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
