## Description

We are seeking a Principal Network Engineer to lead the architecture, design, and operation of high-performance network infrastructure across large-scale data center and cloud environments. This is a highly strategic technical leadership role focused on defining network architecture, driving long-term infrastructure direction, and ensuring the reliability, scalability, and efficiency of mission-critical networking systems at significant scale.

You will serve as a senior technical authority across networking domains, partnering closely with infrastructure, platform, systems, and hardware teams to solve complex networking challenges and influence the future evolution of our infrastructure platforms.

As a Principal Engineer, you will establish engineering standards, guide cross-functional technical strategy, mentor senior engineers, and lead critical architectural decisions across the organization., * Lead the architecture, design, deployment, and operation of large-scale network infrastructure across data center and cloud environments

 * Define and drive technical strategy for core networking systems and infrastructure platforms
 * Own architectural decisions across routing, switching, transport, and overlay networking technologies (e.g., VXLAN, EVPN)
 * Design highly available, scalable, and resilient network systems supporting mission-critical services
 * Diagnose and resolve complex, cross-layer networking issues spanning hardware, software, systems, and infrastructure domains
 * Drive network automation, observability, and operational tooling initiatives to improve reliability and efficiency
 * Establish and evolve network architecture standards, operational best practices, and engineering processes
 * Partner cross-functionally with platform, systems, hardware, and operations teams to deliver end-to-end infrastructure solutions
 * Lead technical reviews and guide long-term network infrastructure roadmap planning
 * Mentor senior and staff-level engineers while elevating technical standards across the organization
 * Drive operational excellence and reliability initiatives, including continuous improvement of production support processes
