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
