About the Role

Andromeda's infrastructure team designs, deploys, and operates large-scale GPU clusters. The Network Engineer will design and implement the networks for these clusters, including compute fabric, storage network, front-end, and out-of-band management. This role involves collaboration with the Cluster Architect on design and deployment engineers on site for validation, reporting to the Head of Infrastructure.

  • Design and capacity plan for storage traffic, tenant access, and internet and cloud interconnect.
  • Develop cabling plans, optics BOMs, and labeling standards.
  • Perform fabric bring-up, NCCL and fabric performance testing, and sign-off for acceptance.
  • Serve as an escalation point for fabric issues during deployment and in Day 2 operations.
  • Develop configuration templates and tooling for automated builds.

Requirements

  • Hands-on design and bring-up of InfiniBand or RoCE fabrics for clusters of 1,000+ GPUs.
  • Experience with NVIDIA UFM and switch operating systems such as Cumulus or SONiC.

About the Company

  • Andromeda is a market and infrastructure platform to buy, sell, and operate compute.
  • We believe demand for compute will grow exponentially.
  • We believe every spare electron should be made productive for AI and we're building the platform that makes that possible.
  • We sit at the center of three forces: Companies that need reliable, high-performance compute fast; A fragmented global supply of GPUs across hyperscalers, neoclouds, and independent data centers; Capital, risk, and operational complexity that most teams are not equipped to manage.
  • When we succeed, trillions of dollars of compute will flow through Andromeda.
  • In five years, Andromeda won't just participate in the AI infrastructure market. We will shape it.

  • Andromeda Cluster is an equal opportunity employer.
  • We celebrate diversity and are committed to creating an inclusive environment for all employees.
