Senior Data Center Networking Architect (Subject Matter Expert)

About the Team

The Networking team brings together expertise across network architecture, software-defined networking (SDN), network virtualization, and high-speed connectivity to build hyperscale infrastructure serving billions of users globally.

This team is responsible for designing and evolving next-generation data center networking architectures that deliver high performance, scalability, and resilience at global scale.


Role Overview

We are seeking a Senior Data Center Networking Architect (SME) with deep expertise in designing and architecting large-scale data center networks.

This role will focus on end-to-end network architecture, driving design standards, scalability strategies, and next-generation network evolution across hyperscale environments.

You will operate as a technical authority, influencing architecture decisions across data center, backbone, cloud, and edge networks.


Key Responsibilities

  • Lead the architecture and design of hyperscale data center networks, including:
    • Spine-leaf / CLOS architectures
    • Fabric design and scalability models
    • High availability and fault-tolerant designs
  • Define and drive network architecture standards, design principles, and best practices across global deployments
  • Architect high-performance, low-latency, and highly scalable network fabrics to support massive workloads
  • Design and optimize Layer 2 / Layer 3 network architectures, including:
    • BGP, EVPN-VXLAN overlays
    • MPLS and traffic engineering strategies
    • Underlay/overlay design
  • Lead network evolution initiatives, including:
    • Disaggregated networking
    • SDN and network automation
    • Intent-based networking
  • Collaborate with cross-functional teams (compute, storage, SRE, platform engineering) to ensure seamless integration of network architecture with infrastructure and applications
  • Work closely with vendors, ODMs, and chipset providers on:
    • Hardware/software co-design
    • Network device evaluation and validation
  • Provide SME-level guidance on:
    • Capacity planning and scaling strategies
    • Network performance optimization
    • Failure domain isolation and resiliency
  • Contribute to global network strategy, including backbone, inter-DC connectivity, and hybrid cloud networking
  • Travel may be required (15–30%)

Minimum Qualifications

  • Bachelor’s degree in Computer Science, Engineering, or related field
  • 10–15+ years of experience in network design and architecture, with strong focus on data center environments
  • Proven experience designing hyperscale data center networks
  • Deep expertise in:
    • TCP/IP, BGP, OSPF, IS-IS
    • EVPN-VXLAN and modern DC fabrics
    • MPLS and traffic engineering
  • Strong understanding of CLOS/spine-leaf architectures at scale
  • Experience with network observability and telemetry (SNMP, NetFlow/sFlow, streaming telemetry)
  • Hands-on experience with major network vendors and/or whitebox/disaggregated networking
  • Ability to operate as a technical leader and SME across global teams

Preferred Qualifications

  • Experience in hyperscale or cloud environments
  • Strong knowledge of SDN, automation, and programmability (Python, APIs)
  • Familiarity with merchant silicon (e.g., Broadcom, Barefoot)
  • Experience with multi-cloud networking (AWS, GCP, Azure, etc.)
  • Understanding of IPv6 and dual-stack architectures

What We’re Looking For

  • A true SME in Data Center Networking Architecture
  • Someone who designs at scale, not just operates networks
  • Strong ability to translate business growth into scalable network design
  • Experience influencing architecture decisions across global infrastructure
