## About the role

We are looking for a Network Architect to own the design, deployment, and operation of the network connecting XFRA’s distributed compute fleet. Your scope will span high-performance networking within GPU clusters, north-south connectivity between compute sites and customers, and the wide-area architecture connecting our fleet to cloud platforms and compute partners. You will turn workload requirements into practical designs that balance performance, availability, security, deployment speed, and cost.

## What they're looking for

- 8+ years of relevant network engineering experience, or equivalent demonstrated expertise, including ownership of production architecture and hands-on implementation
- Strong experience with both data center networks and WAN or ISP connectivity across multiple sites
- Deep understanding of TCP/IP, BGP, IPv4/IPv6, routing, switching, segmentation, VPNs, firewalls, QoS, and high-availability design
- Practical understanding of fiber access and carrier service models, including how to validate real performance, availability, and commercial service commitments
- Experience designing and troubleshooting high-speed server networks, including NICs, optics, cabling, MTU, congestion, and oversubscription
- Ability to translate application traffic patterns and service objectives into network requirements, and explain performance, resilience, and cost tradeoffs clearly
