on network evolution, risk, and modernization priorities.

** Job Description*
* + Define and own the global network engineering strategy across WAN, LAN, WiFi, and internet edge domains, enabling consistent, scalable, and high-quality connectivity across the enterprise

+ Partner with product owners to develop and execute a multi-year network roadmap, balancing modernization, risk mitigation, capacity growth, and cost optimization

+ Drive context-aware network design by adapting global standards to site-specific factors such as RF conditions, user density, and local constraints

+ Collaborate with Network Operations to translate recurring service instability patterns into engineering-led design improvements that enhance availability and performance

+ Establish, publish, and continuously evolve global network standards, reference architectures, design patterns, and configuration baselines

+ Lead engineering governance for technology selection, lifecycle management, and design reviews, ensuring compliance, scalability, and operational effectiveness

+ Define and enforce engineering KPIs and quality metrics (e.g., performance, resilience, standards compliance) across regions and vendor ecosystems

+ Provide strategic technical guidance to network product owners on lifecycle management (EOL/EOS), risk posture, security architecture, and modernization priorities

+ Integrate security-by-design principles into all network architectures in partnership with Information Security, including NAC, segmentation, secure access models, and policy enforcement

+ Ensure secure and resilient design patterns for hybrid connectivity models covering office, remote, and cloud environments, and drive remediation of identified security risks

+ Identify systemic drivers of network instability and lead structural design improvements, resilience enhancements, and capacity planning initiatives

+ Define and enhance network observability strategy, including telemetry standards, actionable dashboards, alerting models, and service health indicators

+ Lead initiatives to correlate network telemetry with end-user experience metrics (e.g., collaboration quality, latency, packet loss, WiFi performance) to identify root causes of user impact

+ Collaborate with monitoring and platform teams to continuously improve observability tools and instrumentation, ensuring network performance is measured in business-relevant outcomes

+ Conduct ongoing industry research to evaluate emerging networking technologies and identify opportunities for innovation aligned with business needs

+ Sponsor and lead Proof of Concept and Proof of Value initiatives for new technologies, including advancements in LAN, WiFi, WAN, security, and observability

+ Partner with vendors and internal teams to introduce AI, AIOps, and agentic AI capabilities in networking, such as anomaly detection, event correlation, predictive insights, and automated remediation

+ Drive adoption of network automation practices, including APIs, orchestration frameworks, and standardized design patterns to improve efficiency, consistency, and change reliability

+ Lead strategic vendor engagement by aligning vendor roadmaps with enterprise objectives and influencing product direction where required

+ Engage with business and technology stakeholders to translate requirements into engineering solutions and evolve global network standards

+ Partner closely with product and platform teams to align network design with evolving enterprise needs, including cloud adoption, collaboration platforms, and digital workplace initiatives
