Principal Network Engineer - Deployments

About the Role

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.

This role requires approximately 50% travel to data centers, offices, partner locations, and other sites based on business and project needs.

What You’ll Do

• 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
• Travel approximately 50% to support infrastructure deployments, site assessments, technical reviews, incident response, and collaboration with internal and external partners

Minimum Qualifications

• Bachelor’s degree in Computer Science, Engineering, or a related field (or equivalent practical experience)
• 10+ years of experience designing and operating large-scale network infrastructure in cloud, hyperscale, ISP, or enterprise environments
• Deep expertise in network architecture, operations, and production support at scale
• Expert-level understanding of networking protocols and technologies, including BGP, OSPF, IS-IS, MPLS, TCP/IP, and IPv4/IPv6
• Proven experience architecting and operating mission-critical network infrastructure
• Demonstrated technical leadership across complex, cross-functional engineering initiatives
• Strong troubleshooting, systems-thinking, and problem-solving skills
• Strong communication skills with the ability to influence technical direction across organizations
• Ability and willingness to travel approximately 50%, including travel to data centers and other infrastructure sites
• Willingness to participate in on-call rotations supporting production infrastructure

Preferred Qualifications

• Experience with high-performance networking technologies such as InfiniBand and RoCE
• Deep knowledge of VXLAN, EVPN, and modern data center networking architectures
• Experience with network automation and scripting using Python or similar technologies
• Familiarity with network observability, telemetry, and monitoring platforms
• Experience with network modeling and programmability frameworks such as YANG, OpenConfig, and NETCONF
• Experience with cloud networking and hybrid infrastructure environments
• Familiarity with GPU cluster networking and AI/HPC infrastructure environments
• Experience designing low-latency, highly resilient networking systems at hyperscale

What We’re Looking For

• A highly technical networking leader who can define architecture and strategy for complex infrastructure environments
• A systems thinker who understands the interaction between networking, compute, storage, and distributed applications
• Someone who takes ownership of critical infrastructure systems and proactively drives continuous improvement
• A pragmatic engineer who balances reliability, scalability, performance, and operational simplicity
• A mentor and technical multiplier who raises the engineering bar across teams
• A collaborative leader capable of influencing cross-functional organizations and driving alignment on key technical decisions
