Principal Front-End Network Engineer

Role description

Role Overview

The Principal Front-End Network Engineer will provide technical leadership across Nscale's front-end networking domain, owning the reliability, scalability, and long-term evolution of high-performance Ethernet front-end networks.

What You Will Do

Designing, reviewing, and evolving large-scale Ethernet leaf-spine / Clos fabric architectures, acting as the senior-most escalation point for complex front-end network incidents, and driving cross-team initiatives to improve fabric reliability and performance predictability.

Why It Might Be a Fit

The role requires a systems-level mindset, balancing performance, reliability, scalability, and operational cost at the highest level, and a proven ability to lead complex technical initiatives across teams and influence strategy without direct authority.

Requirements

• 12+ years of experience in network engineering, with deep focus on hyperscale data centre, cloud, or AI infrastructure networking
• Expert-level operational and architectural experience with large-scale Ethernet data centre fabrics (leaf-spine / Clos topologies)
• Strong hands-on expertise with Nvidia (Cumulus), Arista(EOS / Etherlink) and/or Nokia(7220 IXR, 7250 IXR, 7750 SR series) platforms in production environments at scale
• Deep understanding of modern data centre routing and control planes (BGP, OSPF, ECMP, EVPN-VXLAN)
• Proven experience with long-haul circuits, DCI, and optical transport (dark fiber, carrier Ethernet, coherent optics, ZR/ZR+)
• Strong background in storage networking over Ethernet and shared storage connectivity at hyperscale
• Demonstrated ability to debug and resolve complex cross-layer issues spanning hardware, optics, routing, and application layers
• Proven ability to lead complex technical initiatives across teams and influence strategy without direct authority

Benefits

• Highly competitive package (base + equity) with reviews every 12 months
• Dynamic progression plan tailored to your ambitions
• Flexible paid time off
• Parental leave
• Retirement plan participation
• Medical, dental, and vision benefits
