• Project execution: Drive and manage the successful delivery of complex network projects, ensuring milestones are met and issues are resolved promptly.
• Stakeholder communication: Develop and deliver clear presentations to leadership and other teams to communicate strategy, status updates, and performance metrics.
• Data analysis: Use strong data analysis and Excel skills to understand and reconcile cost, inventory, capacity, trend, risk, and performance metrics.
• Collaboration: Work closely with systems, cloud, security, operations, and application teams to integrate best practices across the technology stack.
• Documentation & support: Develop and maintain detailed documentation of network designs, configurations, topologies, and processes; provide technical guidance and support to other team members.
• Continuous improvement: Research, evaluate, and recommend new technologies, tools, and best practices to advance our network capabilities.
