Summar

y:We are seeking a highly skilled Network Architect to lead the design and implementation of our hybrid and multi-cloud network environment. This role focuses on building a modern, scalable architecture across multiple hyperscalers in FedRamp versions—including AWS, Azure, OCI, and private cloud—while leveraging Cisco SD-WAN as the strategic connectivity platform. This role also requires the ability to clearly present architectural strategies and designs across the organization, communicate the business value behind technical decisions, and effectively sell and defend the proposed architecture to both technical stakeholders and executive leadershi
