About the role

Lead the design, validation and deployment of large-scale cloud network architectures across packet and optical networking, automation, telemetry and operations, influencing architectural decisions and driving live-site accountability in a hyperscale AI-driven infrastructure.

Responsibilities

  • Drive the creation and adoption of technologies, protocols and solutions that define reliable, secure, scalable, cost-effective and high-performance large-scale network architectures and designs.
  • Work across multiple teams and organizations to develop network architectures, lead architecture and design reviews, and drive technical decisions across functionality, performance, scale, reliability, operations, security and cost.
  • Develop and drive new approaches that address fundamental weaknesses in network architecture, processes, tooling and engineering capabilities before they result in customer or business impact, using automation and infrastructure as code to enable improvements at scale.
  • Provide end-to-end technical leadership across packet and optical networking, hardware, device operating systems, telemetry and automation, while influencing internal engineering teams, technology suppliers and other partners.
  • Design and advance automated network testing, validation, telemetry and analytics that identify failures and regressions earlier, improve troubleshooting at scale and explore the application of artificial intelligence and machine learning to network operations.
  • Lead the diagnosis and root-cause analysis of complex, multi-layer live-site issues, use production and telemetry data to identify systemic problems, and translate those learnings into durable improvements in network architecture, automation and engineering practices.
  • Participate in and lead on-call duties for production incidents, provide technical leadership through complex incidents, and mentor and coach engineers in network architecture, engineering, DevOps and live-site practices.

Qualifications

  • Doctorate Degree in Electrical Engineering, Optical Engineering, Computer Science, Information Technology, or related field AND technical experience in network design, development, and automation OR Master's Degree in Electrical Engineering, Optical Engineering, Computer Science, Information Technology, or related field AND technical experience in network design, development, and automation OR Bachelor's Degree in Electrical Engineering, Optical Engineering, Computer Science, Information Technology, or related field AND technical experience in network design, development, and automation OR equivalent experience.
  • Advanced technical experience defining, designing, developing or operating large-scale network architectures and taking major network solutions from architecture through validation and production deployment.
  • Experience with Software-Defined Networking (SDN), controller-based networking or centrally orchestrated traffic-engineering systems, including the programming and operation of network forwarding paths, tunnels or routing state.
  • Deep experience with network architecture and routing technologies, including BGP, IS-IS, MPLS, SR or comparable large-scale routing and traffic-engineering technologies.
  • Experience designing for the interaction between centralized network control and distributed router control planes, including convergence, fallback routing, failure handling, state consistency and failure-domain isolation.
  • Experience developing or influencing network automation, infrastructure as code, telemetry, testing or validation systems used to safely deploy and operate network infrastructure at scale.
  • Experience providing technical leadership during complex, multi-layer production incidents and translating operational findings into durable improvements in architecture, software, hardware, automation or engineering standards.
  • Ability to meet Microsoft, customer and/or government security screening requirements (Microsoft Cloud Background Check).
