Staff Front-End Network Engineer

The Network Operations and Engineering teams at Nscale operate some of the most demanding networking environments in the industry, supporting large-scale AI GPU clusters where network performance directly impacts customer outcomes., This role focuses on owning and evolving the reliability, scalability, and operational excellence of our high-performance Ethernet front-end networks. These networks support inference traffic, cluster management, data ingress/egress, shared storage connectivity, long-haul circuits, and carrier handoffs.

You will act as a key technical leader and domain expert, driving architecture decisions, improving operational practices, and helping solve the most complex networking challenges in the front-end network stack. While not the ultimate technical authority, you will significantly influence design direction and cross-team outcomes.

What You’ll Be Doing

• Leading technical direction and operational improvements for Nscale’s front-end AI infrastructure networks within your domain
• Designing, reviewing, and evolving large-scale Ethernet leaf-spine / Clos fabric architectures (Arista and Nokia platforms) to support growth, inference workloads, and storage requirements
• Serving as a senior escalation point for complex front-end network incidents and driving deep technical root cause analysis and remediation
• Driving cross-team initiatives to improve fabric reliability, performance consistency, observability, and operational maturity
• Defining and evolving engineering standards for hardware configuration, routing, congestion management, firmware lifecycle, automation, and change safety across Nvidia Cumulus, Arista EOS, and Nokia platforms
• Partnering with SRE, Compute Platform, Storage, and Network Architecture teams to influence end-to-end system design, including DCI and storage networking integration
• Mentoring senior engineers and contributing to the growth of technical excellence across the organization
• Delivering measurable improvements in uptime, latency consistency, capacity efficiency, and incident reduction for front-end services

• 10-12+ years of experience in network engineering, with a strong focus on hyperscale data center, cloud, or AI infrastructure networking
• Deep hands-on experience with large-scale Ethernet data center fabrics (leaf-spine / Clos topologies)
• Strong production expertise with Nvidia (Cumulus), Arista EOS, and/or Nokia platforms at scale
• Solid understanding of data center routing and control planes (BGP, OSPF, ECMP, EVPN-VXLAN)
• Experience with long-haul circuits, DCI, and optical transport (dark fiber, carrier Ethernet, coherent optics, ZR/ZR+)
• Strong understanding of storage networking over Ethernet in large-scale environments
• Ability to debug and resolve complex cross-layer issues across hardware, optics, routing, and application layers
• Proven ability to lead technical initiatives across teams and influence outcomes without formal authority
• Strong systems thinking, balancing performance, reliability, scalability, and operational efficiency

Nice to Have

• Experience operating Arista, Nokia, or Nvidia networking platforms at hyperscale
• Familiarity with AI infrastructure network design patterns (inference, management, storage tiers)
• Exposure to DCI / long-haul optical or carrier network design and operations
• Strong automation experience (Python, Ansible, telemetry pipelines, validation frameworks)
• Experience contributing to infrastructure strategy or large-scale platform improvements
